How can I make a chart using field type "Group of Checkboxes"? I want to create something like a histogram bar chart, where each for each value in the checkbox group the chart lists the # of records with that value checked. It appears that the Group of Checkboxes field type is unavailable for use in Charts. Is there a workaround?
I afraid not. Chart only counts record once.
However you can create HTML template which will use any chart service available on the web the way you want. Particularly try charts provided by Google.
Ok, very well; I'll fiddle around with Google charts. Thanks.
