Hi,
The datasource (as you pointed) should be in your case a JSON format
datatable object, as in the following format:
var data = new google.visualization.DataTable(
{
cols: [{id: 'task', label: 'Task', type: 'string'},
{id: 'hours', label: 'Hours per Day', type: 'number'}],
rows: [{c:[{v: 'Work'}, {v: 11}]},
{c:[{v: 'Eat'}, {v: 2}]},
{c:[{v: 'Commute'}, {v: 2}]},
{c:[{v: 'Watch TV'}, {v:2}]},
{c:[{v: 'Sleep'}, {v:7, f:'7.000'}]}
]
},
0.6
)
so unless your data looks like this, your chart will not be shown.
