I have troubles with the contourfm function (mapping toolbox) when plotting some data. The issue is that contourfm would fill the entire plot with just one color, which is clearly wrong. pcolorm and contourm both display data correctly. Is this a bug in the contourfm function?

I am using: MATLAB Version: 8.1.0.604 (R2013a) and Mapping Toolbox Version 3.7 (R2013a)

The data can be found here (mat file): http://www.atmos.washington.edu/~andreasm/data.mat

 clear all; close all;
load data;
% This works:
figure;
worldmap('world');
pcolorm(lat,lon,data');
colormap(jet);
caxis([0 1]);
% But this doesn't:
figure;
worldmap('world');
contourfm(lat,lon,data','Linestyle','none');
colormap(jet);
caxis([0 1]);

This is how it should look like (using pcolorm): http://www.atmos.washington.edu/~andreasm/works.jpg

This is how it looks with contourfm: http://www.atmos.washington.edu/~andreasm/doesnotwork.jpg

In case this question is still open: another thread is now (Dec 2013) active to reply to the same issue, see Getting errors using contourfm after upgrading to 2013a
