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

[ ] : see plot2d for a description of 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 xbasc().

Enter the command plot2d2() to see a demo.

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]';
xbasc()
plot2d2(x,[sin(x) sin(2*x) sin(3*x)])
