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>secondary coordinate axis</b> you can add additional secondary x- and y-axes to a plot, which are shown stacked, beside the plot.
|
|
<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.
