Re: Y-axis label and values

Kalim,

If your tickmark labels are not showing up in "explicit" mode, then
usually the problem is that the tickmark values you're using are not
within the range of your axis values.

Since I can't run your script, I'm not sure what your Y axis values
are. You need to look at the arrays zAvgTime&time and major_ticks
and make sure they are in the same data space.

major_ticks should be set to values that are within the range of your
time values.
