Auto-crop whitespace on charts

[stackpr]

Could crop white space: javascript - Crop image white space automatically using jQuery - Stack Overflow

That can also be unnecessary with properly configured chartArea.

Could preserve charteditor settings. $('#gv_chartid').data('gv_wrapper').getOptions(); The options could be written back to data tags. These changes could then be detected using .data() | jQuery API Documentation -- or we could institute a brand new event: .trigger() | jQuery API Documentation
