Hi Adam,
After using these explicit values, no tickmark is getting printed on the plot.
I'm attaching my current resource list, by using this I'm getting tickmarks on plot, but all are major tickmarks. No minor tickmark is getting ploted.

Hi Amit,
Can you send your complete resource list that you are using?
Slight correction to what I sent earlier:
res at tmXBMode = "Explicit"
res at tmXBValues = (/1,10,20,30,40,50,60,70,80,90,100,110/)
res at tmXBLabels = res at tmXBValues
res at tmXBLabelFontHeightF = 0.01
res at tmXBMinorValues = ispan(1,114,1)
Your data runs through 114 on the x-axis. If you want to set the tickmarks like this:
res at tmXBValues = (/1,10,20,30,40,50,60,70,80,90,100,110,120/)
and draw the 120 label, you will also need to set res at trXMaxF = 120

Hi Adam,
Still the tickmarks are of same height (Plot attached).
Also when in explicit mode I'm giving res at tmXBValues = (/1,10,20,30,40,50,60,70,80,90,100,110,120/), then also it is giving me error that x axis data out of range, going to default.
However, when I'm plotting for only 30 days, I'm getting the desired plot (attached), that too without using any tickmark resources i.e. res at tm as you can see in the script attached in 1st message.
Regards
Amit

Hi Amit,
Try this:
res at tmXBMode = "Explicit"
res at tmXBValues = var&time
res at tmXBLabels = ispan(0,115,5)
res at tmXBLabelFontHeightF = 0.01
res at tmXBMinorValues = ispan(0,115,1)

Dear All,
When I'm following as mentioned in example 2, then no labels are getting printed on x axis.

You might look at "tmXBMinorValues " at
http://ncl.ucar.edu/Document/Graphics/Resources/tm.shtml
and example #2 at
http://ncl.ucar.edu/Applications/tickmarks.shtml
for dealing with minor tickmarks when using tmXBMode = "Explicit"

Hi All,
I've made following changes as suggested by Adam in the script,
res at tmXBMode = "Explicit"
res at tmXBValues = var&time
res at tmXBLabels = ispan(0,115,1)
res at tmXBLabelFontHeightF = 0.01
res at tmXBLabelStride = 10
Now as it can be seen from the image that all the labels are major labels, is there a way to define all other tickmarks except for which label is mentioned as minor tickmarks.
Regards
Amit

Hi Amit,
You can override the behavior of the bottom x-axis tick mark labels by setting:
res at tmXBMode = "Explicit"
res at tmXBValues = OLR_DAY&time
res at tmXBLabels = ispan(1,115,1)
See tickmarks example #2 here (bottom panel coding):
http://www.ncl.ucar.edu/Applications/tickmarks.shtml#ex2
Tick marks - University Corporation for Atmospheric Research<http://www.ncl.ucar.edu/Applications/tickmarks.shtml#ex2>
www.ncl.ucar.edu<http://www.ncl.ucar.edu>
NCL graphics examples page. Describes various tick mark resources and ways to manage the tick marks.
If you have further questions please post them to ncl-talk.

Dear Rick,
Actually these 115 time stamps are for each day. I have concatenated to these individual days into one using cdo. I want to plot time at x axis which will vary from 1 to 115 indicating each day, so that the plot can be ploted as latitude vs time and variation of olr can be seen over latitude and time . It is on the same lines as the example for sst anamoly in latitude vs time section in ncl examples.

Hi Amit,
Offhand, given the time variable's coordinate range:
Variable: time
Type: double
Total Size: 115 values
920 bytes
Number of Dimensions: 1
Dimensions and sizes: [ 115 <time | unlimited> ]
Chunking Info: [ 524288 <time> ]
Coordinates:
time: [9159840..9334080]
I'd the plot looks about what I'd expect. In what way do you think the time values are incorrect?

Dear All,
I'm trying to plot Latitude vs Time Plot. It is working fine when I've 30 time instances, but for greater then that (i.e. 115 time steps) the plot is sowing different values in x-axis (time).
I'm not able to workout why this is happening? I'm attaching the output and my ncl script.
