Progressive Chart on C11 Reporting

[Sans]

Hi

I have a C11 report containing a progressive chart (not a RAVE but a standard progressive chart). In this chart values are progressive starting from 0 but increasing from the value of the previous element.

Rather then this, I'd like to have a chart having positive values always starting from 0 not from the end of the previous value.

Pls see attached image

Any idea ??

Thanks
