I have a graph of Min and Max hours on the x, y axis.

I would like the ability to create a bubble chart in Zoho Reports.  That is, size of the bubble at certain point (say 5, 10) would be relative to the number of records with those matching values.  So if 10 records have (5 ,10), and 5 records have (4, 16) , the bubble at point (5, 10) would be twice as big as the bubble at (4, 16)

Currently, the scatter chart, shows all the data points, but I'd like the size of the bubble to be related to number of matching records.

Thanks.

Cheers,
Tyler
