Hello,
after installation of the latest TeeChart FMX from souces, via the TeeRecompile.exe TChart is diabled for the 64Bit iOS platform.

Is that done on purpose, because there are problems ?
best regards and thanks

Hello X-Ray,
If your application targets an iOS 64-bit device, TChart is still available there and builds correctly. You need an iOS 64-bit device to run it though. Did TeeRecompile run fine for iOS 64-bit device? Does this work for you?

I have an iPhone 6 and other components are enabled for the 64Bit iOS platform.
Also the TeeRecompile did run fine for the 64Bit iOS platform.
There is actually more trouble, that is why I am asking. I also have a multi device application that contains a TChart and that now crashes on startup when compiled for 64Bit iOS. I could somehow connect the crash to TChart. Finally I was able to create an iOS 64bit app that just contains a design time TChart and nothing else and that crashes too on startup. I have attached the small project.

Hi X-Ray,
Thanks for the info. I could reproduce the problem here and we will investigate it. We will get back to you when we have further news.

This has been fixed for the following maintenance release.

A simple design-time app works fine for us here. However, your app crashes and added the problem to bugzilla (
bug #1238).

Hi Narcis,
I just created a new/fresh multi device application and put instances of a TChart, a TSurfaceSeries, a TColorGridSeries and a TTeeCommander on the empty form. When I try to run the 64-bit version on my iPhone6 it crashes too on startup. So this is a showstopper on iOS. Please let me know of any workaround to get this running.
best regards

Hello,
The problem is TeeCommander. Following the steps you mentioned without a TTeeCommander component works fine.

Hi Narcis,
yes indeed, now that I removed TeeCommander the 64-bit app starts up fine.
Do you have a quick example how to set the TChart in rotation or zoom mode by a button click without usage of the TeeCommander component ?
best regards

Hi X-Ray,
Yes, this can be done like this:
Code: Select all
procedure TForm1.RotateBtnClick(Sender: TObject);
begin
Chart1.Aspect.Orthogonal:=False;
Chart1.Aspect.Rotation:=15;
Chart1.Aspect.Elevation:=300;
end;
procedure TForm1.ZoomBtnClick(Sender: TObject);
begin
Chart1.Aspect.Zoom:=60;
end;
You could use slider controls to modify those values as well.

Hi Narcis,
But how do I set the Chart into the zoom or rotate mode, so that it can be zoomed or rotated by the touch and dragging with a finger ?
You are just setting the rotation angle and the zoom % by code in that example, right?
best regards,
Thomas

Yes, exactly.

You should use the gesturing functionality in Delphi as explained in those articles:
http://docwiki.embarcadero.com/RADStudi ... g_Overview
http://docwiki.embarcadero.com/CodeExam ... s_(Delphi)
I'm also attaching a practical gestures example with TeeChart.

Hi Narcis,
Thank you, the Gestures example was very helpful !

Hi X-Ray,
You're very welcome. I'm glad to hear that. It actually inspired a
blog post about Delphi gestures with TeeChart.

Hello,
there are problems with axes titles in 3D that got worse with the latest release 2015.16:
- Foto 08.09.15 11 36 51.png (131.62 KiB) Viewed 33761 times
I used the gesture example and added titles for the X-Axis (Bottom Axis), Y-Axis (Left Axis) and the Z-Axis (Depth Axis). What you see is (on a iPhone 6):
1) The titles are not aligned with the axis labels (This works well in the VCL version)
2) The distance between the axis labels and the axis title is too short (how can I change this ?)
3) The Z-Axis title has disappeared or is somewhere far away
Are there any fixes for this ?
best regards,
X-ray

I've tried it with v2015.15 and v2015.16 in Android and it seems to give the same result. Could you please specify what two versions to compare?

I get the same result with VCL:

I'm afraid this is not possible.
Instead, you could draw your title or text manually. Ie:
Code: Select all
procedure TForm1.Chart1BeforeDrawSeries(Sender: TObject);
var yOffset, tmpZ, tmpW: Integer;
pos: TPointF;
st: string;
begin
yOffset:=10;
with Chart1.Axes.Bottom do
begin
st:=Title.Caption;
Chart1.Canvas.AssignFont(Title.Font);
tmpW:=Chart1.Canvas.TextWidth(st);
pos.X:=IStartPos + ((IEndPos-IStartPos) div 2);// - (tmpW div 2);
pos.Y:=Round(Chart1.Axes.Left.IEndPos + Abs(LabelsFont.Size) + TickLength + 7);
tmpZ:=Round(Chart1.Width3D * ZPosition * 0.01);
end;
pos:=Chart1.Canvas.Calculate3DPosition(pos,tmpZ);
pos.Y:=pos.Y+yOffset;
Chart1.Canvas.TextOut(pos.X, pos.Y, st);
end;

The depth axis is not visible. It will appear if you make it visible:
