Re: VirtualModeData column sorting, vertical scroll bar and Page Up and Down key

Hello, Re. "The Key Page Up moves the cursor row up 10 rows. Where is the number of rows to move set?" That is currently fixed at 10. We'll add a property to control that. ( http://bugs.teechart.net/show_bug.cgi?id=2352 ) Re. The Key Page Down moves the cursor row to row number 11. This is not norma...

Re: Very long canvas - print fail

Hi, Found it. There is a maximum pixel limitation setting in TeeChart, used to control out-of-bound axis calculations, that we'll need to review. It's currently set to $7FFF (decimal 32767). Whilst we check what to do, if you have the sourcecode version you can modify it as an interim workaround: ie...

Re: Very long canvas - print fail

Hello, The metafiles don't seem to have saved correctly in the zip you posted, but we'll take another look at this to see if we can shed any light. With the current version of TeeChart the plot cuts the last data points in the metafile at exactly 32,767 pixels, the known limit for a metafile. The ca...

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.

Re: Very long canvas - print fail

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;

Hello,

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