I have a chart showing number of calls per employee as a column graph and
duration of calls as a line graph together. The scale is automatic. The scale
for the number of calls works great. The scale for the duration works, but it
doesn't use nice numbers. For example, if my employee with the longest
duration is currently at 01:55:43 (hh:mm:ss), the top of the scale shows
02:09:36. I want to keep it on automatic, but I want it to use nicer numbers,
like 02:00:00 or 02:15:00 instead of 02:09:36. Is there any easy way to do
this? If not, is there any way to do this?

Thanks,
