plot2d2
Scilab Function

plot2d2 - 2D plot (step function)

Calling Sequence

plot2d2([x],y)
plot2d2([x],y,<opt_args>)
plot2d2([logflag],x,y,[style,strf,leg,rect,nax])

Parameters

Description

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.

Examples


// plots a step function of value i on the segment [i,i+1]
// the last segment is not drawn
plot2d2([1:4],[1:4],1,"111","step function",[0,0,5,5])
// compare the following with plot2d
x=[0:0.1:2*%pi]';
clf()
plot2d2(x,[sin(x) sin(2*x) sin(3*x)])
  // In New graphics only
clf()
set("figure_style","new")
plot2d(x,[sin(x) sin(2*x) sin(3*x)])
e=gce();
e.children(1).polyline_style=2;
e.children(2).polyline_style=2;
e.children(3).polyline_style=2;
