Random data when more than 33 series are in a graph

Hi,

When I specify a datasource with more than 33 fields (series), chartFX

randomly ignores the columns after the 33rd column, I.e. If I have 60

columns chartFX will display all of the first 33 and then any number of

random columns from the last 30. This only happens when I specify CDT_VALUE

and CDT_LABEL for the columns:

*-- Code

FOR lnC = 1 to lnF - 1

thisform.pageframe1.page1.olecontrol1.datatype[lnC] = CDT_VALUE

NEXT lnC

thisform.pageframe1.page1.olecontrol1.DataType[lnFieldsInCursor] = CDT_LABEL

*-- /Code

If I don't specify these styles (which I need to do anyway, but if I

don't....) it will display all columns fine.

I am using ChartFX Client Server Version 4.0.19.

I have a complete sample form if someone wants to see it with their own

eyes. (In VFP 7)

Has anybody seen this before? Does anybody know how to fix it?

Cheers,

Chris.

This is a limitation. Only 32 Columns can be used in data-binding, if you

data has more you will need to use alternate methods of passing data such as

OpenDataEx-CloseData.

Notice that there is no difference in the performance. You will just need to

write a little bit more of code.

Thanks for that information. Is this problem documented anywhere? and Is

there any particular reason why the control doesn't just give an error

instead of trying to show random data?

Thanks anyway for your fast answer,

Chris.
