contour¶
Library¶
pgraph
Format¶
-
contour(x, y, z)¶ Parameters: - x (1xK vector) – the X axis data. K must be odd.
- y (Nx1 vector) – the Y axis data. N must be odd.
- z (NxK matrix) – the matrix of height data to be plotted.
Global Input¶
-
\_plev Kx1 vector, user-defined contour levels for contour. Default 0.
-
\_pzclr Nx1 or Nx2 vector. This controls the Z level colors. See
surface()for a complete description of how to set this global.
Remarks¶
A vector of evenly spaced contour levels will be generated automatically
from the z matrix data. Each contour level will be labeled. For
unlabeled contours, use ztics().
To specify a vector of your own unequal contour levels, set the vector
_plev before calling contour().
To specify your own evenly spaced contour levels, see ztics().
