Subgroup with clustered graph

[Claudia]

I would like to create a subgroup with a clustered graph. The first group will be the columns headers and the second one, the description in my first column.

The axis will be represented this way :

X - 2 groups

Y - The corresponding value between the 2 groups

I am using Telerik 2016.

English is not my first language, but I think that the image in attached files sums what I am trying to do.

Thanks in advance!
