This is exactly what I thought at start. Any way, you can create a JSON
string in the server and convert it to a datatable very simply in your JS
file.
Let's say your server renders a JSON string like this:
{
cols: [
{id: 'task', label: 'Task', type: 'string'},
{id: 'hours', label: 'Hours per Day', type: 'number'},
{id: 'timestamp', label: 'My Date', type: 'date' }
], rows: [
{c:[{v: 'Work'}, {v: 11}, { v: new Date(2011,1,1) }]},
{c:[{v: 'Eat'}, {v: 2}, { v: new Date(2011,1,1) }]},
{c:[{v: 'Commute'}, {v: 2}, { v: new Date(2011,1,1) }]},
{c:[{v: 'Watch TV'}, {v:2}, { v: new Date(2011,1,1) }]},
{c:[{v: 'Sleep'}, {v:7, f:'7.000'}, { v: new Date(2011,1,1) }]}
]
}
You can load the datatable in the following way:
var data = new
google.visualization.DataTable(eval('('+serverJSONString+')'), 0.6)
