Hello everyone.

Is my first time trying to use the Mapping Toolbox. I need to do a polar equal-area azimuthal projection. I would like to make something like this (I made this one using polarplot function):

But using the mapping toolbox, this is what I get.

So, I have to change the latitude/longitude labels of latter projection (from Mapping Toolbox) to something similar to the first one (when I did make use of polarplot function). Is it possible to do this with mapping toolbox?. How could I make it?.

Thank you.

PD: This is the code that I'm using with the Mapping Toolbox.

axesm('lambert',...
    'MapProjection','eqaazim',...
    'Frame','on',...
    'Grid','on',...
    'MapLatLimit',[0,90])
axis off; framem on; gridm on; mlabel on; plabel on
setm(gca,'FLineWidth',1,...
    'Origin',[-90,0],...
    'MLabelParallel',0,...
    'MLineLocation',10,...
    'PLineLocation',10,...
    'MLineLimit',[-80,80],...
    'MLineException',[-90,0,90,180],...
    'PlabelLocation',20,...
    'labelrotation','on')
northarrow('latitude', 10, 'longitude', 0);

You may check the Map Axes Properties to control axes appearance and label properties. You can use mlabelzero22pi to change the range of labels to 0-360 degrees. Following code shows addition of two properties to your code and mlabelzero22pi which can fetch a similar look to that of your polar plot:

setm(gca,'FLineWidth',1,...
    'Origin',[-90,0],...
    'MLabelParallel',0,...
    'MLineLocation',10,...
    'PLineLocation',10,...
    'MLineLimit',[-80,80],...
    'MLineException',[-90,0,90,180],...
    'PlabelLocation',20,...
    'labelrotation','on',...
    'LabelFormat','none',...
    'PLabelMeridian','prime')
mlabelzero22pi
