Detailed Description

This implements a single vertical (notched) boxplot as a "geometric element", where the data is directly given to the object and not stored in a column, as in JKQTPBoxplotVerticalGraph.

the x position is given in posColumn. All other data are given in the median, min, max, percentile25 and percentile75.

The different features of a boxplot are:

The example Example (JKQTPlotter): Styling different aspects of boxplots discusses different options to style boxplots:

Member Function Documentation

◆ draw()

virtual void JKQTPBoxplotVerticalElement::draw ( JKQTPEnhancedPainter painter)
overridevirtual

plots the graph to the plotter object specified as parent

Implements JKQTPPlotElement.

◆ drawKeyMarker()

virtual void JKQTPBoxplotVerticalElement::drawKeyMarker ( JKQTPEnhancedPainter painter,
const QRectF &  rect 
)
overridevirtual

plots a key marker inside the specified rectangle rect

Implements JKQTPPlotElement.

◆ getXMinMax()

virtual bool JKQTPBoxplotVerticalElement::getXMinMax ( double &  minx,
double &  maxx,
double &  smallestGreaterZero 
)
overridevirtual

get the maximum and minimum x-value of the graph

The result is given in the two parameters which are call-by-reference parameters!

Parameters
[out]minxminimal x-value used in the graph
[out]maxxmaximal x-value used in the graph
[out]smallestGreaterZerothe smalles x-value in the graph, which is larger than 0 (this is used in auto-sizing for logarithmic axes)
Returns
true on success, i.e. if there were datapoints in the plot, or false on failure (e.g. when the graph is empty)

Implements JKQTPPlotElement.

◆ getYMinMax()

virtual bool JKQTPBoxplotVerticalElement::getYMinMax ( double &  miny,
double &  maxy,
double &  smallestGreaterZero 
)
overridevirtual

get the maximum and minimum y-value of the graph

The result is given in the two parameters which are call-by-reference parameters!

Parameters
[out]minyminimal y-value used in the graph
[out]maxymaximal y-value used in the graph
[out]smallestGreaterZerothe smalles y-value in the graph, which is larger than 0 (this is used in auto-sizing for logarithmic axes)
Returns
true on success, i.e. if there were datapoints in the plot, or false on failure (e.g. when the graph is empty)

Implements JKQTPPlotElement.
