<li> \b plot is the complete drawn image, including the axes, the graphs, the key and all other visual elements
It is drawn by the invisible JKQTBasePlotter, which is typically controlled by an actual widget like JKQTPlotter
<li> <b>plot element</b> any sub element of the plot, e.g. a single coordinate axis, the key, but also any graph/curve
<li> \b graph is a single curve/image/geometric element in the plot, typically derived from JKQTPGraph (see also
\ref jkqtplotter_graphsgroup_classstructure_basics )
<li> <b>geometric element</b> is a special graph that does not represent a curve based on data from the JKQTPDatastore,
but a single graphic element, like a rectangle/circle/line/..., some text, a single symbol. These elements are typically
derived from JKQTPGeometricPlotElement
<li> \b annotation is a plot element, which is used to annotate the graphs/plot, e.g. some text. These elements are typically
derived from JKQTPPlotAnnotationElement
<li> \b key is the legend of the plot
<li> <b>coordinate axis</b> is each of the x- or y-axis (there might be addition axes, e.g. when showing a color-scale)

\defgroup jkqtplotter_basicprinciples Basic Principles of JKQTPlotter
\ingroup jkqtplotter_general
This page documents some basic principles behind the design of the JKQTPlotter library.
\tableofcontents
\section jkqtplotter_basicprinciples_datastorage Datastorage
Data is stored in an (internal) instance of JKQTPDatastore, which is accessible through JKQTPlotter::getDatastore() or JKQTBasePlotter::getDatastore().
This datastore can either own its data (which is done here, as we copy the data into the store
e.g. by calling JKQTPDatastore::addCopiedColumn(), or it can merely reference to the data (then
data needs to be available as array of \c double values).
In addition JKQTPDatastore provides different functions to add or edit the contained data. Amongst others it also provides a C++ StdLib-type iterator
interface to access the data.
\see JKQTPDatastore,
\ref jkqtpdatastorage ,
\ref jkqtp_extut_datamanagement
\section jkqtplotter_basicprinciples_graphs_and_mixins Graphs & Mix-Ins
Each graph is represented by a class derived from JKQTPPlotElement (e.g. JKQTPXYLineGraph,
which shows data as a scatter of symbols that may (or may not) be connected by a line).
There is a complete hirarchy of graph base classes, from which different graphs (or more general plot elements) are derived,
see \ref jkqtplotter_graphsgroup_classstructure_basics .
Constructing a graph class does not yet add it to the plotter. To add it, call JKQTBasePlotter::addGraph() / JKQTPlotter::addGraph(). Only
after this step, the graph is displayed. You can modify the apperance of the graph (e.g. colors, name in the key ...) by setting
properties in the graph class instance.
Most graph peroperties are inserted into the graph class via <a href="https://en.wikipedia.org/wiki/Mixin">mix-in</a> classes.
A Mixin allows to inject the same code into different classes, but does not require these classes to be in the same inheritance
tree. The style of mix-in programming used in the JKQTPlotter library is multiple-inheritance. So a graph class is derived from
JKQTPGraph but also has additional parent classes from \ref jkqtplotter_basegraphs_stylemixins like:
- JKQTPGraphLineStyleMixin which provides line-styling
- JKQTPGraphSymbolStyleMixin which provides styling for graph symbols
- JKQTPGraphFillStyleMixin which provides fill styles
- ...

\tableofcontents
\section jkqtplotter_graphsgroup_classstructure Graph Class Structure
\subsection jkqtplotter_graphsgroup_classstructure_basics Graph Classes
Each type of graph is represented by another class, which has to be derived from JKQTPPlotElement. This class provides a basic virtual interface
that allows JKQTPlotter to draw the graphs represented by them. This interface consists of these functions:
- JKQTPPlotElement::draw() draws the graph onto a given JKQTPEnhancedPainter (derived from <a href="http://doc.qt.io/qt-5/qpainter.html">QPainter</a>)
- JKQTPPlotElement::drawKeyMarker() draws the small marker image in the plot legend
- JKQTPPlotElement::getKeyLabelColor() returns a color for the legend entry for the graph
- JKQTPPlotElement::getXMinMax() returns the extent of the graph in x-direction (e.g. for auto-zooming)
- JKQTPPlotElement::getYMinMax() returns the extent of the graph in Y-direction (e.g. for auto-zooming)
.
In addition to these basic functions, there are additional functions that can be used to draw something outside the actual plot rectangle.
These are used to e.g. add color-scales to the side of the graph:
- JKQTPPlotElement::getOutsideSize() returns the amount of space required outside the plot rectangle
- JKQTPPlotElement::drawOutside() draws the elements outside the plot rectangle
.
Usually if writing a new graph, one would not directly
derive from JKQTPPlotElement, but from a cass in it's hirarchy of children. These children already provide certain facilities for certain types of graphs.

\subsection jkqtplotter_graphsgroup_classstructure_mixins Mix-In Classes for Graphs
\see \ref jkqtplotter_basicprinciples_graphs_and_mixins
In addition there are mix-in classes that are used via multiple inheritance
that add additional features and properties to a graph. A prominent example are the classes for \ref jkqtplotter_basegraphserrors "error indicators".
With these there are usually two variants of one type of graph: One without error indicators and one with error indicators, e.g.:
- JKQTPXYLineGraph shows lines+symbols graphs made up from x/y-value pairs for each data point.
- JKQTPXYLineErrorGraph extends JKQTPXYLineGraph with error indicator drawing/properties provided by JKQTPXYGraphErrors
.
This approach allows to keep interfaces and appearance recognizeable over different graph classes and locates the source code
for a feature like error indicators in a single/in few class(es).
Another example of such a class is JKQTPColorPaletteStyleAndToolsMixin, which provides functions that allow to use color palettes. It is
mainly used for the \ref jkqtplotter_imagelots "Image/Matrix graphs", but also by e.g. JKQTPXYParametrizedScatterGraph.

This datastore can either own its data (which is done here, as we copy the data into the store

data needs to be available as array of \c double values).

\section jkqtplotter_graphsgroup_classstructure_basics Graph Class Structure
Each type of graph is represented by another class, which has to be derived from JKQTPPlotElement. This class provides a basic virtual interface
that allows JKQTPlotter to draw the graphs represented by them. This interface consists of these functions:
- JKQTPPlotElement::draw() draws the graph onto a given JKQTPEnhancedPainter (derived from <a href="http://doc.qt.io/qt-5/qpainter.html">QPainter</a>)
- JKQTPPlotElement::drawKeyMarker() draws the small marker image in the plot legend
- JKQTPPlotElement::getKeyLabelColor() returns a color for the legend entry for the graph
- JKQTPPlotElement::getXMinMax() returns the extent of the graph in x-direction (e.g. for auto-zooming)
- JKQTPPlotElement::getYMinMax() returns the extent of the graph in Y-direction (e.g. for auto-zooming)
.
In addition to these basic functions, there are additional functions that can be used to draw something outside the actual plot rectangle.
These are used to e.g. add color-scales to the side of the graph:
- JKQTPPlotElement::getOutsideSize() returns the amount of space required outside the plot rectangle
- JKQTPPlotElement::drawOutside() draws the elements outside the plot rectangle
.
Usually if writing a new graph, one would not directly
derive from JKQTPPlotElement, but from a cass in it's hirarchy of children. These children already provide certain facilities for certain types of graphs.

\section jkqtplotter_graphsgroup_classstructure_mixins Mix-In Classes for Graphs
\see \ref jkqtplotter_mixins
In addition there are mix-in classes that are used via multiple inheritance
that add additional features and properties to a graph. A prominent example are the classes for \ref jkqtplotter_basegraphserrors "error indicators".
With these there are usually two variants of one type of graph: One without error indicators and one with error indicators, e.g.:
- JKQTPXYLineGraph shows lines+symbols graphs made up from x/y-value pairs for each data point.
- JKQTPXYLineErrorGraph extends JKQTPXYLineGraph with error indicator drawing/properties provided by JKQTPXYGraphErrors
.
This approach allows to keep interfaces and appearance recognizeable over different graph classes and locates the source code
for a feature like error indicators in a single/in few class(es).
Another example of such a class is JKQTPColorPaletteStyleAndToolsMixin, which provides functions that allow to use color palettes. It is
mainly used for the \ref jkqtplotter_imagelots "Image/Matrix graphs", but also by e.g. JKQTPXYParametrizedScatterGraph.

\defgroup jkqtplotter_naming Conventions: Naming and Plot Construction
\ingroup jkqtplotter_general
This page assembles the naming conventions behind the implementation and documentation of JKQTPlotter (cf. the image below):
<ul>
<li> \b plot is the complete drawn image, including the axes, the graphs, the key and all other visual elements
It is drawn by the invisible JKQTBasePlotter, which is typically controlled by an actual widget like JKQTPlotter
<li> <b>plot element</b> any sub element of the plot, e.g. a single coordinate axis, the key, but also any graph/curve
<li> \b graph is a single curve/image/geometric element in the plot, typically derived from JKQTPGraph (see also
\ref jkqtplotter_graphsgroup_classstructure_basics )
<li> <b>geometric element</b> is a special graph that does not represent a curve based on data from the JKQTPDatastore,
but a single geometric element, like a rectangle/circle/line/... These elements are typically
derived from JKQTPGeometricPlotElement
<li> \b annotation is a plot element, which is used to annotate the graphs/plot, e.g. some text. These elements are typically
derived from JKQTPPlotAnnotationElement
<li> \b key is the legend of the plot, showing a list of the graphs, each represented by a <b>entry marker</b> (showing the graphs color/symbol/...) and a <b>entry title</b>.
<li> <b>coordinate axis</b> is each of the x- or y-axis (there might be addition axes, e.g. when showing a color-scale). Each coordinate axis is composed from several elements: the axis line itself, an <b>axis label</b>, axis <b> ticks</b> and corresponding <b>tick labels</b> (major and a second set of minor ticks in between are available)
<li> <b>zero axis</b>: a pair of axes through the origin \c x=0 and \c y=0 of the coordinate system
<li> \b grid a grid of horizontal/vertical lines, drawn behind the graph and providing visual guidance for the viewer of the graph. The grid is actually a part of the coordinate axes, as the lines are positioned at the same position as the axis ticks
<li> <b>minor grid</b> in addition to the grid, corresponding to the major axis ticks, you can add additional lines that correspond to the minor axis ticks
<li> <b>color bar</b> some graphs use a color-scale (e.g. images or parametrized scatter graphs). The color bar displays the used color palette of that graph. It is typically positioned besides or above the plot.

\ingroup jkqtplotter_general
\defgroup jkqtplotter_general_usage_jkqtbaseplotter Usage of JKQTBasePlotter Non-Visible Class
\ingroup jkqtplotter_general_usage
It is also possible to use it in a standalone fashion to generate plots without generating a window.
Note that the baseplotter class still requires the \c widgets+gui modules of Qt, because it contains code to e.g.
display pint or export preview dialogs!
Here is an example of how to do this (it is taken from the command-line tool \ref JKQTPlotterDocImageRenderCmdLineTool):
First we generate the JKQTBasePlotter object and add some data to the internal JKQTPDatastore
\code
JKQTBasePlotter plot(true);
JKQTPDatastore* ds=plot.getDatastore();
size_t cx=ds->addCopiedColumn(QVector<double>{-1.5,-0.5,0.5,1.5,2.5},"x");
size_t cy=ds->addCopiedColumn(QVector<double>{-0.75,-0.3,-0.05,0.2,0.65},"y");
\endcode
Now we set the range of x/y plot coordinates ...
\code
plot.setXY(-0.8,2.2,-0.5,0.7);
\endcode
and the size of the widget, i.e. the size of the plot in the windowing system.
\code
plot.setWidgetSize(150,50);
\endcode
Now we can add graphs to the plotter, e.g.
\code
JKQTPXYLineGraph* g=new JKQTPXYLineGraph(&plot);
g->setXColumn(cx);
g->setYColumn(cy);
plot.addGraph(g);
\endcode
Finally we store an image of the plot as PNG-file:
\code
plot.saveAsPixelImage("output.png", false, "png");
\endcode
Alternatively you can obtain a QImage of the plot using JKQTBasePlotter::grabPixelImage() or copy the
image to the clipboard using JKQTBasePlotter::copyPixelImage(). Also storages as PDF and SVG is available via
JKQTBasePlotter::saveAsPDF() and JKQTBasePlotter::saveAsSVG().
With simlar code you can also integrate JKQTBasePlotter into your own widgets.
\defgroup jkqtplotter_general_usage_jkqtplotter Usage of JKQTPlotter Widget
\ingroup jkqtplotter_general_usage
JKQTPlotter is a plotter widget which wraps around a JKQTBasePlotter instanced that does the actual drawing.
A basic usage of JKQTPlotter looks like this:
\code{.cpp}
// create a new JKQTPlotter instance
JKQTPlotter* plot = new JKQTPlotter(parentWidget);
// fill two vectors with dtaa for a graph:
QVector<double> X, Y;
fillDataVectors(X, Y);
// make data available to the internal datastore of the plotter:
size_t columnX=plot->getDatastore()->addCopiedColumn(X, "x");
size_t columnY=plot->getDatastore()->addCopiedColumn(Y, "y");
// create a graph/curve, which displays the data
JKQTPXYLineGraph* graph1=new JKQTPXYLineGraph(plot);
graph1->setXColumn(columnX);
graph1->setYColumn(columnY);
graph1->setTitle(QObject::tr("graph title"));
plot->addGraph(graph1);
// autoscale the plot
plot->zoomToFit();
// alternatively set the axis dimension by hand:
plot->setXY(-10,10,-10,10);
\endcode
The result should look something like this:
\image html simpletest.png
Starting from this basic example, you can observe several important principles:
<ol>
<li> Data is stored in an (internal) instance of JKQTPDatastore, which is accessible through
JKQTPlotter::getDatastore().
This datastore can either own its data (which is done here, as we copy the data into the store
by calling JKQTPDatastore::addCopiedColumn(), or it can merely reference to the data (then
data needs to be available as array of \c double values).
<li> Naming conventions (excerpt from \ref jkqtplotter_naming ):
<ul>
<li> \b plot is the complete drawn image, including the axes, the graphs, the key and all other visual elements
<li> <b>plot element</b> any sub element of the plot, e.g. a single coordinate axis, the key, but also any graph/curve
<li> \b graph is a single curve/image/geometric element in the plot
<li> <b>geometric element</b> is a special graph that does not represent a curve based on data from the JKQTPDatastore,
but a single graphic element, like a rectangle/circle/line/..., some text, a single symbol
<li> \b key is the legend of the plot
<li> <b>coordinate axis</b> is each of the x- or y-axis (there might be addition axes, e.g. when showing a color-scale)
</ul>
<li> Each graph is represented by a class derived from JKQTPPlotElement (in the example we instanciated a JKQTPXYLineGraph,
which shows data as a scatter of symbols that may (or may not) be connected by a line).
Creating the graph class does not yet add it to the plotter. To add it, call JKQTPlotter::addGraph(). Only
after this sep, the graph is displayed. You can modify the apperance of the graph (e.g. colors,
name in the key ...) by setting properties in the graph class instance.
<li> You can auto-zoom the axis ranges of the plot by calling JKQTPlotter::zoomToFit(), or set them
exlicitly by calling JKQTPlotter::setXY(). The user can later zoom in/out by the mouse (and other means).
You can limit this zoom range by setting an absolute axis range, calling e.g. JKQTPlotter::setAbsoluteXY().
The the user cannot zoom farther out than the given range(s).
<li> If you want to style the plot itself, you need to set properties of the underlying JKQTBasePloter instance, which
is accessible through JKQTPlotter::getPlotter(). If you want to style the coordinate axes, you can acces their
representing objects by caling JKQTPlotter::getXAxis() or JKQTPlotter::getYAxis().
</ol>

\defgroup jkqtplotter_general_usage_qtcreator How to use JKQTPlotter in the Qt Form Designer
\ingroup jkqtplotter_general_usage
As JKQTPlotter is a standard Qt widget, you can also use it in Qt UI-files designed with the Qt From Designer (e.g. from within QTCreator).
For this to work you have to use the <a href="https://doc.qt.io/qt-6/designer-using-custom-widgets.html">Promote QWidget"-feature</a> of the form designer. The steps you need to take are detailed below:
<ol>
<li> add a new UI-file to your project and open it in the Form Editor. Then right-click the form and select `Promote Widgets ...`:
\image html uidesigner_step1.png
</li>
<li> In the dialog that opens, you have to define `JKQTPlotter` as a promotion to `QWidget` as shown below. Finally store the settings by clicking `Add` and closing the dialog with `Close`.
\image html uidesigner_step2.png
</li>
<li> Now you can add a `QWidget`from the side-bar to the form and then promote it to `JKQTPlotter`, by selecting and right-clicking the `QWidget` and then selecting `Promote To | JKQTPlotter`:
\image html uidesigner_step3.png
</li>
</ol>
\see \ref JKQTPlotterQtCreator <br> Also see \ref JKQTPlotterStyling for another example of using the Qt UI Designer with JKQTPlotter

* \copydetails jkqtplotter_general_usage_jkqtplotter
*
* Here is an example of how to do this (it is taken from the command-line tool \ref JKQTPlotterDocImageRenderCmdLineTool):
*
* First we generate the JKQTBasePlotter object and add some data to the internal JKQTPDatastore
* \code
* JKQTBasePlotter plot(true);
* JKQTPDatastore* ds=plot.getDatastore();
* size_t cx=ds->addCopiedColumn(QVector<double>{-1.5,-0.5,0.5,1.5,2.5},"x");
* size_t cy=ds->addCopiedColumn(QVector<double>{-0.75,-0.3,-0.05,0.2,0.65},"y");
* \endcode
*
* Now we set the range of x/y plot coordinates ...
* \code
* plot.setXY(-0.8,2.2,-0.5,0.7);
* \endcode
* and the size of the widget, i.e. the size of the plot in the windowing system.
* \code
* plot.setWidgetSize(150,50);
* \endcode
* Now we can add graphs to the plotter, e.g.
* \code
* JKQTPXYLineGraph* g=new JKQTPXYLineGraph(&plot);
* g->setXColumn(cx);
* g->setYColumn(cy);
* plot.addGraph(g);
* \endcode
* Finally we store an image of the plot as PNG-file:
* \code
* plot.saveAsPixelImage("output.png", false, "png");
* \endcode
* Alternatively you can obtain a QImage of the plot using grabPixelImage() or copy the
* image to the clipboard using copyPixelImage(). ALso storages as PDF and SVG is available via
* saveAsPDF() and saveAsSVG().
*
* With simlar code you can also integrate JKQTBasePlotter into your own widgets.

* \section JKQTPLOTTER_BASICUSAGE Basic Usage of JKQTPlotter
*
* JKQTPlotter is a plotter widget which wraps around a JKQTBasePlotter instanced that does the actual drawing.
* A basic usage of JKQTPlotter looks like this:
* \copydetails jkqtplotter_general_usage_jkqtbaseplotter
*
* \code{.cpp}
* // create a new JKQTPlotter instance
* JKQTPlotter* plot = new JKQTPlotter(parentWidget);
*
* // fill two vectors with dtaa for a graph:
* QVector<double> X, Y;
* fillDataVectors(X, Y);
*
* // make data available to the internal datastore of the plotter:
* size_t columnX=plot->getDatastore()->addCopiedColumn(X, "x");
* size_t columnY=plot->getDatastore()->addCopiedColumn(Y, "y");
*
* // create a graph/curve, which displays the data
* JKQTPXYLineGraph* graph1=new JKQTPXYLineGraph(plot);
* graph1->setXColumn(columnX);
* graph1->setYColumn(columnY);
* graph1->setTitle(QObject::tr("graph title"));
* plot->addGraph(graph1);
*
* // autoscale the plot
* plot->zoomToFit();
* // alternatively set the axis dimension by hand:
* plot->setXY(-10,10,-10,10);
* \endcode
*
* The result should look something like this:
*
* \image html simpletest.png
*
* Starting from this basic example, you can observe several important principles:
* <ol>
* <li> Data is stored in an (internal) instance of JKQTPDatastore, which is accessible through
* JKQTPlotter::getDatastore().
* This datastore can either own its data (which is done here, as we copy the data into the store
* by calling JKQTPDatastore::addCopiedColumn(), or it can merely reference to the data (then
* data needs to be available as array of \c double values).
* <li> Naming conventions (excerpt from \ref jkqtplotter_naming ):
* <ul>
* <li> \b plot is the complete drawn image, including the axes, the graphs, the key and all other visual elements
* <li> <b>plot element</b> any sub element of the plot, e.g. a single coordinate axis, the key, but also any graph/curve
* <li> \b graph is a single curve/image/geometric element in the plot
* <li> <b>geometric element</b> is a special graph that does not represent a curve based on data from the JKQTPDatastore,
* but a single graphic element, like a rectangle/circle/line/..., some text, a single symbol
* <li> \b key is the legend of the plot
* <li> <b>coordinate axis</b> is each of the x- or y-axis (there might be addition axes, e.g. when showing a color-scale)
* </ul>
* <li> Each graph is represented by a class derived from JKQTPPlotElement (in the example we instanciated a JKQTPXYLineGraph,
* which shows data as a scatter of symbols that may (or may not) be connected by a line).
* Creating the graph class does not yet add it to the plotter. To add it, call JKQTPlotter::addGraph(). Only
* after this sep, the graph is displayed. You can modify the apperance of the graph (e.g. colors,
* name in the key ...) by setting properties in the graph class instance.
* <li> You can auto-zoom the axis ranges of the plot by calling JKQTPlotter::zoomToFit(), or set them
* exlicitly by calling JKQTPlotter::setXY(). The user can later zoom in/out by the mouse (and other means).
* You can limit this zoom range by setting an absolute axis range, calling e.g. JKQTPlotter::setAbsoluteXY().
* The the user cannot zoom farther out than the given range(s).
* <li> If you want to style the plot itself, you need to set properties of the underlying JKQTBasePloter instance, which
* is accessible through JKQTPlotter::getPlotter(). If you want to style the coordinate axes, you can acces their
* representing objects by caling JKQTPlotter::getXAxis() or JKQTPlotter::getYAxis().
* </ol>

* \section JKQTPLOTTER_USEQTCREATOR How to use JKQTPlotter in the Qt Form Designer
*
* As JKQTPlotter is a standard Qt widget, you can also use it in Qt UI-files designed with the Qt From Designer (e.g. from within QTCreator).
* For this to work you have to use the <a href="https://doc.qt.io/qt-6/designer-using-custom-widgets.html">Promote QWidget"-feature</a> of the form designer. The steps you need to take are detailed below:
* <ol>
* <li> add a new UI-file to your project and open it in the Form Editor. Then right-click the form and select `Promote Widgets ...`:
*
* \image html uidesigner_step1.png
* </li>
* <li> In the dialog that opens, you have to define `JKQTPlotter` as a promotion to `QWidget` as shown below. Finally store the settings by clicking `Add` and closing the dialog with `Close`.
*
* \image html uidesigner_step2.png
* </li>
* <li> Now you can add a `QWidget`from the side-bar to the form and then promote it to `JKQTPlotter`, by selecting and right-clicking the `QWidget` and then selecting `Promote To | JKQTPlotter`:
*
* \image html uidesigner_step3.png
* </li>
* </ol>

* \see \ref JKQTPlotterQtCreator <br> Also see \ref JKQTPlotterStyling for another example of using the Qt UI Designer with JKQTPlotter
