Re: Marks not working as expected with TChartShapes

Hello,

Sorry for the delay with this reply.

You could set the text for the shape and leave Marks.Visible False.

eg.

Code: Select all

Series.Font.Color := clWhite;
Series.Text.Add('my text');

Re: Gradients not showing if endcolor is set

Hello Nigel, Ah, this is an FMX project. I'd assumed we we were looking at VCL. uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMXTee.Chart, FMX.Controls3D, FMXTee.Chart3D, FMXTee.Series, FMXTee.Canv...

Hello Nigel, Re. I can email you the main executable if you wish but it wont let me load it on here, but i have attached an image from the IDE with the project built and after I clicked the button. Yes, to upload the exe you could use this link. http://steema.net/uploads/ The project itself would be...

Re: Gradients not showing if endcolor is set

Hello Nigel, Do you mean that the same code you posted up initially still doesn't work for you? Default Chart name is 'Chart1', if you start a new project from scratch and drop a chart on it, this (your code) should work ok: procedure TForm14.FormCreate(Sender: TObject); begin Chart1.View3D := True;...

Re: Gradients not showing if endcolor is set

Greetings,

Your code with a new TeeChart on a new form, brings up a Chart that appears ok as per the code itself.

I'm using TeeChart Pro; I'll setup a machine with access to Standard but I wouldn't expect a difference.

Re: Crash with nearly identical X values in two TPointSeries

Hello Hans,

Your test app crashes when run as you expected. We're looking to see what may be the cause; nothing obvious yet.

Re: Chart font is way to large

Hello Ed, I assume that's a live chart on a page, not a static rendering of a Chart. I can't think straight-off what might cause that that wouldn't be general to the whole app (ie. the Windows scale that you've already checked). If you could activate an editor on that page (via double-click or simil...

Re: A new ternary graph implementation

Hello Errol, Sorry for the delay replying; I'll take a look through the information you've sent. A note on your comment: A ternary plot is simply an X-Y plot, as there are only 2 independent variables (Z is always equal to 100 - X% - Y% where X% = X/(X+Y+Z)*100 and Y% = Y/(X+Y+Z)*100. We did respond...

Re: Wind vector plot with TArrowSeries

Hello jradke, This code simplifies a how-to. Add 3 ArrowSeries to a Chart and run the code in a button. My example calculations aren't up to much, just to give an idea. Y location ArrowStart gives height above sea-level, X ArrowStart location is the timestamp and the end of each arrow would be calcu...

Re: TeeChart crash with Japanese date/number/currency settings

Hello Tero, Yes, the not crossing-boundaries should be valid. Our understanding of best practice when researching use of GDIPlus in an app that hosts a dll is to use nesting. ie. with the test code it might look something like this: CRect chart1Rect(rect); chart1Rect.DeflateRect(0, 0, rect.Width() /...

Re: TeeChart crash with Japanese date/number/currency settings

A note on this to check. GDIPlusShutdown should only be called once as it unloads the library (would also affect GDIPlus for the entire .exe). It shouldn't be unloaded if a call to GDIPlus methods is made after the call. Another question. Your comment: consider switching back to GDI rendering becaus...

Hello,

As far as we're aware, the proposed solution responds to the requirement. We do not intend to take this any further unless a note is raised on any particular aspect.

Re: TeeChart crash with Japanese date/number/currency settings

Hi,

I'm unable to reproduce the problem with the latest version of TeeChart AX and the test project you sent in. Can you confirm please if the problem as you see it shows itself in the test project?

With thanks.

Marc
