Re: multiple charts

Put each series of data into its own column.  It is fundamentally no different than using a single series of data.

For mulitple columns i get data like this but it doesnt draw both the lines ...

{ "cols": [ {"label":"Dat","type":"date","role":"annotation"}, {"label":"RETURNING VISITS","type":"number"} ], "rows": [{"c":[{"v":"Date(2012,11,28)"}, {"v": 0}]},{"c":[{"v":"Date(2012,11,29)"}, {"v": 0}]},], "cols": [ {"label":"Dat","type":"date","role":"annotation"}, {"label":"NEW VISITS","type":"number"} ], "rows": [{"c":[{"v":"Date(2012,11,28)"}, {"v": 5}]},{"c":[{"v":"Date(2012,11,29)"}, {"v": 5}]},]}

Your JSON isn't formatted correctly.  First of all, the annotation role isn't valid for the domain column ("Dat" in your example).  Also, you need to include all 3 column definitions together, and populate all rows with 3 columns of data, like this:

{ "cols": [ {"label":"Dat","type":"date"}, {"label":"RETURNING VISITS","type":"number"}, {"label":"NEW VISITS","type":"number"} ], "rows": [{"c":[{"v":"Date(2012,11,28)"}, {"v": 0}, {"v": 5}]},{"c":[{"v":"Date(2012,11,29)"}, {"v": 0}, {"v": 5}]}] }
