I try to increase Z axis size at my 3d bar chart. I use jfreechart at version 1.0.19, and can't find proper method to do this. Any ideas?
To alter the faux depth, you can adjust the offset parameters in your BarRenderer3D
constructor, for example:
BarRenderer3D r = new BarRenderer3D(
3 * BarRenderer3D.DEFAULT_X_OFFSET / 2,
3 * BarRenderer3D.DEFAULT_Y_OFFSET / 2);
categoryPlot.setRenderer(r);
To adjust the category label position and font size, use the approaches shown in JFreeChart Bar Graph Labels. See also Migration from JFreeChart 1.0.x regarding 3D charts.
