Hey,
I'm a newbie to google charts and have been playing with the diff charts -
the diff scatter to be exact.
I can set the tooltip of a point on a scatter chart by adding a column with
role of tooltip
var newData = google.visualization.arrayToDataTable([
['Data1', 'Data2', { role: 'tooltip' }],
[356070, 8034, 'tooltip1'],
[177101, 91863, 'tooltip2'],
[84194, 1304, 'tooltip3']]);
but if I then try to create an 'old' data set
var oldData = google.visualization.arrayToDataTable([
['Data1', 'Data2', { role: 'tooltip' }],
[356070, 8034, 'tooltip4'],
[177101, 91863, 'tooltip5'],
[84194, 1304, 'tooltip6']]);
and create a diff dataset
var diffData = chartDiff.computeDiff(oldData, newData);
and plot this in a scatter chart the tooltip information is not used.
Any ideas on how to get tooltips on the diff scatter plot?
Thanks!!
Colin
