Error using gcm?

Hi all,

I am running a code which makes a global plot using plotm before I loaded coast.mat and defines the axesm as:

axesm('MapProjection','eqdcylin','Frame','on','Grid','on',...
   'MapLatLimit',[-90 90],'MapLonLimit',lonlim, ...
   'MeridianLabel','on','ParallelLabel','on','MLabelParallel','south')

The code worked perfectly but now is not getting this message:

Error using gcm (line 25)
Not a map axes.

Error in nextmap (line 24)
    gcm; % Will error if gca is not a valid map axes

Error in nextmap (line 43)
        nextmap

Error in plotm (line 59)
nextmap(varargin)

Error in plot_data_CLCS_5x5 (line 44)
        plotm(coast.lat,coast.long);hold on; tightmap;

Anybody had the same problem and has been able to solve. Thanks in advance

It looks like another plot was initialized or clicked on after calling axesm, because this should work just fine:

figure
lonlim = [-60 120]; 
axesm('MapProjection','eqdcylin','Frame','on','Grid','on',...
   'MapLatLimit',[-90 90],'MapLonLimit',lonlim, ...
   'MeridianLabel','on','ParallelLabel','on','MLabelParallel','south')   
coast  = load('coast');
plotm(coast.lat,coast.long)

whereas this will produce the error message you're getting:

figure
lonlim = [-60 120]; 
axesm('MapProjection','eqdcylin','Frame','on','Grid','on',...
   'MapLatLimit',[-90 90],'MapLonLimit',lonlim, ...
   'MeridianLabel','on','ParallelLabel','on','MLabelParallel','south')   
coast  = load('coast');
figure % <-THIS WILL SCREW THINGS UP
plotm(coast.lat,coast.long)
