@arj,
Thank you for your feedback on the column gaps in the chart. The varying space between the columns occur to make them look crisp & avoid a blurry appearance, especially with a larger number of datapoints. We’ll revisit this behavior to improve it in future versions. In the meantime, you can try setting dataPointWidth to a smaller value if that helps in your case.
