Contour group objects are created by the
contour3 functions. The are equally one of the handles returned
meshc functions. The properties of the contour
contourcused to create the contours of the plot.
zlevelmodecan 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
levellistmodeis "manual", then the levels at which to plot the contours is determined by
levellistmodeis set to "auto", then the distance between contours is determined by
levelstep. If both
levelstepmodeare set to "auto", then there are assumed to be 10 equal spaced contours.
textlistmodeis "manual", then the labeled contours is determined by
textlistmodeis set to "auto", then the distance between labeled contours is determined by
textstep. If both
textstepmodeare set to "auto", then there are assumed to be 10 equal spaced labeled contours.
linestyleare similar to the corresponding properties for lines. The property
linecoloris a color property (see Colors), that can also have the values of "none" or "auto". If
linecoloris "none", then no contour line is drawn. If
linecoloris "auto" then the line color is determined by the colormap.
