Now that contourfm produces correct results more consistently, it also takes somewhat
longer to run.
clabelm No Longer Breaks Contour Lines
In previous releases, the clabelm function broke contour lines to display the contour
level tag. The breaks failed to scale appropriately during zooming or when the figure size
changed. Now, instead of breaking the contour line, the clabelm function sets the color
of the background where the tag is inserted to the color of the ancestor axes or line.
Compatibility Considerations
If you want to display the contour labels without a background color, as in previous
releases, use set to specify 'BackgroundColor','none' on the text object handle array
returned by clabelm.
Changes in geoshow Behavior with 'DisplayType','contour'
Many aspects of the fix to Bug 192285 apply to geoshow contouring options as well as
to contourm. When applied to a data grid with the DisplayType parameter set to
'contour', geoshow now contours the grid in the same way that contourm would,
constructs a handle to the same sort of hggroup, and accepts the same set of optional
parameters (as documented on the contourm reference page).
Compatibility Considerations
When used with 'DisplayType','contour' in previous releases, geoshow
constructed a MATLAB contourgroup and returned its handle. In previous releases, you
could set any contourgroup property via geoshow (possibly with unexpected results); you
can now set only the parameters described in the contourm reference page—a useful,
relevant, and validated subset.
Changes in geoshow Behavior with 'DisplayType','surface'
When applied to a data grid with the 'DisplayType' parameter set to 'surface',
geoshow now sets the 'FaceColor' property to 'interp', unless the 'CData'
property is also passed into the function. In that case, the 'FaceColor' is set to
'texturemap'.
