Extent of date x-axis
lazarus / 55-TAChart

I have a chart with dates as x-axis. The chart is on a form and it
looks perfect when shown the first time (see first attachment). When I
paint the chart on a print preview form using the PaintOnCanvas
procedure, the minimum and maximum on the x-axis are shifted, see
second attatchment. When the chart is drawn on the form again, the
same happens.

I use the extent property of the chart to set the minimum and maximum
values, but that has no effect. I tried the same with the
ExtentSizeLimit property and the Range property of the axis. No
effect. Is this a bug, or have I forgotten something?

Kubuntu 12.04 64 bits.

Adrie, does the fix work for you?
