how to change my lat and lon value to more precise notation ?

1 次查看(过去 30 天)
Hi,
I have these two images ( please see the attached). the first image is taken from a paper and I made the second image. i want to make my 2nd image lat and lon notation look exactly the same as my first image. like 70 degree W inastead of just 70. Is there any way to change the format ? Thanks and i would accept any answers.

Since R2015a or so:
ax = gca;
ax.XRuler.TickLabelFormat = '%g \\circ W';
This will not use the true degree symbol: for that instead use
ax = gca;
ax.XRuler.TickLabelFormat = sprintf('%%g%s W', char(176));

thanks very much. looks like it worked but it added negative signs in front the numbers. How do i get rid of the negative signs ( please see the attached ) ? Thanks again

Unfortunately you cannot control the negative sign by using the TickLabelFormat and will instead need to set the XTickLabel property to contain a cell array of the exact strings you want to use.
If you expect the user to zoom or pan then you will need to add support for a resize callback to change the XTickLabel property to suit the new axes limits.
If you expect the user to be able to use the data cursor then you will need to use datacursormode() and an UpdateFcn to construct the appropriate strings instead of the decimal degrees.
