Need help using contourfm in Map plotting

Normally, I can use contourf to plot a countour like this:

[C1, h1] = contourf (X, Y, Z, [7.9:0.005:8.2], 'LineStyle', 'none' );

The problem is that I'm having trouble using it on maps plotted using the Matlab Mapping toolbox. Below is my code to generate the map:

h = worldmap('Australia');
geoshow('landareas.shp', 'FaceColor', [0.6 0.6 0.6])
geoshow('worldlakes.shp', 'FaceColor', 'cyan')
geoshow('worldrivers.shp', 'Color', 'blue')

I got a huge amount of error when attempting:

[C1, h1] = contourfm (X, Y, Z, [7.9:0.005:8.2], 'LineStyle', 'none' );

How do I make a similar contour map in this case?

Many thanks.

Hi Leon,

The syntax for using the 'contourfm' function is different from that of the 'contourf' function. This is why you are getting the error.

The 'contourfm' function is actually similar to the 'contourm' function (except that the areas between contours are filled with colors).

Do take a look at the following links to understand the usage of these functions along with their similarities and differences:

contourf

contourfm

contourm

Hope this helps!
