How to set tooltips to display percentages to match axis?

[B7]

I used the tooltips to display percentages using the following code:

var formatter = new google.visualization.NumberFormat({
fractionDigits: 2,
suffix: '%'
});
formatter.format(data, 1); // Apply formatter to first column.

Is there a way for NumberFormat to multiply each element by 100?
Otherwise the tooltip appears as .50%.

I am using vAxis.format = "format:'#%' " which does multiply by 100.
So .5 is displayed as 50% on the vertical axis.

According to the documentation(icu-project.org/apiref), this can be
overwritten by enclosing the % in single quotes, but this did not
work.

The net result is that the tooltips do not match the axis. What is the
best way to do this?

Thanks.

Use the NumberFormat's 'pattern' option:

var formatter = new google.visualization.NumberFormat({

    pattern: '#%',

    fractionDigits: 2

});

That worked. Thank you!
