Re: Editor in code?

Hello,

There is no editor for the HTML5/Javascript version. It is possible to code editor options for runtime as in these examples:

Re: [2020.30] .Net Framework 3.5 Win10

Hello,

It shouldn't be necessary to uninstall Framework 4.0 to install v3.5, they can run side-by-side.

Re: Assigning Ternary Vertex Titles

Hello,

Thankyou for the bug reposrt. There seems to be a problem with the serialisation of the values.

You can modify them by code in this way:

Code: Select all

Series2.VertexTitles[0].Text := 'My A Title';
It has been logged here to be fixed.

Hello,

If you export to metafile in both cases there may be a clue to the different behaviour.

Re: Winapi DrawText on chart no longer use canvas settings

Hello,

When using GDI+, TeeChart uses the GDI+ DrawString method internally.

Re: getmarktext not triggering for every value in series

Hello,

Default behaviour may have changed between versions. TeeChart now checks for Marks that will fit and reduces the Draws accordingly.

You can disable that behaviour via:

Code: Select all

Series1.CalcVisiblePoints := False;

Re: Transparent bands

Hello Anders, The code is very similar in Delphi. I'm not sure exactly which part you need, but bear in mind that TeeChart VCL/FMX has a Colorband tool that may be used to plot the rectangles. If you wish to do so manually, then use the OnBeforDrawSeries event in a similar way. eg. procedure TForm14...

Re: How to have independent Axis left and right

Hello,

One way to achieve that would be to set the Right Axis scale in the OnZoom event.

ie.

Code: Select all

procedure TForm14.Chart1Zoom(Sender: TObject);
begin
  Chart1.Axes.Right.SetMinMax(0,volumSeries.MaxYValue * 4);
end;

Re: ValueIndex in GetAxisLabel event

Hello,

Not all LabelStyles pas ValueIndex. LabeStyle "talPointValue" passes the ValueIndex.

Hello Microsolutions,

We'll look to put an extra check in to avoid that behaviour.

Re: ISO CHARTS

Hello,

Where you refer to ISO AXES I assume you've seen this demo:

https://github.com/Steema/TeeChart-VCL- ... metric.pas

It is designed to set the increments equally across x and y axes. Is that now what you have in mind?

With thanks.
