Member Function Documentation

drawErrorsAfter()

virtual void JKQTPImpulsesHorizontalErrorGraph::drawErrorsAfter ( JKQTPEnhancedPainter &  painter )

overrideprotectedvirtual

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

Reimplemented from JKQTPGraph.

getErrorColumn()

int JKQTPImpulsesHorizontalErrorGraph::getErrorColumn

(

)

const

returns the column that contains the bar height errors

getErrorColumnLower()

int JKQTPImpulsesHorizontalErrorGraph::getErrorColumnLower

(

)

const

returns the column that contains the lower bar height errors

getErrorStyle()

JKQTPErrorPlotstyle JKQTPImpulsesHorizontalErrorGraph::getErrorStyle

(

)

const

returns the error style of the bar

getErrorSymmetric()

bool JKQTPImpulsesHorizontalErrorGraph::getErrorSymmetric

(

)

const

returns whether the errors of the bars are symmetric

getXMinMax()

virtual bool JKQTPImpulsesHorizontalErrorGraph::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)

Reimplemented from JKQTPImpulsesHorizontalGraph.

setErrorColumn [1/2]

void JKQTPImpulsesHorizontalErrorGraph::setErrorColumn ( int  column )

slot

sets the column that contains the bar height errors

setErrorColumn [2/2]

void JKQTPImpulsesHorizontalErrorGraph::setErrorColumn ( size_t  column )

slot

sets the column that contains the bar height errors

setErrorColumnLower [1/2]

void JKQTPImpulsesHorizontalErrorGraph::setErrorColumnLower ( int  column )

slot

sets the column that contains the bar height errors

setErrorColumnLower [2/2]

void JKQTPImpulsesHorizontalErrorGraph::setErrorColumnLower ( size_t  column )

slot

sets the column that contains the bar height errors

setErrorStyle

void JKQTPImpulsesHorizontalErrorGraph::setErrorStyle ( JKQTPErrorPlotstyle  __value )

slot

sets the error style of the bar

setErrorSymmetric

void JKQTPImpulsesHorizontalErrorGraph::setErrorSymmetric ( bool  __value )

slot

sets whether the errors of the bars are symmetric

usesColumn()

virtual bool JKQTPImpulsesHorizontalErrorGraph::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.
