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 ...

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?

Logarithmic chart question

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...
