                  4 %   H = NEWPLOT(HSAVE) prepares and returns an axes, but does not
                  5 %   delete any objects whose handles appear in HSAVE. If HSAVE is
                  6 %   specified, the figure and axes containing HSAVE are prepared
                  7 %   instead of the current axes of the current figure. If HSAVE is

                 10 %   NEWPLOT is a standard preamble command that is put at
                 11 %   the beginning of graphics functions that draw graphs
                 12 %   using only low-level object creation commands. NEWPLOT
                 13 %   "does the right thing" in terms of determining which axes and/or
                 14 %   figure to draw the plot in, based upon the setting of the
                 15 %   NextPlot property of axes and figure objects, and returns a
                 16 %   handle to the appropriate axes.

                 19 %
                 20 %   First, prepare a figure for graphics:
                 21 %   Clear and reset the current figure using CLF RESET if its NextPlot
                 22 %   is 'replace', or clear the current figure using CLF if its
                 23 %   NextPlot is 'replacechildren', or reuse the current figure as-is
                 24 %   if its NextPlot is 'add', or if no figures exist, create a figure.
                 25 %   When the figure is prepared, set its NextPlot to 'add', and then
                 26 %   prepare an axes in that figure:
                 27 %   Clear and reset the current axes using CLA RESET if its NextPlot
                 28 %   is 'replace', or clear the current axes using CLA if its NextPlot
                 29 %   is 'replacechildren', or reuse the current axes as-is if its
                 30 %   NextPlot is 'add', or if no axes exist, create an axes.
