This example shows how to label each contour line with its associated value.
The contour matrix,
C, is an optional output argument returned by
clabel function uses values from
C to display labels for 2-D contour lines.
Display eight contour levels of the
peaks function and label the contours.
clabel labels only contour lines that are large enough to contain an inline label.
Z = peaks; figure [C,h] = contour(Z,8); clabel(C,h) title('Contours Labeled Using clabel(C,h)')
To interactively select the contours to label using the mouse, pass the
manual option to
clabel, for example,
clabel(C,h,'manual'). This command displays a crosshair cursor when the mouse is within the figure. Click the mouse to label the contour line closest to the cursor.
