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. If T...

Sorry for bloated example, guys :) Ripped it from the working project. I will try to make simple project, but it'll take time. Let me explain. 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...

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 ...

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...

Hello. I'm running C++ Builder Architect XE4 IDE, version 18.0.4854.59655. When instaling full source TeeChart Pro package released on May 21, 2013, Build 2013.08.130521, TChart component is missing from design palette for FMX application. TChart3D is there, though. Strangely enough, TChart icon is ...

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)
