Can I change the chart type?

In the Edit screen you can change the chart by changing the chart type in the properties of the result. If you want to change the chart during a presentation you can use the icons at the bottom of the screen or you can press the keys V (vertical), H (Horizontal), L (line) or P (Pie). In version 4.x you should use the V, H, L and P keys in combination with the Shift Key!
