Is there a 'chart control' that allows a user to change the trace shape dynamically?

Hi.

I'm looking for a chart that can be initalised with a default trace but then allows the user to update the trace shape. Ultimately I need to output the trace as a best fit polynomial also. Any ideas?

Thanks.

WillA,

there is already the option to change the "interpolation"-type of the plot during runtime. But this will not include a polynominal fit.
The reason is, that graphs always plot "per point"; you can deside how to connect these points, but you will always pass directly through them if you "follow the graphplot". A polynominal fit means that the graphplot would pass by points without touching them. If you want to have such a functionality, you have therefore to implement it on your own using the appropriate mathematical functions.

hope this helps,
Norbert
