sort the serial chart by statistics

[HalaAbdelmaksoud]

Hi all,

When I have a serial chart by category (the categories on the category axis) and each category has a sub-category(A&B), the sorting by statistics gives options to sort by each sub-category(A&B) individually which is sometimes doesn't deliver the purpose of my chart like the image below. 

My idea is to have the option to sort by just the total count of the main category itself, not for each sub-category(A&B). I hope it will be added to the dashboards soon.
