gwt-visualization 1.1.2 ColumnChart format y-axis

[Sal Ingrilli]

I have a ColumnChart showing duration on the y axis as seconds, so a duration of 5 minutes shows as 300, 10 shows as 600.

I want to format it as HH:mm:ss instead, so instead of 300/600, I want to show 5:00 and 10:00 and so on...

Any out-of-the-box way of doing this?

If not, any advice on how to do it?
