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]	minx	minimal x-value used in the graph
[out]	maxx	maximal x-value used in the graph
[out]	smallestGreaterZero	the 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]	miny	minimal y-value used in the graph
[out]	maxy	maximal y-value used in the graph
[out]	smallestGreaterZero	the 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.
