The problems are all of version 2014 . // Bug 1 About this bug, I have mentioned before. ScrollPager->ColorBandTool->StartValue = 500; ScrollPager->ColorBandTool->EndValue = 600; // Without the line below, the position set of ColorBandTool above not work! Chart1->BottomAxis->SetMinMax(500, 600); // ...

When there are many data(about one million) in ScrollPager->Series,
the dragging speed of ColorBandTool falls obviously...
Even the series is TFastlineSeries, and I have set it with "Speed Theme" like mentioned in the Examples.

Is there any good way to avoid that...

Thanks in advance.

Thank you !
So is it a bug?

BTW, I am using the newest version for Firemonkey (201309)

If I add some code like below...
when I clicked the Button1, it seems working well...

Failed to change the offset of CursorLine Tool by following code.. cursorLine->Snap = true; cursorLine->Series = Series1; Series1->Add(1.0); Series1->Add(2.0); Series1->Add(3.0); // Try to change the Y axis offset of Curorline to 2.0, // but failed. cursorLine->YValue = 2.0; CursorLine.png

Thanks,
I'll try it and tell you the result.

Hello, Thanks for your advice. But would you please tell us how to fix the Marks problem. We cannt wait for the next release. So I have tried to use the following code to modify mark manually. SeriesMark->Marks->Item[3]->Text->Text = "N"; But it didn't work well... Here you're correct, this is a bug...

Hello,

We know could be used to change some label text.
but is there a property like used to change the label text color?

Thanks in advance.

So what should I do ?

Just pass the (data size - 1) instead of the data size ?
Is there any side effect?

Then, what is the below one in FMXTee.Engine.hpp?
