Detailed Description

This implements a vertical bar graph with bars between and and error indicator.

This works much the same as JKQTPBarHorizontalGraph, but also draws error indicators. Here is an example output:

Error indicators are defined and styled with the functions from JKQTPYGraphErrors .

drawErrorsAfter()

virtual void JKQTPBarVerticalErrorGraph::drawErrorsAfter ( JKQTPEnhancedPainter &  painter )

overrideprotectedvirtual

this function is used to plot error inidcators before plotting the graphs.

Reimplemented from JKQTPGraph.

int JKQTPBarVerticalErrorGraph::getBarErrorColumn

(

)

const

returns the column that contains the bar height errors

getBarErrorStyle()

JKQTPErrorPlotstyle JKQTPBarVerticalErrorGraph::getBarErrorStyle

(

)

const

returns the error style of the bar

getBarErrorSymmetric()

bool JKQTPBarVerticalErrorGraph::getBarErrorSymmetric

(

)

const

returns whether the errors of the bars are symmetric

virtual bool JKQTPBarVerticalErrorGraph::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!

Reimplemented from JKQTPBarVerticalGraph.

sets the column that contains the bar height errors

setBarErrorColumn [2/2]

void JKQTPBarVerticalErrorGraph::setBarErrorColumn ( size_t  column )

slot

sets the column that contains the bar height errors

setBarErrorStyle

void JKQTPBarVerticalErrorGraph::setBarErrorStyle ( JKQTPErrorPlotstyle  __value )

slot

sets the error style of the bar

setBarErrorSymmetric

void JKQTPBarVerticalErrorGraph::setBarErrorSymmetric ( bool  __value )

slot

sets whether the errors of the bars are symmetric

setBarLowerErrorColumn [1/2]

void JKQTPBarVerticalErrorGraph::setBarLowerErrorColumn ( int  column )

slot

sets the column that contains the bar height errors

setBarLowerErrorColumn [2/2]

void JKQTPBarVerticalErrorGraph::setBarLowerErrorColumn ( size_t  column )

slot

sets the column that contains the bar height errors

usesColumn()

virtual bool JKQTPBarVerticalErrorGraph::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 JKQTPXYGraph.
