Format a time as hours:minutes on a Google Charts y-axis

Question

I have a Google Chart where the y-axis is measured in minutes.

How can I format the y-axis so the labels display the time in a format like 2hrs40

Answer 1

The formatting options don't allow you to do that. You can, however, use the vAxis.ticks option to manually specify the values to use for the tick marks and the strings you want to use to represent the values. The vAxis.ticks option takes an array of objects, where each object has v (value) and f (formatted value - what gets displayed on the chart) properties. Something like this should work:

vAxis: {
    ticks: [{v: 0, f: '0:00'}, {v: 30, f: '0:30'}, {v: 60, f: '1:00'}, {v: 90, f: '1:30'}]
}

Answer 2

Google lets you do that....I'm doing this to show data like "5 mins". In your options do this:

            vAxis: {
            format: 'm \'mins\''
        },
