Re: Y-axis label and values

Dear Mary, thanks for your response. Actually, I want to plot as example (hov_7.ncl:) but after some mudification I got the figure without label(i.e.month names) on y-axis ,so my plot is attached herewith.
thanks

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.

Dear NCL Users,
I’m trying to plot time vs lon figure but after plotting there is no Y-axis labels and values appear and also no error. Please could you help me in this regard? My script is attached given below:
Thanks in advance
