Hi Richard,
Thanks for using Syncfusion products.
If your intention is to reduce the gap between column and chart area which was mentioned by you in your last updated screenshot, we suggest you to set range value to X-Axis for reduce the space. Please refer the below code snippet to achieve this,
[C#]
ChartModel.PrimaryXAxis.Range.Min = ChartModel.PrimaryXAxis.Range.Min + ChartModel.PrimaryXAxis.Range.Interval / 2;
ChartModel.PrimaryXAxis.Range.Max = ChartModel.PrimaryXAxis.Range.Max - ChartModel.PrimaryXAxis.Range.Interval / 2;
Please let us know if you have any concern.
Note:Please refer the attached screenshot for chart control.
Regards,
Vijayabharathi
