Using the Map Axes Map Limit Properties with axesm, setm, and
defaultm
Changes and enhancements have been made to axesm, setm, and defaultm with
respect to map axes properties that affect the fundamental display geometry:
• MapProjection
• Zone
• Origin
• FLatLimit
• FLonLimit
• MapLatLimit
• MapLonLimit
The changes result in the following improvements:
• The use of the map limit properties to set up a map axes is more intuitive.
• The way in which defaultm resolves possible inconsistencies between these
properties is now consistent with the behavior of axesm and setm.
• The map limit properties (MapLatLimit and MapLonLimit), the frame limit
properties (FLatLimit and FLonLimit), and the Origin, MapProjection, and
Zone properties interact in a more clear and predictable fashion.
For more information, see the section Using the Map Limit Properties in the Mapping
Toolbox User's Guide and bug report 319891 on the MathWorks Web site.
Changing Projection Type of an Existing Map Axes with setm
In previous releases, calling the setm function to change the MapProjection property
of a map axes, especially when switching between an azimuthal and non-azimuthal
projection (e.g., a conic or cylindrical projection), often resulted in the following types of
problems:
• The modified map axes might cover a different part of the Earth.
• The map frame and graticule might fail to update properly.
• Map limit properties changed at the same time as the projection might not have the
proper effect.
