hello,
I'm testing using teechart in an iPhone app. I'm using Delphi XE2 update 4 & the last source code for tee chart.
My test code is very simple:

procedure TForm1.FormCreate(Sender: TObject);
begin
Series1.FillSampleValues(5);
end;

The attached screenshot show the obtained chart in the iOS Simulator.
What are the 4 shadow rectangles ? the Marks shadow ?

Whatever the series type used I got a line staring from letdown corner !!!
Any experience with iOS firemonkey version?
Any demo for teechart on the app store ?
Is the dot net version is working better than the firemonkey version under iOS ?
Kind regards

Hi,
Teechart draws an unwanted line even without having any series.
May be it's an axis drawing issue !!

Hi Yazou,

As you'll read here, there are some known problems in the iOS emulator/simulator. This would probably explain the displacement of the marks shadows.

That line being drawn in the chart could be different. However, if I'm not wrong this only happens in the emulator/simulator. Does it happen for you in a real device too?

hello Yeray,
On my device (iPhone 3GS) i got the same results (see the attached screenshot of my device).
in the post of X-ray he says that teechart is working well !!

Do you have a good back of customer using the dot net version with iOS ?
My main application is C++ and I need some UI and charting. I'm evaluating some possible choices :
Firemonkey with Teechart
Monotouch with teechart dot net
writing my own charting function in objective-C and C++ starting from open source OpenGL plotting library .

BTW, I tested free pascal directly from Xcode without the Firemonkey SDK. It works great and the UI is really iOS native.

Do you have any plan to port Teechart using cocoaPas (the object pascal wrapper of the Cocoa framework) ?
I think that a native cocoa teechart version has a great market potential

Kind regards,
