Re: FMX Chart Editor issues

Hello, When adding a Shape Series, you cannot select a Style, or Text alignment, or the units. I've seen that so I've added to the public tracker at #2486 . And I've corrected it. In OSX some of the labels are broken, wrapped, or cut off because of formatting in the individual FMXTee.Editor.xyz file...

Re: Sorting and Grouping data in Lazarus

Hello,

I'm afraid the only way to do this would be using a different structure as explained here.

Re: Hiding Points in a Series

Hello Save, Yes, you can hide specific points by setting them as "null points". Ie: Private Sub Form_Load() With TChart1 .Aspect.View3D = False .Legend.Visible = False .Panel.Gradient.Visible = False .Panel.Color = vbWhite .Walls.Back.Gradient.Visible = False .Walls.Back.Color = vbWhite .Axis.Left.G...

Re: Sorting and Grouping data in Lazarus

Hello,

I'm not sure to understand the situation. You seem to be adding two sub-columns under "TITLE", but then you want to concatenate them?
Could you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Re: TeeGrid - Delphi 11

Hello, I have noted your reply but how to resolve it ? As I mentioned above, you could add the "Sources" and "Sources\FMX" folders to the "Library path" for "Linux 64-bit" platform. Have you tried it? I have tried to download the teegrid binary 1.11 from the official web site but the downloaded bina...

Re: EMF Optimisation for charts

Hello, It doesn't seem that TDownSampling function works if series have more than 15000 of points. As shown in the example above, it's an improvement against using the TFastLineSeries per default. But you won't probably notice an improvement if you are using daMinMax . Adn how can i use function wit...

Re: EMF Optimisation for charts

Hello, I've done a simple application to test how the export performs with the "default" TFastLineSeries , setting DrawAllPointsStyle.daMinMax , using a TDownSampleFunction and using a TDownSampleFunction with DrawAllPointsStyle.daMinMax .

Re: EMF Optimisation for charts

Hello, The time TeeChart spends to draw points (lines in the case of TFastLineSeries / TLineSeries ) depends on factors like the number of shapes/lines to draw, the complexity of the brushes to be used (gradients, dash lines,...) and the specifications of the target machine. We use to recommend tryi...
