I used the JSON response because the JSON generated by the python
library is reported as invalid when imported through ajax.
I cannot get the annotated time line data to load correctly. Maybe it
has something to do with {v:new Date(2011,8,29,12,53,42)} in the
table.
If I get them to load correctly, how would I join the rows arrays?
This is what my php generates:
$.get("data/testbiertje2/testbiertje2-2011-09-29.json", function(json)
{
eval("var jsonstring =
" + json)
beerData = new
google.visualization.DataTable(jsonstring);
});
