Re: About the behavior of TScrollPager

I am sorry , pls ignore Question4..
And for Question 1, before assigning series to TScrollPager,
the series should have a parentchart..so the code should be as following.

Code: Select all

TFastLineSeries* seriesTest = new TFastLineSeries(this);
seriesTest->ParentChart = Chart1;
ScrollPager->Series = seriesTest;

Re: About the behavior of TScrollPager

Question4:
We know that there are two series when I assign a Series (seriesTest) to TScrollPager,
one is in the TChart, and another is in the ScrollPager->SubChartTChart.
The two series just have a pointer to seriesTest?
Or the one in the TChart also has a copy of seriesTest?

Re: response slowly when remove series from lots of series

I tried to set AutoRepaint to false, and the DialogBox showed instantly. Off course, too repaint the TChart, we still need to call Repaint() func, then it block the main thread for about 2 seconds here..nothing changed! So maybe I need a thread to repaint the TChart? I don't know why it is so slow. ...

Re: response slowly when remove series from lots of series

BTW, I am using Teechart2014 for C++ Builder XE4 HD App.
I think the delay duration until DialogBox show
should be that main thread is waiting teechart automatic repaiting after series removed..

Can you reproduce with the EXE I have sent to you?
Is there any idea to improve that?
