 width of box in percent of distance between the current two posColumn values if we only plot one box&whiskers then JKQTPGraphBoxplotStyleMixin::boxWidthAbsolute in pt is used

int medianColumn
 the column that contains the median-component of the datapoints
int medianConfidenceColumn
 the column that contains the confidence interval width of the median (e.g. 1.57*IQR/sqrt(n) ). This is used to draw a notch in the plot (if set)

Detailed Description

This implements horizontal boxplots, optionally also a notched boxplot.

the x position is given in posColumn. All other data are given in the medianColumn, minColumn, maxColumn, percentile25Column and percentile75Column.

◆ JKQTPBoxplotHorizontalGraph() [2/2]

JKQTPBoxplotHorizontalGraph::JKQTPBoxplotHorizontalGraph ( JKQTPlotter * parent)

Member Function Documentation

◆ draw()

virtual void JKQTPBoxplotHorizontalGraph::draw ( JKQTPEnhancedPainter & painter)
overridevirtual

plots the graph to the plotter object specified as parent

Implements JKQTPPlotElement.

◆ drawKeyMarker()

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

plots a key marker inside the specified rectangle rect

Implements JKQTPPlotElement.

◆ getXMinMax()

virtual bool JKQTPBoxplotHorizontalGraph::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 JKQTPBoxplotHorizontalGraph::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.
