Using ActiveX TeeChart with Delphi7 ?

I need to have my TeeCharts show chinese characters. However, I only have the VCL version of TeeChart (no Unicode support!!!!!!!

).
I am using Delphi7. Can I use the ActiveX TeeChart components in Delphi 7 ?
If I was to purchase the ActiveX version, would there be any problems or incompatibilities if I swapped over?

Hi RodneyB,

TeeChart Pro ActiveX should work fine in Delphi as it is a standard OCX control. However we don't support TeeChart Pro ActiveX version in VCL environments since we already have TeeChart VCL versions for them.

However, once you have the ActiveX version working in one of those IDEs we may help you on how TeeChart ActiveX version works.

Regarding VCL version and unicode support, in v8, the version we are currently working in, we have implemented a method to display unicode text directly to TChart's canvas. We haven't tested the ActiveX version in VCL environments for displaying unicode characters but it should work fine.

I can already write Chinese to TeeChart's DelphiCanvas, but that is a far cry from writing unicode strings to the chart's title, or to a TChartSeries.AddXY(...label...). Will v8 be able to do this or just simply allow the user to write unicode to the DelphiCanvas?

Also, any idea when v8 will be available?

Thanks.

For now, only methods for drawing unicode characters in the chart's canvas will be provided.

We'd like to make v8 release to coincide with the release of CodeGear RAD Studio for C++ 2007, (which might be in few weeks).
