Hi Cunbo and Guido,<br>
<br>
the simple way to do that is:<br>
<br>
<font color="#3333ff"><tt> xvalues = (/ -10, -5, 0,
5, 10/)</tt><tt><br>
</tt><tt> xlabels = (/"-10km", "-5km", "0km", "5km", "10km"/)</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> res@tmXBMode = "Explicit" ;-- set x-axis
labeling to explicit</tt><tt><br>
</tt><tt> res@tmXBValues = xvalues ;-- values for
x-axis tickmarks</tt><tt><br>
</tt><tt> res@tmXBLabels = xlabels ;-- set labels equal
to values (type string)</tt></font><br>
<br>
Bye,<br>

Hey Cunbo,
<div class="">that's a problem that I faced many times and I
haven't found a clean solution, yet. All the methods that I've
used to manually define the labels have failed somehow. The
"easy" solution that I'm using now is to define a new variable
for your axis and then use that for plotting.</div>
<div class=""><br class="">
</div>
<div class="">I believe you also have, like me, some coordinate
informations in the x and y axis although the domain is
idealized, that is defined only in terms of grid resolution,
right? So what I've done was:</div>
<div class=""><br class="">
</div>
<div class=""><font class="" face="Menlo" size="1">; 1 - defining
the half-lenght of the two axis (in your case 10 km)</font></div>
<div class="">
<div class=""><font class="" face="Menlo" size="1">half_lenght_x=10.</font></div>
</div>
<div class="">
<div class=""><font class="" face="Menlo" size="1">half_lenght_y=10.</font></div>
</div>
<div class=""><font class="" face="Menlo" size="1"><br class="">
</font></div>
<div class=""><font class="" face="Menlo" size="1">; 2 - manually
compute the two axis as km</font></div>
<div class=""><font class="" face="Menlo" size="1">; using the
longitude and latitude arrays from</font></div>
<div class=""><font class="" face="Menlo" size="1">; your input
File</font></div>
<div class=""><font class="" face="Menlo" size="1"><br class="">
</font></div>
<div class="">
<div class=""><font class="" face="Menlo" size="1"> dist_x:=(half_lenght_x/180.)*(File->lon)</font></div>
<div class=""><font class="" face="Menlo" size="1"> dist_x@units=
"km"</font></div>
<div class=""><font class="" face="Menlo" size="1"> dist_x@long_name
= "Distance"</font></div>
<div class=""><font class="" face="Menlo" size="1"> dist_x@standard_name
= "distance"</font></div>
<div class=""><font class="" face="Menlo" size="1"><br class="">
</font></div>
<div class="">
<div class=""><font class="" face="Menlo" size="1"> dist_y:=(half_lenght_y/90.)*(File->lat)</font></div>
<div class=""><font class="" face="Menlo" size="1"> dist_y@units=
"km"</font></div>
<div class=""><font class="" face="Menlo" size="1"> dist_y@long_name
= "Distance"</font></div>
<div class=""><font class="" face="Menlo" size="1"> dist_y@standard_name
= "distance"</font></div>
</div>
<div class=""><font class="" face="Menlo" size="1"><br class="">
</font></div>
<div class=""><font class="" face="Menlo" size="1">; 3 - use
these two variables, which will have the same dimension as
the coordinate variables, to plot</font></div>
<div class=""><font class="" face="Menlo" size="1"> ResC@sfXArray
:= dist_x</font></div>
<div class=""><font class="" face="Menlo" size="1"> ResC@sfYArray
:= dist_y </font></div>
</div>
<div class=""><br class="">
</div>
<div class="">Note that you will need to remove any reference to
the old coordinate variables from the variable that you're
plotting (so any attribute...).</div>
<div class=""><br class="">
</div>
<div class="">Hope that helps</div>

I am doing a contour plot with “gsn_csm_contour_map” and
I want to setup XY labels manually. Like in the attached
plot, how can I change the XBLabels “10w, 5w, 0, 5E,
10E” to “-10km, -5km, 0km, 5km, 10km “? Does anyone know
how to modify this? Thanks very much!
