Floating point precision in y axis?

[Wells Oliver]

Is it possible to specify the precision of floating point values in graph axes? I'd like the values shown to three points but I can't seem to force this.

Thanks.

Set the vAxis or hAxis's (depending on which you want to format) format property to something like "#.###", ie:

vAxis: {
    format: '#.###' // show axis values to 3 decimal places

Thanks. It's odd, but '#.###' does not work, yet '0.000' does work.

Also: is there a way to set the floating point precision for the values shown in the tooltip?

Sorry about that - the one I posted will restrict to 3 significant figures, but it won't force them when the value wouldn't use them normally.

To format the tooltips, use a NumberFormatter on the DataTable column.  You can use the same format pattern.
