This is actually a question concerning QCChart 3D for .NET, but I can't make a new topic there. Hopefully it is ok to post here.
We need to be able to render scatter plots with large volumes of points (at least 100K. 1000K would be nice.) I ran a few brief experiments to test the performance at 100K and the performance was not what we would like.
Do you have any advice on how to get that kind of performance out of a scatter plot?
On a related note, we would also like to be able to dynamically update the plot in response to changes in the data. From what I can tell from your examples, this would require a redraw after every data change, which is not desirable give the performance issues mentioned above.
Do you have any suggestions on how to manage updates more efficiently?
Thanks
