The charts are rather thoroughly documented (although errors do occasionally crop up). Since you bring up Pie Charts, I'll use them as an example:
Create a DataTable as documented here: http://code.google.com/apis/chart/interactive/docs/reference.html#DataTable Pie Charts require data to be presented as two columns, as documented here: http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Data_Format Pie Chart configuration options are documented here: http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Configuration_Options Pie Charts are drawn with the PieChart#draw method, as documented here: http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Methods Options are passed to the draw function as an object, documented here: http://code.google.com/apis/chart/interactive/docs/reference.html#visdraw If all of this isn't clear, there is the visualization playground here: http://code.google.com/apis/ajax/playground/?type=visualization#pie_chart which allows you to experiment with the API and figure out how all the API's components work together. If that still doesn't help you, then perhaps we can offer some assistance. There are some things that the API cannot do, and AKAIK, making the background transparent might be one of them. Some limitations can be hacked around, others cannot (at least, not easily). -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
