Summary New Behavior Compatibility Considerations
Contours
separating
filled areas
By default, the contourfm
function now draws black contour
lines to separate filled areas of
different colors.
In previous releases, the function
did not draw lines by default.
To suppress the lines, specify
'LineColor','none'.
Border of data When 'LineColor' is set to a
value other than 'none', the
contourfm function no longer
draws lines around the boundary
of the data. The data boundary is
not a contour, so it is not treated as
such. The only lines drawn are true
contours.
In previous releases, the function
drew lines around the boundary of
the data, in addition to the contour
lines themselves.
Line colors If you set 'LineColor' for
contourm or contour3m to
'auto' or 'flat', the line colors
come from the figure's colormap,
as always. But, as of R2010b, if
you change the figure's colormap
after creating the contours, the line
colors do not change.
In previous releases, if you changed
the figure's colormap after creating
the contours, the line colors
changed. To change the line colors,
use contourcmap.
Fill colors When you call contourfm, the fill
colors are derived from the figure's
colormap, as in previous releases.
As of R2010b, if you change the
figure's colormap after calling
contourfm, the fill colors are not
affected.
To change the fill colors after
plotting the filled contours, call
contourcmap.
Globe map
display
You can now use the globe
map display with the contouring
functions. The contour3m function
warns, but if you are careful to
scale your input data correctly
relative to the radius of your
reference sphere, you can still use
it.
In previous releases, you could not
use the globe map display with
the contouring functions.
