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: Chart Drops Bar Labels

Hello,

It would be helpful if you could post the code to generate the chart you are showing us so we can reproduce the situation as-is.

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.

Re: Mix builds?

Hello, You can switch from a TeeChart version to another just by modifying the library path. So, if they are different projects, you should be able to compile your 95% with TeeChart Lite and the other projects with TeeChart Pro. If you have TeeChart Pro with sources you could download an old version...

Re: Why is Contour Series much slower when using filled mode

Hello,

The method that needs more time is the TIsoSurface.DrawCell. We could add an event in it but it could have a negative impact on the performance.

Re: OnGetMarkText is not fired in TContourSeries

Hello, I'm afraid that fix arrived just a few hours after closing v2019.28 so it will be included in the next maintenance release. I can't say when it will be released but you get an idea knowing the latest releases dates: March 2017, June 2017, December 2017, March 2018, August 2018, December 2018,...

Re: Why is Contour Series much slower when using filled mode

Hello, I'm afraid the filling of the contour series isn't so simple as one could think at a first glance. We are internally using a TIsoSurface to draw the cells, which makes the process slower.
