Dear All,
I created a map with eqdcylin projection by the following way:
axesm('eqdcylin','maplatlimit',[26.5861 71.8699],'maplonlimit',[-34.748 60.8422]);
pcolorm(lat,lon,IU2);
colormap(jet)
I attached the result. I would like display the longitude and latitude values in the map. I have ever tried to use
load coast
plotm(lat,long)
based on http://www.esrl.noaa.gov/psd/data/narr/format.html but it does not work. Can someone suggest me a solution?

I'm not exactly sure what you mean by "display the longitude and latitude values in the map". If your looking for grid lines with labels, then try this:
gridm on
mlabel on
plabel on

noticed you had
plotm(lat,long)
did you mean "lon" instead of "long"
Also, look into the m_plot package, it's an old open-source build, allows you to choose the projection first (m_proj), then plot (m_plot)...
