Re: Redraw problems with HighLow with multiple charts

Hello,

Could you please arrange a simple example project we can run as-is to reproduce the problem here?

Re: Series marks with semi-transparent background

Hello, You could use events to draw the brush with transparency and draw the marks without brush later: uses Series; type TChartSeriesAccess=class(TChartSeries); procedure TForm1.FormCreate(Sender: TObject); begin Chart1.View3D:=False; Chart1.Legend.Hide; with TBarSeries(Chart1.AddSeries(TBarSeries)...

Re: Only seeing a legend

Hello, I see two options. You could modify the height of the TChart components so the heights of both ChartRects (automatically calculated) match. Alternatively, if you need to have the same height in both TChart components, or if the ChartRects automatically generated can give different height for ...

Re: Changing cell value

Hello,

Excuse the delayed reply here.
Have you seen the Virtual Mode example?
Alternatively, you can manually create a custom TStringsData and assign it to the grid's Data as in the TStringGrid example.
This and other features are explained here.

Re: Only seeing a legend

Hello,

You can hide the legend in the chart on the top and make sure the chart on the bottom has as many series as you want to be shown in the legend. Note some of these series may have no points but the series title.

Re: Chart Drops Bar Labels

Hello, 1) I remember there is a margin setting somewhere that increases the likelihood that they will be drawn (years ago support told me about it). Do you know what that is? Indeed setting thinner bars seems to help: for i:=0 to chrRothConvert.SeriesCount-1 do TBarSeries(chrRothConvert[i]).BarWidth...

Re: Area series Draw style problem (TeeChart2019.ocx)

Hello,

We are studying what alternatives we have to move a pixel to the right so the rectangles don't overlap.
We'll also consider the option of drawing polygons instead of rectangles.

Re: Remove circle around polar chart

Hello,

Series[1] returns a TChartSeries. You should cast to TPolarSeries to get access to CirclePen property and the rest of properties specific to the polar series.

Re: Area series Draw style problem (TeeChart2019.ocx)

Hello, The lines aren't being drawn. However, the rectangles are being drawn so close that it looks like there was a darker line being drawn between them: gdiplus.png If you change the Canvas to use GDI instead of GDIPlus, this effect disappears: TChart1.Aspect.GDIPlus.Active = False gdi.png Note th...

Hello,

I'll send you a test version where we're not saving the labels bounds in Android&iOS, which was the fix for #1830.
