There are several options for customising bar charts:
All bar charts can be made three-dimensional by selecting the 3-D option when you create the chart. You can edit the pitch and roll of 3-D charts using the Chart dialogue box from the menu accessed from the menu.
Enter the pitch and roll in degrees. This will change the viewing angle of the 3-D chart.
You can customise the position of bars in the chart using the Bar dialogue box.
These options are set to zero by default: type in a value between 1 and 100 to activate them.
