Chart: Trackball is not displayed for the first data point when CategoricalAxis GapLength is 0

Hi friends,


  my custom tooltips never work on the first bar only of the BarSeries, here is a simple example showing this behavior.  There is important data for me in that column, so let's hope it's possible to resolve this.  Many thanks!

Hi Martin,


  yes the workaround works, but it affects the appearance of the graph.  I am still hoping this bug can be resolved, but thanks in the meantime!

Hello Eric,

I guess you mean the trackball. I can confirm that this is a bug in the trackball behavior which is why I have changed its status.

To work this around, you can set the GapLength property of the CategoricalAxis to a bigger value, like 0.1

<tchart:CategoricalAxis GapLength="0.1"/>

Can you try this and let me know if it helps?
