I have two problems:

1) The colors for the series' square waves are not carried over to the pdf file. Each of the five square waves are BLACK rather than the colors designated. The GUI shows the colors fine.

2) After zooming, a small part of each series' plot is printed past the point where the horizontal axis ends. The plot continues a little way even though there is no more x axis for the series to be plotted on. Again, the GUI zooms fine.

Hi.

The first problem looks like a bug to me (pdf Canvas is not able to set current pen properties). But I was not able to replicate it here using the latest TeeChart (VCL) version.

The second problem is more a missing feature. Clipping in PDF Canvas is not yet supported. To be more precise, the internal ClipRectangle and UnClip methods do not work in all cases. We'll try to improve this in next major teeChart release.

I have V6 ActiveX TeeChart control, and I have the same problem -- pen properties are not being carried over to the pdf Canvas.

Is this a confirmed bug in the ActiveX control? How can I get a fix? Does V7 have the fix?

Thanks.

Hi Paul,

yes, a confirmed bug. It also happens with the latest v7.03. You will only get a correct results when the width of the line series is set to 1 (default). It's already on our defect list and a fix for it will be considered to inclusion for the next maintenance releases.

Using latest TeeChart ActiveX (v8.0.0.8.10301).

v6, v7 now v8. Looks like "pen properties are not being carried over to the pdf Canvas" is a perpetual bug.
Is this on a current defect list or you guys give up?

Hi adim,

Yes, this is still on the bug list to be investigated with ID. number TV52014346.
