Hello Yeray, Thanks for the Tip, but all these lines add too much "Noise" to the graphics. I am now creating an extra TPointSeries that contains the violating Points as Yellow semitransparent circles. So the graphics only gets more populated with "stuff" in case there are min/max violations. Capture...

We often show process values/parameters using multiple Line series: Capture.PNG Now we want to highlight values per Line series that are outside certain user given min/max limits. Is there a TChart Tool or a certain Series for that, or do we need to develop our own tool for that? Like drawing someth...

Ok, I just had to populate the Title properties of the Line Series, all perfect now, thanks!

Thanks a lot, we are practically there: NewCapture.PNG I am setting the Position in the Create of the form but it looks like I need to update the position of the extra legend before the painting. One other quick question, how can I change/influence the texts that are shown in the Extra legend, I'd l...

To phrase this question differently, how can I explicitly decide in which of both (or more) Legends any Series is shown?
Because Series.ShowInLegend is global for all Legends.

Hello Yeray,

Thanks for the quick response, that indeed seems to be a way to proceed.
But how can I make sure to just just show the 3 Line Series in THAT extra legend?

Best regards,

Thomas

Hello, We produce graphics like in the attached plot with TChart, where we use a ColorGrid plus 3 Line Series. Usually we display the Colors of the Color Grid in the Legend. Now we want in addition to show a legend for the 3 Line Series. But when we include the Line Series in the Legend the Color Gr...

I just found out that I can fix this problem by calling "CreateDefaultPalette()" After populating TSurfaceSeries or TColorGridSeries.
That call was not required in previous versions of TChart VCL.

Hello TChart Team, There is a problem/bug since the latest version of TChart VCL, with the Display of 3DGridSeries when "UsePalette" is set/used. Everything is displayed in just ONE color and the Legend just shows Zeros. PaletteProblemCapture1.PNG When I then go into the Chart dialog and Set "UsePal...

Hello, I just installed RELEASE 2023.39.231109 and I noticed that suddenly certain calls are missing: VCLTee.TeCanvas.TChangeVisual VCLTee.TeCanvas.TEditVisual VCLTee.TeCanvas.TVisualEditor VCLTee.TeCanvas.TVisualEditorClass VCLTee.TeCanvas.ClipCanvas VCLTee.TeCanvas.UnClipCanvas Are these maybe ren...

Hello Yeray, it would be great though if registered users had access to a TChart source version for Delphi Betas, like Yukon. We heavily rely on TChart for graphics on mobile platforms and it would be welcome if we could test our products early (before release) too, before everything is set into sto...

Hello,

I meant of course, how to implement pinch zoom and panning for 2Dim charts, like Line charts?
