{alias:con}
h2. Name
*con* — Contour dataset using scalars
h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#FFFFAA}
*con i | v | s | n | ms | l* \[*noadj*] \[*sav*]
{panel}
h2. Description
Contor dataset with lines following the scalar values.
h2. Arguments
h4. Main contouring arguments:
Note that the main contouring arguments are the same for other shell commands that contour in various ways.
*i* _incr_
{indent} _incr_ is the increment value.
{indent}
*v* _val1_ \[_val2_ _val3_ ...\]
{indent} Contour at specific values, _val1_, _val2_, ...
{indent}
*s* _start increment stop_
{indent} *s* for step needs three numbers: _start_, _increment_ and _stop_ The first and last contour will be at _start_ and _stop_.
{indent}
*n* _number_
{indent} Use _number_ contours (levels), equally distributed between the minimum and maximum value.
{indent}
*ms* _start1 incr1 stop1 start2 incr2 stop2_
{indent} *ms* for multiple steps needs six following numbers. The first contour will be at _start1_, the last at _stop2_.
{indent}
*l*
{indent} Use levels from the last previous contouring operation.
{indent}
*noadj*
{indent} 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.
{indent}
*sav* \[*nodraw*]
{indent} 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.
