Name
con — Contour dataset using scalars
...
Note that the main contouring arguments are the same for other shell commands that contour in various ways.
i incr
incr is the increment value.
v val1 [val2 val3 ...]
Contour at specific values, val1, val2, ...
s start increment stop
s for step needs three numbers: start, increment and stop The first and last contour will be at start and stop.
n number
Use number contours (levels), equally distributed between the minimum and maximum value.
ms start1 incr1 stop1 start2 incr2 stop2
ms for multiple steps needs six following numbers. The first contour will be at start1, the last at stop2.
l
Use levels from the last previous contouring operation.
noadj
The contours will, by default, be lifted up (or adjusted) a little bit for better visualization. This can be prevented with the noadj argument. Use this argument for contouring vertical surfaces like cross sections.
sav [nodraw]
Will save the contours in active and in workspace under the name ^con which is not directly visible. If the sav argument is used in a command menu which restores the original active data, the user must make it active by mlo ^con. The nodraw argument prevents the contours to be drawn on the screen.
