plmeshc: Magnitude colored plot surface mesh with contour

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

A more powerful form of plmesh: 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.

x (PLFLT_VECTOR, input)

A vector containing the x coordinates at which the function is evaluated.

y (PLFLT_VECTOR, input)

A vector containing the y coordinates at which the function is evaluated.

z (PLFLT_MATRIX, input)

A matrix containing function values to plot. Should have dimensions of nx by ny.

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 current cmap1.

  • 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_VECTOR, input)

A vector containing the contour levels.

nlevel (PLINT, input)

Number of elements in the clevel vector.

Redacted form: plmeshc(x, y, z, opt, clevel)

This function is used in example 11.
