# plot3dcl.3plplot man page

**plot3dcl** — Magnitude colored plot surface with contour for z[x][y] with y index limits

## Synopsis

**plot3dcl**(*x*, *y*, *z*, *nx*, *ny*, *opt*, *clevel*, *nlevel*, *indexxmin*, *indexxmax*, *indexymin*, *indexymax*)

## Description

When the implementation is completed this variant of **plot3dc**(3plplot) (see that function's documentation for more details) should be suitable for the case where the area of the *x*, *y* coordinate grid where *z* is defined can be non-rectangular. The implementation is incomplete so the last 4 parameters of plot3dcl; *indexxmin*, *indexxmax*, *indexymin*, and *indexymax*; are currently ignored and the functionality is otherwise identical to that of **plot3dc**(3plplot).

Redacted form: General: **plot3dcl(x, y, z, opt, clevel, indexxmin, indexymin, indexymax)** Perl/PDL: Not available?

This function is not used in any example.

## Arguments

*x*(const PLFLT *, input)- Pointer to set of x coordinate values at which the function is evaluated.
*y*(const PLFLT *, input)- Pointer to set of y coordinate values at which the function is evaluated.
*z*(const PLFLT * const *, input)- Pointer to a vectored two-dimensional array with set of function values.
*nx*(PLINT, input)- Number of
*x*values at which the function is evaluated. *ny*(PLINT, input)- Number of
*y*values at which the function is evaluated. *opt*(PLINT, input)- Determines the way in which the surface is represented. To specify more than one option just add the options, e.g. DRAW_LINEXY + MAG_COLOR
*opt*=DRAW_LINEX : Lines are drawn showing*z*as a function of*x*for each value of*y*[j] .*opt*=DRAW_LINEY : Lines are drawn showing*z*as a function of*y*for each value of*x*[i] .*opt*=DRAW_LINEXY : Network of lines is drawn connecting points at which function is defined.*opt*=MAG_COLOR : Each line in the mesh is colored according to the z value being plotted. The color is used from the current color map 1.*opt*=BASE_CONT : A contour plot is drawn at the base XY plane using parameters*nlevel*and*clevel*.*opt*=DRAW_SIDES : draws a curtain between the base XY plane and the borders of the plotted function. *clevel*(const PLFLT *, input)- Pointer to the array that defines the contour level spacing.
*nlevel*(PLINT, input)- Number of elements in the clevel array.
*indexxmin*(PLINT, input)- The index value (which must be ≥ 0) that corresponds to the first
*x*index where*z*is defined. *indexxmax*(PLINT, input)- The index value (which must be ≤
*nx*) which corresponds (by convention) to one more than the last*x*index value where*z*is defined. *indexymin*(const PLINT *, input)- Array of
*y*index values which all must be ≥ 0. These values are the first*y*index where*z*is defined for a particular*x*index in the range from*indexxmin*to*indexxmax - 1*. The dimension of*indexymin*is*indexxmax*. *indexymax*(const PLINT *, input)- Array of
*y*index values which all must be ≤*ny*. These values correspond (by convention) to one more than the last*y*index where*z*is defined for a particular*x*index in the range from*indexxmin*to*indexxmax - 1*. The dimension of*indexymax*is*indexxmax*.
