Note: Here we use the functions `JKQTPBarVerticalGraph::setXColumn()` and `JKQTPBarVerticalGraph::setYColumn()` to set the columns to use for the stack positions (X) and heights (Y). Instead you can also use the semantic version `JKQTPBarGraphBase::setBarPositionColumn()` and `JKQTPBarGraphBase::setBarHeightColumn()`.
The result looks like this: The result looks like this:

In order to draw horizontal error bars, you have to use `JKQTPBarHorizontalGraph` instead of `JKQTPBarVerticalGraph`:

/** \brief This is a base-class for all bar graphs with vertical or horizontal orientation (the orientation is implemented in dervied classes!)
* \ingroup jkqtplotter_barssticks
*
* This class plots a bargraph. This image explains the parameters:
*
* \image html bargraph_basics.png
*
* By default the sift parameter is, so the bar is centered at the x-value. The width is 0.9,
* so adjacent bars are plotted with a small distance between them. It is possible to use these two parameters
* to plot multiple bars for every x-value, by having on JKQTPSpecialLineHorizontalGraph object per
* set of bars that belong together. For example for three bars per x-value one would set:
* \verbatim
* width=0.3
* shift=-0.3 / 0 / +0.3
* \endverbatim
* This results in a bargraph, as shown here:
