PLMESHC(3plplot) PLplot API PLMESHC(3plplot)NAME

plmeshc - Magnitude colored plot surface mesh with contour.SYNOPSIS

plmeshc(x, y, z, nx, ny, opt, clevel, nlevel)DESCRIPTION

Identical to plmesh but with extra functionalities: the surface mesh can be colored accordingly to the current z value being plotted, a contour plot can be drawn at the base XY plane, and a curtain can be drawn between the plotted function border and the base XY plane. Redacted form: plmeshc(x, y, z, opt, clevel) This function is used in example 11.ARGUMENTS

x (PLFLT *, input) Pointer to set of x coordinate values at which the function is evaluated. y (PLFLT *, input) Pointer to set of y coordinate values at which the function is evaluated. z (PLFLT **, input) Pointer to a vectored two-dimensional array with set of function values. nx (PLINT, input) Number of x values at which function is evaluated. ny (PLINT, input) Number of y values at which 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 cur- rent colormap 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 (PLFLT *, input) Pointer to the array that defines the contour level spacing. nlevel (PLINT, input) Number of elements in the clevel array.AUTHORS

PLSURF3D(3plplot) PLplot API PLSURF3D(3plplot)NAME

plsurf3d - Plot shaded 3-d surface plotSYNOPSIS

plsurf3d(x, y, z, nx, ny, opt, clevel, nlevel)DESCRIPTION

Plots a three dimensional shaded surface plot within the environment set up by plw3d(3plplot). The surface is defined by the two-dimen- sional array z[nx][ny], the point z[i][j] being the value of the function at (x[i], y[j]). Note that the points in arrays x and y do not need to be equally spaced, but must be stored in ascending order. For further details see the PLplot documentation. Redacted form: plsurf3d(x, y, z, opt, clevel) This function is not used in any examples.ARGUMENTS

x (PLFLT *, input) Pointer to set of x coordinate values at which the function is evaluated. y (PLFLT *, input) Pointer to set of y coordinate values at which the function is evaluated. z (PLFLT **, input) Pointer to a vectored two-dimensional array with set of function values. nx (PLINT, input) Number of x values at which function is evaluated. ny (PLINT, input) Number of y values at which 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. FACETED + SURF_CONT opt=FACETED: Network of lines is drawn connecting points at which function is defined. opt=BASE_CONT: A contour plot is drawn at the base XY plane using parameters nlevel and clevel. opt=SURF_CONT: A contour plot is drawn at the surface plane using parameters nlevel and clevel. opt=DRAW_SIDES: draws a curtain between the base XY plane and the borders of the plotted function. opt=MAG_COLOR: the surface is colored according to the value of Z; if MAG_COLOR is not used, then the default the surface is colored according to the intensity of the reflected light in the surface from a light source whose position is set using pllight- source(3plplot). clevel (PLFLT *, input) Pointer to the array that defines the contour level spacing. nlevel (PLINT, input) Number of elements in the clevel array.AUTHORS
