Using Bound Data Without Spreadsheet

[Bryan Bennett]

I am using the ActiveX interface to OWC 10 to create graphs in my
application. I can use SetData to place series on a chart, but this method
seems to be quite slow in updating large amounts of data. I can use a
spreadsheet to bind the data and that drastically improves the speed, but I
would like to bind the data to a local memory array as I do when using a
literal bind. Is there a way to use SetData and chDataBound to point to my
own memory array so that the chart will update automatically when I change
the data in the memory array?

I'm using C/C++ and I did find that I have to use global memory instead of
class memory so that the callbacks can access the pointers properly, but
when I try using chDataBound instead of chDataLiteral, the series don't
update when I change the memory. Thanks for any help anyone can provide.

The only way to have Chartspace dynamicly update/refresh the data is to store the data in either a Spreadsheet control or on a server. If that is not an option then you can use literal data. This will require you to set the data everytime the data is changed
