I don't know how to limit the study area only for the golf of guinea. lneed help for the modification of the coordinates

lonlim=[-180:180];
latlim= [50:90];
style= 'boxfill/alg'

I would like to represent the distribution of ph in the Gulf of Guinea. at line 17 of my code there is a bug. please I would like you to help me to correct this and also to limit my study area at the level of the golf of guinea thank you in advance

%read data corresponding to the parameters
[A,B]=wmsread(variable,'Time',date,'Stylename',style,'latlim',latlim,'lonlim',lonlim); %my problem starts at this line

%plot data

WMSinfo.Layer(ph_idx).Abstract

ans = 'PH'

%Define the parameters of the plot

%plot data

ax = axesm('eqaazim','MapLatLimit',latlim,'FlatLimit',[],'MapLonLimit',lonlim);

Warning: Ignoring the value provided for 'MapLonLimit'. If you are trying to use the 'MapLonLimit' property to initialize the equatorial aspect of an azimuthal projection, you should precede it with 'FLatLimit',[] in your call to AXESM.

geoshow(ax,A,R)

land = shaperead ('landareas','UseGeoCoords',true); %plot coastlines
geoshow(land,'FaceColor',landcolor) %plot land
