JKQTPColumnContourPlot::JKQTPColumnContourPlot ( JKQTPlotter parent)

class constructor

Member Function Documentation

◆ ensureImageData()

virtual void JKQTPColumnContourPlot::ensureImageData ( )
overrideprotectedvirtual

overwrite this to fill the data poiters before they are accessed (e.g. to load data from a column in the datastore

Reimplemented from JKQTPMathImageBase.

◆ getImageColumn()

int JKQTPColumnContourPlot::getImageColumn ( ) const

column containing the displayed image

◆ setImageColumn() [1/2]

void JKQTPColumnContourPlot::setImageColumn ( int  __value)

column containing the displayed image

◆ setImageColumn() [2/2]

void JKQTPColumnContourPlot::setImageColumn ( size_t  __value)

column containing the displayed image

◆ usesColumn()

virtual bool JKQTPColumnContourPlot::usesColumn ( int  c) const
overridevirtual

returns true if the given column is used by the graph

This virtual function indicates whether a given column is used by this graph. Override this function in your derived graphs to indicate to JKQTPlotter / JKQTBasePlotter , which columns from the internal JKQTPDatastore are actually used. This information can be used e.g. for graph-specific data-export.

Reimplemented from JKQTPGraph.
