Compatibility Considerations

In earlier versions of MATLAB, you could do the following:

load geoid

worldmap world

contour3m(geoid, geoidrefvec, 10)

h = handlem('contour3d');

(The output h is an array of patch object handles.)

In R2010b, to achieve a comparable result, you can use:

h = handlem('contour');

(The output h is a handle to an hggroup.)

Changes in Finding Contour Label Handles

The documentation in R2010a noted 'clabels' as the string to use in finding contour

labels. This is incorrect and should be 'clabel'. The documentation has been changed

to 'clabel' in R2010b.

Syntax Changes for contourcmap

In previous releases, the contourcmap function had the following syntax:

contourcmap(cdelta,cmapstr)

Now, contourcmap accepts the colormap string by itself:

contourcmap(cmapstr)

Or the colormap string with cdelta:

contourcmap(cmapstr,cdelta)

Notice that the position of the two input arguments has changed. The cdelta argument

now appears after the colormap string.

In addition to this change in syntax, the contourcmap function exhibits some changes in

behavior:

1 2 ... 74 75 76 77 78 79 80 81 82 83 84 ... 159 160
