Been desperately trying to figure out how to use the labelValueFormatter for the SimpleYAxisDrawer, but I just can't seem to figure out how to use it. I have a value that is in seconds and I need to convert it to a string that's something like "1h 30m 23s", but there are no examples, samples, or documentation that I can find on how to use the label formatter. Could you please either post up an example here, or add it to the BarChart sample. I really need this feature. Thank you
