15.4.6.4 Contour Groups
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 thezlevel
property. levellistmode
levellist
levelstepmode
levelstep
-
If
levellistmode
is"manual"
, then the levels at which to plot the contours is determined bylevellist
. Iflevellistmode
is set to"auto"
, then the distance between contours is determined bylevelstep
. If bothlevellistmode
andlevelstepmode
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 bytextlist
. Iftextlistmode
is set to"auto"
, then the distance between labeled contours is determined bytextstep
. If bothtextlistmode
andtextstepmode
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
andlinestyle
are similar to the corresponding properties for lines. The propertylinecolor
is a color property (see Colors), that can also have the values of"none"
or"auto"
. Iflinecolor
is"none"
, then no contour line is drawn. Iflinecolor
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.
