/** \brief plotter widget for scientific plots (uses JKQTBasePlotter to do the actual drawing)
* \ingroup jkqtpplotterclasses
*
* This class is a QWidget-wrapper around JKQTBasePlotter. It uses the tools from JKQTBasePlotter
* to display scientific plots. This class mostly adds the Widget for the output and adds different
* types of user interactions.
*
* <b>Please have a look at the documentation of JKQTBasePlotter for details on the management of graphs
* and the formating/styling of the plot and graphs!</b>
*
* The rest of this documentation ins split into sections that each treat a special topic, as outlines below:
*
* \tableofcontents
*
*
* \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:
*
* \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 jkqtplotter_simpletest1.png
*
* Starting from this basic example, you can observe several important principles:
* # 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).
* # Naming conventions:
* - \b plot is the complete drawn image, including the axes, the graphs, the key and all other visual elements
* - <b>plot element</b> any sub element of the plot, e.g. a single coordinate axis, the key, but also any graph/curve
* - \b graph is a single curve/image/geometric element in the plot
* - <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
* - \b key is the legend of the plot
* - <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 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.
* # 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).
* # 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().
* .
*
* \see \ref JKQTPlotterSimpleTest and \see JKQTPlotterQtCreator
*
* \section JKQTPLOTTER_SYNCMULTIPLOT Synchronizing Several Plots
*
* Often a single plot is not sufficient, but several plots need to be aligned with respect to each other:
*
* \image html test_multiplot.png
*
* In the Qt Window this is achieved by placing several JKQTPlotter objects into a <a href="http://doc.qt.io/qt-5/qgridlayout.html">QGridLayout</a>.
* In order to support this alignment, also when exporting/printing a plot, and when the user interactions with the plot (e.g. zooming),
* JKQTPlotter offers an API which allows to :
* <ul>
* <li> <b>declare (grid-like) relations between plots for export/printing</b>
* \see setGridPrinting(), addGridPrintingPlotter(), clearGridPrintingPlotters(), setGridPrintingCurrentPos() and \ref JKQTBASEPLOTTER_SYNCMULTIPLOT_SYNC</li>
* <li> <b>synchronize axes/plots</b>
* \see synchronizeXToMaster(), synchronizeYToMaster(), resetMasterSynchronization() and \ref JKQTBASEPLOTTER_SYNCMULTIPLOT_GRIDPRINT</li>
* </ul>
*
*
* \note This API adopts and extends the possibilities of JKQTBasePlotter. Please see the documentation there for details:
* <ul>
* <li> \ref JKQTBASEPLOTTER_SYNCMULTIPLOT
* <ul>
* <li> \ref JKQTBASEPLOTTER_SYNCMULTIPLOT_SYNC</li>
* <li> \ref JKQTBASEPLOTTER_SYNCMULTIPLOT_GRIDPRINT</li>
* </ul>
* </ul>
*
*
*
* \section JKQTPLOTTER_USERINTERACTION User-Interactions/GUI Features
*
* JKQTPlotter offers a lot of user-interaction features out of the box. These are detailed below.
*
* \subsection JKQTPLOTTER_CONTEXTMENU Context Menu of JKQTPlotter
*
* The class JKQTPlotter has a context menu that already offers a lot of functionality.
*
* \image html jkqtplotter_defaultcontextmenu.png
*
* \image html contextmenu_graphvisibility.gif
*
* It allows to:
* <ul>
* <li> copy or save the data from the internal JKQTPDatastore</li>
* <li> copy or save the plot to an image file (PNG, PDF, ...), includes a softisticated export-preview dialog:
*
* \image html jkqtplotter_exportpreviewdialog.png
* </li>
* <li> print the plot (includes a softisticated print-preview dialog):
*
* \image html jkqtplotter_printpreview.png "Print Preview Dialog"
*
* \image html jkqtplotter_printpreview_relsize_mullinewidth_mulfonts.png "Print Preview Dialog with modified (relative) size, line-width and font-size"
* </li>
* <li> open a dialog with a table of the plot data:
*
* \image html jkqtplotter_datatabledialog.png "Data Table Dialog (with buttons to save or copy the data)"
* </li>
* <li> zoom into/out of the plot and determine an auto-zoom, which shows all of the plot data</li>
* <li> switch the visibility of the different graphs in the plot</li>
* </ul>
*
* You can activate this menu, by setting \c setContextMenuMode(jkqtpcmmStandardContextMenu); and binding a mouse-action (typically the right-click)
* to the context menu by calling \c deregisterMouseDragAction(Qt::RightButton,Qt::NoModifier) which deregisters any user actions from the rhs single
* mouse click. In that case, the context menu is opened by default (see setContextMenuMode() to choose the mode of the context menu).
*
*
* In addition JKQTPlotter provides several ways to customize this menu:
* - You can add additional actions to the JKQTPlotter, by calling `JKQTPlotter::addAction()` (i.e. using the default Qt mechanism)
* and/or by adding actions to the internal JKQTBasePlotter, using `JKQTBasePlotter::registerAdditionalAction()`
* - You can modify the menu, when it is displayed, by connecting a slot to the signal `JKQTPlotter::contextMenuOPened(x,y,menu)`:
* \code
* connect(plot, SIGNAL(contextMenuOpened(double, double, QMenu*)), this, SLOT(contextMenuOpened(double, double, QMenu*)));
*
* // ...
*
* void TestUserInteraction::contextMenuOpened(double x, double y, QMenu *contextMenu)
* {
* contextMenu->addSeparator();
* QAction* act=contextMenu->addMenu(QString("contextMenuOpened(x=%1, y=%2)").arg(x).arg(y))->addAction("user-added action");
* connect(act, &QAction::triggered, [x,y]() { QMessageBox::warning(nullptr, tr("Plot Context Menu"),
* tr("Context Menu was opened at x/y=%1/%2!").arg(x).arg(y),
* QMessageBox::Ok,
* QMessageBox::Ok); });
* labMouseAction->setText(QString("contextMenuOpened(x=%1, y=%2)").arg(x).arg(y));
* }
* \endcode
* .
*
* \subsection JKQTPLOTTER_SPECIALCONTEXTMENU Special (User-Defined) Context Menu of JKQTPlotter
*
* In addition to the standard context menu, JKQTPlotter can also be configures to display a special, user-defined context menu.
* To do so, call `\c setContextMenuMode(jkqtpcmmSpecialContextMenu) and set your menu, by calling \c setSpecialContextMenu()
* You can also combine the special menu and the standard menu, by calling \c setContextMenuMode(jkqtpcmmStandardAndSpecialContextMenu) .
*
* You can also use the signal contextMenuOpened() to modify the special context menu, but note that alterations to this menu are permanently
* stored in the special menu object. See contextMenuOpened() for a detailed discussion and ways to circumvent this!
*
*
* \subsection JKQTPLOTTER_TOOLBAR Toolbar of JKQTPlotter
*
* In addition to the context-menu, a JKQtPlotter also also provides a toolbar at its top that offers
* most of the functionality of the context menu. Usually this toolbar is enabled (see toolbarEnabled)
* and is in a mode where it is hidden, until the mouse moves over an area at the top of the plot (see toolbarAlwaysOn):
*
* \image html jkqtplotter_toolbar_hidden.png "Hidden Toolbar"
* \image html jkqtplotter_toolbar_shown.png "Shown Toolbar"
*
* \image html jkqtvanishtoolbar.gif
*
* If toolbarAlwaysOn is set to \c true (setToolbarAlwaysOn() ), the toolbar is always displayed:
*
* \image html jkqtplotter_toolbar_alwayson.png
*
* \see toolbarEnabled, toolbarAlwaysOn, \ref JKQTPlotterUserInteraction
*
*
*
* \subsection JKQTPLOTTER_ACTIONS QActions from a JKQTPlotter
* Often you want to allow the suer to operate a plot from a user-defined QToolBar or a QMenu/QMenuBar in your
* application (e.g. provide zooming commands ...). there are generally two ways to achieve this:
* <ol>
* <li> Simply connect home-brewn QAction instances to the slots provided by JKQTPlotter and JKQTBasePlotter.
* This also allows you to connect different plot properties to edit widgets in your forms.
* \code
* // add a checkbox to show and hide the position display label in the plot
* chkPositionDisplay=new QCheckBox(tr("show mouse cursor position"), this);
* chkPositionDisplay->setChecked(plot->isMousePositionShown());
* connect(chkPositionDisplay, SIGNAL(toggled(bool)), plot, SLOT(setMousePositionShown(bool)));
* \endcode
* </li>
* <li> For several functions (especially those also present in JKQTPlotter's context-emun, you can also find
* readily available QAction instances. these are available from JKQTBasePlotter (e.g. by JKQTBasePlotter::getActionPrint() ...).
* From JKQTPlotter you therefor have to use: <code>getPlotter()->getActionPrint()</code>
* \code
* // add some of the default QActions from the JKQTPlotter to the window menu
* // Some of the are also available in the context menu and toolbar of the JKQTPlotter
* // others are not
* QMenu* menuPlot=menuBar()->addMenu("Plot-Menu");
* menuPlot->addAction(plot->getPlotter()->getActionPrint());
* QMenu* menuPlotS=menuPlot->addMenu("Save ...");
* menuPlotS->addAction(plot->getPlotter()->getActionSaveData());
* menuPlotS->addAction(plot->getPlotter()->getActionSavePDF()); // not available from JKQTPlotter by default
* menuPlotS->addAction(plot->getPlotter()->getActionSavePlot());
* \endcode
* </li>
* </ol>
* \see \ref JKQTPlotterUserInteraction
*
*
*
* \subsection JKQTPLOTTER_USERMOUSEINTERACTION Mouse-Interaction in JKQTPlotter
*
* This section summarizes all user-interaction functions in JKQTPlotter that somehow relate to the mouse.
* These are:
* - \ref JKQTPLOTTER_USERMOUSEINTERACTION_MOUSEDRAG
* - \ref JKQTPLOTTER_USERMOUSEINTERACTION_MOUSECLICK
* - \ref JKQTPLOTTER_USERMOUSEINTERACTION_MOUSEWHEEL
* - \ref JKQTPLOTTER_USERMOUSEINTERACTION_MOUSEMOVE
* .
*
* \note Zooming and Paning interactions apply to both axes when they are performed with the mouse
* inside the plot. They are limited to one of the two axes, when the mouse hovers over that axis
* (e.g. when you zoom by mouse-wheel while the mouse pointer is below the plot, over the x-axis,
* only the x-axis is affected by the operation).
*
* \subsubsection JKQTPLOTTER_USERMOUSEINTERACTION_MOUSEDRAG Actions When Dragging the Mouse
* JKQTPlotter offers several methods that allow to customize, how it reacts to mouse actions:
* - registerMouseDragAction() tells JKQTPlotter to perform a certain action (selected from JKQTPlotter::MouseActionMode)
* when a specified mouse button is pushed while a specified (or no) keyborad modifiers (e.g. CTRL,ALT,SHIFT...) is pressed.
* By default JKQTPlotter calls these two registers in its constructors:
* \code
* registerMouseDragAction(Qt::LeftButton, Qt::NoModifier, JKQTPlotter::MouseActionMode::jkqtpmdaZoomByRectangle);
* registerMouseDragAction(Qt::LeftButton, Qt::ControlModifier, JKQTPlotter::MouseActionMode::jkqtpmdaPanPlotOnMove);
* \endcode
* Therefore by default you can draw a zoom rectangle with the left mouse button without modifiers
* and you can pan/drag the plot with the left mouse-button while keeping CTRL pressed.
* - deregisterMouseDragAction() deletes a previously defined user-interaction
* - clearAllRegisteredMouseDragActions() deletes all previously specified user-actions
* .
*
* Pressing the \c ESC key will stop the current JKQTPlotter::MouseActionMode.
*
* If e.g. the mode JKQTPlotter::MouseActionMode::jkqtpmdaZoomByRectangle is selected, while you drag the mouse, the
* zoom rectangle is drawn over the plot. You can modify the style of drawing using these functions:
* - setUserActionOverlayPen() sets the pen for (semi-transparent) overlay shapes, e.g. zoom rectangles
* - setUserActionOverlayBrush() sets the brush for (semi-transparent) overlay shapes, e.g. zoom rectangles
* - setUserActionOpaquePen() sets the pen for opaque overlay shapes, e.g. tool-tips
* - setUserActionOpaqueBrush() sets the brush for opaque overlay shapes, e.g. tool-tips
* - setUserActionMarkerPen() sets the pen for marker overlay shapes, e.g. with tool-tips
* - setUserActionMarkerBrush() sets the brush for marker overlay shapes, e.g. with tool-tips
* - setUserActionMarkerDiameter() sets the size of user-action markers
* - setUserActionMarkerType() sets the type of user-action markers
* .
*
* \image html zoomin_mouse_contextmenu.gif "Zooming with the mouse"
*
* \image html draw_rectangle.gif "Draw Rectangle User-Action"
*
* \image html drag_viewport.gif "Drag the Plot Viewport"
*
* \image html rulertool.gif "Measurement Ruler Tool"
*
* \image html tooltiptool.gif "Data Point Tooltip Tool"
*
*
* \subsubsection JKQTPLOTTER_USERMOUSEINTERACTION_MOUSECLICK Actions After (Double-)Clicks on the Mouse Buttons
* The right mouse button has a special role: If it is single-clicked and no JKQTPlotter::MouseActionMode is specified
* for the vent, it opens the context menu, unless you call \c setContextMenuMode(jkqtpcmmNoContextMenu) .
* You can also use setContextMenuMode() to specify which type of context menu is shown. See JKQTPContextMenuModes
* for details on the available modes.
*
* For any mouse-click, one of the following signals is emitted:
* - plotMouseClicked() for any single-click (during the pressDown-Event!)
* - plotMouseDoubleClicked() for any double-click
* .
*
* The reaction to double-clicks of the mouse buttons can be specified separately. The possible
* actions are listed in JKQTPMouseDoubleClickActions. You can bind one of these actions
* to a specific click with these functions:
* - registerMouseDoubleClickAction() tells JKQTPlotter to perform a certain action (selected from JKQTPMouseDoubleClickActions)
* when a specified mouse button is pushed while a specified (or no) keyborad modifiers (e.g. CTRL,ALT,SHIFT...) is pressed.
* By default JKQTPlotter calls this in its constructors:
* \code
* registerMouseDoubleClickAction(Qt::LeftButton, Qt::NoModifier, JKQTPMouseDoubleClickActions::jkqtpdcaClickMovesViewport);
* \endcode
* Therefore by default you can pan the plot/move the viewport by double clicking a location
* - deregisterMouseDoubleClickAction() deletes a previously defined user-interaction
* - clearAllRegisteredMouseDoubleClickAction() deletes all previously specified user-actions
* .
* The button to react to is specified as a parameter.
*
* \image html contextmenu_graphvisibility.gif
*
* \subsubsection JKQTPLOTTER_USERMOUSEINTERACTION_MOUSEWHEEL Actions When a Mouse Wheel Event Occurs
* The actions to be performed when the mouse hweel is operated are specified in JKQTPMouseWheelActions.
* You can bind one of these actions to the mouse-wheel (under the condition that a specified Qt::KeyboardModifiers
* is pressed) by using these functions:
* - registerMouseWheelAction() tells JKQTPlotter to perform a certain action (selected from JKQTPMouseWheelActions)
* when a specified mouse button is pushed while a specified (or no) keyborad modifiers (e.g. CTRL,ALT,SHIFT...) is pressed.
* By default JKQTPlotter calls this in its constructors:
* \code
* registerMouseWheelAction(Qt::NoModifier, JKQTPMouseWheelActions::jkqtpmwaZoomByWheel);
* \endcode
* Therefore by default you can zoom into and out of the plot, using the mouse wheel.
* - deregisterMouseWheelAction() deletes a previously defined user-interaction
* - clearAllMouseWheelActions() deletes all previously specified user-actions
* .
* In addition the signal void plotMouseWheelOperated() is emitted whenever a mouse-wheel event occurs.
*
*
* \subsubsection JKQTPLOTTER_USERMOUSEINTERACTION_MOUSEMOVE Signaling When Mouse Moves
* In addition the signal plotMouseMove() is called whenever the mouse moves over the plot.
* Additional signals may be emitted, depending on the currently active JKQTPlotter::MouseActionMode.
*
* Also the current mouse position is shown above the graph by default (can be switched on or off
* using setMousePositionShown() ).
*
* \image html mousepositiondisplay.gif
*
*
* \subsubsection JKQTPLOTTER_USERMOUSEINTERACTION_FASTRESIZING Fast Resizing of a Plot Widget
* When the user resized the widget, the graph would in principle have to be readrawn for every intermediate step.
* As this is very timeconsuming, JKQTPlotter uses a different approach: Actual Redrawing is delayed a few 100ms
* and this delay is reset whenever the widget size changes. Only after the last delay expires, the plot is redrawn.
* In between an image of the last state of the plot is simple stretched/compressed to fill the new/current
* widget size. In sum this looks like this:
*
* \image html jkqtplotter_fastresizing.gif
*
*
*
*
* \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="http://doc.qt.io/archives/qt-4.8/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

This function allows two plotters to draw a graph with exactly the same height or width
as in another graph. For example if you want to have two plotters which are positioned one
above the other (and have the same widget widths, which could be guaranteed by a QLayout)
you may want to make sure that their plotWidth s are always the same. In this case call
\code plotter2->synchronizeToMaster(plotter1, sdXAxis, true) \endcode of the lower plotter \c plotter2 .
