Hello,
Please try setting ClusterWidth property of bar.
Following is the code which can specify what percent of available space can be used for drawing bar cluster.-
C1Chart1.ChartGroups(0).Bar.ClusterWidth = 50
However, different bars with different widths in one series of data is not a supported feature here.
When you create a bar chart, you can change the width and overlapping effects of a bar by using the ClusterWidth and ClusterOverlap properties as:-
C1Chart1.ChartGroups(0).Bar.ClusterWidth=50
C1Chart1.ChartGroups(0).Bar.ClusterOverlap = 100
But these properties are applied to the series as a whole and not to individual data pairs.
In case of any further questions, please feel free to ask.
Thanks,
Reeva
