Changing origin for sidestacked bars

[Andrew S]

I am using TeeChart Pro 7.06. I can't figure out how to change the origin of a chart containing horizontal stacked bars.

Using non-stacked bars it's simply a matter of setting Series.UseYOrigin := true and Series.YOrigin := -100 (for example). But when I introduce a stack, the origin seems to have little to no effect. Any suggestions as to why? I would like to have two stacked horizontal bar series, and have the lower bar's origin somewhere around -95.

Thanks,

Hello Andrew S,

I tried to reproduce your problem. For me this works fine:

Code: Select all

Series2.UseYOrigin := true;
Series2.YOrigin := -100    ;
Series1.UseYOrigin := true  ;
Series1.YOrigin := -100    ;
Series1.FillSampleValues(2);
Series2.FillSampleValues(2);

Maybe I miss understood your question. Let use know if there is any further information helping use to help you.

A slight modification to your code shows exactly what I'm asking...

Code: Select all

  Series2.UseYOrigin := true;
  Series2.YOrigin := -100;
  Series2.StackGroup := 1;
  Series2.MultiBar := mbStacked;
  Series1.UseYOrigin := true;
  Series1.YOrigin := -100;
  Series1.Stackgroup := 1;
  Series1.MultiBar := mbStacked;
  Series1.FillSampleValues(2);
  Series2.FillSampleValues(2);

Notice that, even though the bottomaxis' minimum has been modified, the stack still originates at 0?

Hi Alex,

yes, you're correct, it still not prepared to be used with Stack and negative YOrigin, I've adde this on our defect/wish list to be considered for the next maintenance releases.

I notice in the release notes for 7.07 that it mentions improvements to the way stacked bars are drawn. Does this include my issue, or is that going to be a future release?
