Hi Alex,
The angularjs component you are using should be fixed to load Google Charts
properly. That may take time for someone (any idea who?) to implement.
In the meantime, you should be able to add a timeout loop to your code
before you start making calls to the Google Charts functions. Something
like this:
function maybeDrawChart() {
if (!window.google || !google.visualization ||
!google.visualization.DataTable) {
setTimeout(maybeDrawChart, 2000);
return;
}
// DataTable has been defined, so now we can proceed to draw the chart.
....
}
setTimeout(maybeDrawChart, 1000);
