pwc_plot_2d, an Octave code which plots piecewise constant data of a 2D argument.
We assume the user has a rectangular grid of cells in the X and Y dimensions, and a Z value assigned to each cell. This library can make a graphic representation of the piecewise constant Z function using flat patches, or 3d bars.

pwc_plot_2d is available in a Matlab version and an Octave version.
box_display, an Octave code which displays a box plot, over integer pairs of data, of a function defined by two formulas.
box_plot, an Octave code which displays a box plot of data that consists of pairs of integers;
cc_display, an Octave code which displays the points used in a 2D Clenshaw-Curtis quadrature rule;
circle_grid_display, an Octave code which reads a matrix of integers, and draws a corresponding grid of circles filled with color.
grf_display, an Octave code which reads a GRF file defining a mathematical graph and displays it.
grid_display, an Octave code which reads a file of points on a grid or sparse grid, displays the grid and saves the image in a Portable Network Graphics (PNG) file;
histogram_display, an Octave code which makes a bar plot of a set of data stored as columns in a file; the first column is the X values, and all the other columns are Y values to be shown as a stack of bars;
pwc_plot_1d, an Octave code which converts the definition of a piecewise constant function of a 1D argument into plottable data.
