Contour group objects are created by the contour
, contourf
, and contour3
functions. They are also one of the handles returned by the surfc
and meshc
functions. The properties of the contour group are
contourmatrix
A read only property that contains the data return by contourc
used to create the contours of the plot.
fill
A radio property that can have the values "on"
or "off"
that flags whether the contours to plot are to be filled.
zlevelmode
zlevel
The radio property zlevelmode
can have the values "none"
, "auto"
, or "manual"
. When its value is "none"
there is no z component to the plotted contours. When its value is "auto"
the z value of the plotted contours is at the same value as the contour itself. If the value is "manual"
, then the z value at which to plot the contour is determined by the zlevel
property.
levellistmode
levellist
levelstepmode
levelstep
If levellistmode
is "manual"
, then the levels at which to plot the contours is determined by levellist
. If levellistmode
is set to "auto"
, then the distance between contours is determined by levelstep
. If both levellistmode
and levelstepmode
are set to "auto"
, then there are assumed to be 10 equal spaced contours.
textlistmode
textlist
textstepmode
textstep
If textlistmode
is "manual"
, then the labeled contours is determined by textlist
. If textlistmode
is set to "auto"
, then the distance between labeled contours is determined by textstep
. If both textlistmode
and textstepmode
are set to "auto"
, then there are assumed to be 10 equal spaced labeled contours.
showtext
Flag whether the contour labels are shown or not.
labelspacing
The distance between labels on a single contour in points.
linewidth
linestyle
linecolor
The properties of the contour lines. The properties linewidth
and linestyle
are similar to the corresponding properties for lines. The property linecolor
is a color property (see Colors), that can also have the values of "none"
or "auto"
. If linecolor
is "none"
, then no contour line is drawn. If linecolor
is "auto"
then the line color is determined by the colormap.
xdata
ydata
zdata
The original x, y, and z data of the contour lines.
xdatasource
ydatasource
zdatasource
Data source variables.
