Hello, I am using the mapping toolbox to plot some marine data on a world map. Everything looks fine, but when I save the file as an editable vector image (e.g. '-depsc' ), the resulting image contains strange marks and lines (see here: http://imageshack.us/photo/my-images/820/screencapturemr.png/).

It works fine for bitmap formats (e.g. 'dpng'), but I want the image to be in vector format such that I can edit it in Illustrator.

I don't have any idea what I can do to fix this problem.

Here are the commands that I used to create the world map:

figure(1); ax = worldmap('World'); setm(ax, 'Origin', [0 -140 0]);

setm(ax, 'meridianlabel','off'); setm(ax, 'parallellabel','off');

land = shaperead('landareas', 'UseGeoCoords', true); load coast; lakes = shaperead('worldlakes', 'UseGeoCoords', true);

geoshow(ax, land, 'FaceColor', [0.6 0.6 0.6],'EdgeColor','none');

geoshow(lakes, 'FaceColor', [0.6 0.6 0.6],'EdgeColor',[0.6 0.6 0.6],... 'LineWidth',3.0);

After I plotted the data and added a colorbar etc., I save the figure with the following command lines:

figure(1); set(gcf, 'PaperPositionMode', 'auto'); print -depsc2 worldmap.eps

Is this a common problem with the mapping toolbox or do I do something wrong? Is there a way to fix it? Thank you in advance for your help or any suggestions.
