Label Contour Plot Levels
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.
