Re: Very long canvas - print fail
Hello, The metafiles don't seem to have saved correctly in the zip you posted, but we'll take another look at this to see if we can shed any light. With the current version of TeeChart the plot cuts the last data points in the metafile at exactly 32,767 pixels, the known limit for a metafile. The ca...

Hello,
It shouldn't be necessary to uninstall Framework 4.0 to install v3.5, they can run side-by-side.

Re: Transparent bands
Hello Anders, The code is very similar in Delphi. I'm not sure exactly which part you need, but bear in mind that TeeChart VCL/FMX has a Colorband tool that may be used to plot the rectangles.
