Ekin,
You didn't mention it, but I assume you got an error when you ran
this script?
You are using 2D arrays for your X and Y coordinate values. This
means potentially that your 2D data grid is not "nice" and linear,
and thus, NCL can't assume that a linear axis system will represent
your data correctly. In this case, then, it turns off the tickmarks.
If your data *is* on a "nice" grid, and you want to force the
tickmarks, then see example 4 at:
http://www.ncl.ucar.edu/Applications/barb.shtml
This shows how to create a "loglin" plot (log-linear) which will get
you the tickmarks you need.
In your case, the last part of your code might look like this:
plot = gsn_contour(wks,phyto(0:19,0:99),res) ; create plot
genCmapMnMxSpan (wks, plot, "Blue" , "Red") ; choose color map
getvalues plot ; get the X/Y axis min/max
for use in the loglin plot
"trXMinF" : trxmin
"trXMaxF" : trxmax
"trYMinF" : trymin
"trYMaxF" : trymax
end getvalues
loglin = create "logling" logLinPlotClass wks ; draw a loglin
plot, with expanded X/Y axis
"trXMinF" : trxmin
"trXMaxF" : trxmax
"trYMinF" : trymin
"trYMaxF" : trymax
"trYReverse" : True
end create
overlay(loglin,plot) ; overlay plot with the loglin plot
draw(loglin) ; draw the plot
frame(wks) ; advance the frame
