TSeriesBandTool issues VCL 2017

[Thomas]

Hi, i am currently migrating projects from Delphi 2009 / TeeChart VCL 8 to Delphi 10.1 Berlin / TeeChart VCL 2017 (OS Seven 64bit).

I have noticed "changes" on series band tool, i use them with multiple TLineSeries and a common one as baseline:

- Some of them (seems the first 2) are correctly drawn but the others are not painted until i do, for instance, a zoom and unzoom (already tried to add a chart.Repaint after series filling with no success).
- the second issue, by unchecking on the legend serie checkbox, the serie band remain visible (on TeeChart VCL 8 it is synchronized, both serie and its band are visible or not driven by legend click)

I have attached a project showing these issues.

Could you please help.
Regards
Thomas

Hello Thomas,

- Some of them (seems the first 2) are correctly drawn but the others are not painted until i do, for instance, a zoom and unzoom (already tried to add a chart.Repaint after series filling with no success).

I see calling Draw twice corrects the problem. I've added it to the public tracker here:
http://bugs.teechart.net/show_bug.cgi?id=1838

- the second issue, by unchecking on the legend serie checkbox, the serie band remain visible (on TeeChart VCL 8 it is synchronized, both serie and its band are visible or not driven by legend click)

With v8.08 I get a band still drawn, even if all the series are disabled:

I could reproduce and identify the problem here:

I've also fixed it for the next maintenance release.

Hello Yeray,

calling Draw twice works perfect, thanks.

Do you have a planned date for the release of the next version?

Kind regards
Thomas

Hello Thomas,

We don't work with closed deadlines, but we try to publish new TeeChart VCL/FMX releases quarterly; and we just published v2017.21 so the next one should be around July
