Are Teechart (including series) threadsafe?
Is there any samples for that?

I want to handle teechart with sth. time spending in the boost::thread ..

Hello,

No, TeeChart isn't thread safe.
See this reply:

Also note the "Multi-CPU Parallel Threads" section in the What's New page.

Thank you.
So you mean that it is OK if handling Teechart(including series) in one thread(not only the main thread)
as following.

Code: Select all

Chart1->AutoPaint = false;
//Do sth. with Teechart and Series
Chart1->AutoPaint = true;
Chart1->Repaint();

But when I add data two TFastLineseries, some AV error like attachment arose.

If I mask "Series->Add ", it seems OK..
What is d2d1.dll, is it a part of Teechart?

[elmec]

Further information, I replaced Add() with AddArray(), the error didn't arise...

Yes, this should be the way.

We'd need a simple example project we can run as-is to reproduce the problem here to further investigate this.

No, it isn't.

Both Add() and AddArray() call the same AddXY function. The only difference is that AddArray() calls BeginUpdate() before adding the values and EndUpdate() when finished.
So you could try with:

Code: Select all

Series->BeginUpdate;
Series->Add(yourValue);
Series->EndUpdate;
