Hello srikanthBugga,

We are still following this forum thread. Have you been able to take a look at the attached sample?

Please feel free to let us know if you have any other questions with this matter.

Hello,

Thank you for your post. I have been looking into it and I created a sample project for you, using custom series. In the series the data points are grouped based on the date time and stacked columns are rendered based on how many data points have the same date time value.

Hope this helps you.

I have checked this link but in that  only two column series are defined. I want to define the column series for each downtime reason based on date and getting the Number of Downtime reasons  from datatable at run time. Number of downtime reasons may vary. I hope that you understand the issue. If not , Please let me know.
