Detailed Description

Different figures can created simultaneously.

They are characterized by the label nfig.

void plot_close_all (   ) 
 

Closing all opened figures.

xx Array (size: np ) of abscissas of the points
yy Array (size: np ) of ordinates of the points
color color of the small circles: see color_list

Drawing a profile with uniform x sampling.

A profile is a curve y=y(x). It is drawn on the specified figure. If the latter is not opened, it will be opened with the device name device provided by the last argument.

Parameters:
yy Array (size: nx ) of y values to be drawn (the x sampling is supposed to be uniform in [-1,1]).
nx Number of points
color color of the profile: see color_list
style style of the profile: the possible values are line_style[i] = 1 (full line), 2 (dashed), 3 (dot-dash-dot-dash), 4 (dotted), 5 (dash-dot-dot-dot).
nfig index of the figure (in the range [0,99]) to be used for the plot: if this figure does not exist, it will be created with the device name device provided by the last argument.
ymin lower bound on y of the graphical window (used only if a new figure must be created)
ymax upper bound on y of the graphical window (used only if a new figure must be created)
title title of the figure (used only if a new figure must be created)
label_y y legend of the figure (used only if a new figure must be created)
device type of graphical device (default value = 0x0, will result in interactive choice) (used only if a new figure must be created)
