I have a table of utility type and their cost.
A sample is as follows
Utility Date Cost
gas Jan. 2013 100US$
gas Feb. 2013 95$
electricity Jan 2013 200US$
electricty Feb 2013 195 $
Telephone Jan 2013 500$
Telephone Feb 2013 300$
gas March 2013 200$
and goes on
I want to draw graph for each utility separetly at the same time.
How can I do that?
I know I can filter 'gas' and then draw its graph. But it will change if I change filter to show only
electricity or telephone.
