This implements a horizontal bar graph with bars between
This class draws horizontal bargraphs. The basic properties are defined and documented with JKQTPBarGraphBase .
The a horizontal is defined by a series of datapoints (y,x=f(y)) . Bars are then drawn fromm a baseline (often =0 ) to the value x=f(y) at each position y. Thus the class is derived from JKQTPXYBaselineGraph, which provides a baseline as well as columns for x and y values.

overrideprotectedvirtual |
this function is used by autoscaleBarWidthAndShift() to determine whether a given graph shall be taken into account when autoscaling. Typically this returns true for all JKQTPBarGraphBase-derved objects with the same orientation (horizontal or vertical)
Implements JKQTPBarGraphBase.
|
overridevirtual |
plots the graph to the plotter object specified as parent
Implements JKQTPPlotElement.
|
overridevirtual |
returns the column used as "key" for the current graph (typically this call getXColumn(), but for horizontal graphs like filled curves or barcharts it may call getYColumn() )
Reimplemented from JKQTPXYGraph.
|
overridevirtual |
returns the column used as "value" for the current graph (typically this call getXColumn(), but for horizontal graphs like filled curves or barcharts it may call getYColumn() )
Reimplemented from JKQTPXYGraph.

get the maximum and minimum x-value of the graph
The result is given in the two parameters which are call-by-reference 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) |
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 JKQTPXYGraph.
Reimplemented in JKQTPBarHorizontalErrorGraph.

The result is given in the two parameters which are call-by-reference parameters!

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 JKQTPXYGraph.
