I've worked around the problem with something like this (using json):
var data = new google.visualization.DataTable({
cols: [{id: 'Date', label: 'DateTime', type: 'datetime'},
{id: 'data1', label: 'serie1', type: 'number'},
{id: 'data2', label: 'serie2', type: 'number'}],
rows:[ {c:[
{v: new Date(2009,1,1,)},{v: 2000},{}]},
{c:[{v: new Date(2009,1,2)},{},{v:
3000}]}
]})
I just use null values in the unused series.
hope it helps
