plot2d2 — 2D plot (step function)
plot2d2([x],y) plot2d2([x],y,<opt_args>) plot2d2([logflag],x,y,[style,strf,leg,rect,nax])
plot2d2 is the same as plot2d but the
functions given by (x,y) are supposed to be piecewise
constant.
By default, successive plots are superposed. To clear the previous
plot, use clf().
Enter the command plot2d2() to see a demo. Note that all
the modes proposed by plot2dxx (xx = 1 to 4) can be enabled
using plot2d and setting the polyline_style
option to the corresponding number.
