Just read this on the Whats New list of TeeChart 7: Removed limitation on number of source points to calculate smooth points. (Fixed size arrays have been converted to dynamic arrays). Warning: Smoothing more than 500 points can be a very slow operation. We have now decided to upgrade to version 7.

The number of points you can smooth properly depends on the number of source series points multiplied by the smoothing factor. For example, if I have 20 points in my source series and my smoothing factor is 4, the resulting smoothed series would consist of 80 points (20 * 4) and that works fine. If ...

We are using TeeChart 6.01 Smoothing works great when smoothing only a few points in a graph. However, in our application each series consists of more than 3200 points. We need to smooth these series lines without interpolation and a smoothing factor of 5. I have noticed that for some reason, when t...

Thanks for your help, after playing around with the sample you gave, I received the results I was looking for.

Hi Marjan, Thanks for your reply. It is importand that you see how the image looks like. Can I perhaps email it to you instead? Please have a look at it and tell me if it is possible to get a similar result. Unfortunately I don't have the TeeChart demo's source code to look at how method #2 can be p...

I'm trying to create a chart with both the X and Y axis being logarithmic based. I have tried playing around with logarithmic axis lines and custom axis lines but currently can't get the result I'm looking for. Both the X and Y axis ranges are known beforehand but the actual series line points are n...
