Link series to the custom data source

I wonder if there is a way to provide data for series from custom source, say, C++ vector? I have data containers in my framework, which provide random point access, minimax calculation, etc. So far, I have to copy data from containers to series XY lists, which is quite waste of memory and CPU.

Re: Transparent TBItmap becomes non-transparent in GDI+ mode

For some reason, when I install both VCL and FMX Tee packages, my C++ Builder refuses to "see" FMX TChart in palette and form designer (I mentioned this in e...

Re: Transparent TBItmap becomes non-transparent in GDI+ mode

I've attached test project for case study. It (tries to) generate CIE 1931 xyz chart with colour 'horse foot' behind it. The 'horse foot' is dynamically generated dib, which uses black as transparent key colour. It's being drawn OK in GDI mode, but becomes opaque in GDI+ mode. This code is from the ...

Re: TeeChart FMX Pro FullSource Installation - TChart is missing

Yep, I thoroughly tried to find where TChart design time has gone, or at least, tried to understand what is going on, but no luck, alas. Here is what is filtered in IDE ToolPalette for FMX, when typing "tchart": tchart2.jpg Another obvious sign that design time component is missing - existing projec...

Re: TeeChart VCL/FMX for XE4 BETA installers published

Hello.
We've found two minor issues during new FMX beta evaluation.
1) Axis label's text got clipped sometimes (see image #1)
2) Point coordinates conversion between world and canvas are wrong when dealing with lines with negative first derivative (see image #2, zipped test project attached)
