I'm trying to create a bar chart for water usage grouped by month, by year, such that all January's for the years selected are grouped, then all Febrary's, then all March's, etc. I've installed the Custom Charts, as well as created group charts where the date field is defined in group 1 by month and in group 2 by year, put summary totals for the usage field in the group footers, but nothing creates my needed presentation. Any ideas?
