Perspective xychart issue

I’m trying to get an XYChat compnent to display date on the xaxis and time on the yaxis. I’ve managed to get the xaxis to display the date(I’m doing it in column style) but for the yaxis I can’t get it to display time. I can have it display an integer value, but ideally I would want to display something with the hh:mm:ss format.
This is to display the amount of time a line runs each day, so I dont want to display a time of day, but a time amount.

Any help will be appreciated!
