TChartGrid

Hi,

TChart 7.04
I'm using a ChartGrid, connected to a Chart --> Series1.
Series1.FillSampleValues(20);
So far so good.

However, when I click on the ChartGrid and hold down the DOWN KEY,
the ChartGrid starts scrolling beyond the size of the Series1, i.e. points (zeroos) are appended to the Series1.

Is there a trick too avoid this? My customer wants to have the ability to scroll down in the ChartGrid from start to end, but no automatic increase of the tracesize. (The mousewheel does NOT has this behaviour.)

Many thanks in advance for your help!

By the way, my previous question with dotted lines is solved by using fastline instead of normal series. Thanks!

Kind regards,

Davy

Yes, you can disable this by setting the goEditing option to False.

Thanks for the advise. !

Hi Pep,

To be more complete:
ChartGrid1.OnKeyDown if Key = VK_DOWN --> - GoEditing
ChartGrid1.OnKeyUp if Key = VK_DOWN --> + GoEditing

However, do you publish a list when upgrading the product, describing changes on undocumented features like this one or dotted line series?
