Axis Ranges

[kapibara]

For the Multiple Panes example, we wrote in the wiki that either one of Axis.Range or Axis.Marks.Range is sufficient for displaying the side axismarks of each pane correctly. However, it seems both are needed to be set? Run the demo and unselect Axis.Range or Axis.Marks.Range and you'll see what I mean. Am I missing something?

Also, using a ListChartSource with real data instead of RandomChartSource seems to mess up one of the two left axises, see pic below. Select "real data" in the demo and the upper pane will have such overlapping marks.

There is also a TChartAxis.Marks.AtDataOnly. When this is set to true for both y axes the reported issues go away. Added this to the wiki.

Don't know why the Chart.Extent is switched to be fixed in the tutorial (I did not write that...)

Thanks wp, it worked.

Good to know that Chart.Extent is not needed for paned charts to work.
