Detailed Description

This implements a single vertical Violin Plot as a "geometric element".

Draws a vertical violin plot in one of the following styles:

This graph/plot element represents a single such plot. Its center is positioned at an x-coordinate provided by setPos(). The width of the full plot (left+right!) is given by JKQTPGraphViolinplotStyleMixin::setViolinWidthAbsolute().

The data is represented partly by single values (e.g. setMedian(), setMin(), ...) and partly by the two columns set with setViolinPositionColumn() and setViolinFrequencyColumn(). The latter two represent a density estimate (or histogram) of the distribution represented by this plot, which is evaluated at the y-positions from setViolinPositionColumn(). For each such y-position a (not necessarily normalized) frequency is given by the values in setViolinFrequencyColumn().

Member Function Documentation

draw()

virtual void JKQTPViolinplotVerticalElement::draw ( JKQTPEnhancedPainter &  painter )

overridevirtual

plots the graph to the plotter object specified as parent

Implements JKQTPPlotElement.

drawKeyMarker()

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

overridevirtual

plots a key marker inside the specified rectangle rect

Implements JKQTPPlotElement.

getXMinMax()

virtual bool JKQTPViolinplotVerticalElement::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 JKQTPViolinplotVerticalElement::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.
