Hi, I am using following codes to plot a 0-360 degree map, can anyone please help to show me how to remove the horizontal lines on the map created. Athough plot(X,Y,'.') does not show those lines, I wanted to plot the coastlines instead of points. Thanks in advance!
Coast=load('Coast.mat');
X=Coast.long;
Y=Coast.lat;
X(X<=0)=X(X<=0)+360;
plot(X,Y);

coastlon(abs(diff(coastlon))>180+1)=nan;

Hi! You are right, thank you!
The complete code:
load coastlines
coastlonWrapped = wrapTo360(coastlon);
index=abs(diff(coastlonWrapped))>180+1;
pos=find(index==1) %to be sure
coastlonWrapped(pos)=NaN;
plot(coastlonWrapped,coastlat)

Make sure to clear the figure before plotting because the coast.mat does not have these lines.
