**NAME**

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 ofplot3dc(3plplot) (see that function's documentation for more details) should be suitable for the case where the area of thex,ycoordinate grid wherezis defined can be non-rectangular. The implementation is incomplete so the last 4 parameters of plot3dcl;indexxmin,indexxmax,indexymin, andindexymax; are currently ignored and the functionality is otherwise identical to that ofplot3dc(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 ofxvalues at which the function is evaluated.ny(PLINT, input) Number ofyvalues 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_COLORopt=DRAW_LINEX: Lines are drawn showingzas a function ofxfor each value ofy[j].opt=DRAW_LINEY: Lines are drawn showingzas a function ofyfor each value ofx[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 parametersnlevelandclevel.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 firstxindex wherezis defined.indexxmax(PLINT, input) The index value (which must be ≤nx) which corresponds (by convention) to one more than the lastxindex value wherezis defined.indexymin(const PLINT *, input) Array ofyindex values which all must be ≥ 0. These values are the firstyindex wherezis defined for a particularxindex in the range fromindexxmintoindexxmax-1. The dimension ofindexyminisindexxmax.indexymax(const PLINT *, input) Array ofyindex values which all must be ≤ny. These values correspond (by convention) to one more than the lastyindex wherezis defined for a particularxindex in the range fromindexxmintoindexxmax-1. The dimension ofindexymaxisindexxmax.
