I'd like to draw a compound Google Chart with a column chart and line chart.
I've read the docs on compound charts, but the examples are all for bar charts using GET options in URLs.
My chart is a column chart, built using the full Google Visualization API - not a bar chart using GET options.
Does anyone know if it's possible to add compound charts to a column chart?
If so, please could you give an example of doing it with the Visualization API?
Thanks.
