Defining multiple chart ranges via a conditioned loop

riskbubble.xlsx

Hi everyone

Help required if possible in looping through data and where Column I in the attached sheet changes, i.e. from 1 to 2, holding that range of 1s for use as a range in a chart. i.e. "B50:I53", and then doing the same for the next set of 2's etc.

There might not always be numbers 1 to 5 in column I and I need to be able to know for the range which number it is for.

I am not a VBA expert as you can tell, not that hot with arrays, either.

Any help would be appreciated.

Thanks
Sean
