Hi
It's finally done. I merged the code paths of the Bar and XY-point charts.
This resulted in a more compact and robust code base.
I also completed support for the secondary Y axis.

I would be happy if someone would like to test the binaries.

I didn't enable exception handling to see if there were any problems.
The full source is uploaded to github.
You can interact with the diagrams in the following ways:
- Left button mouse drag: pans the series associated with the primary Y axis
- Right button mouse drag: pans the series associated with the secondary Y axis
- Left button mouse drag + Ctrl Key: zooms the series associated with the primary Y axis
- Right button mouse drag + Ctrl Key: zooms the series associated with the secondary Y axis
- Double click on an axis + Ctrl Key: reset the axis using the automatic scale values
- Double click on any element of the chart: opens the setup dialog on the corresponding Tab
- Gestures: zoom and pan enabled
