plot2d4

2D plot (arrows style)

Calling Sequence

plot2d4([logflag,] x,y,[style,strf,leg,rect,nax])
plot2d4(y)
plot2d4(x,y <,opt_args>)

Arguments

:args see plot2d for a description of parameters. :

Description

plot2d4 is the same as plot2d but curves are plotted using arrows style. This can be useful when plotting solutions of an ODE in a phase space.

By default, successive plots are superposed. To clear the previous plot, use clf().

Enter the command plot2d4() 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.

Sample

Examples

// compare the following with plot2d1
x=[0:0.1:2*%pi]';
plot2d4(x,[`sin`_(x) `sin`_(2*x) `sin`_(3*x)])
`clf`_()
`plot2d`_(x,[`sin`_(x) `sin`_(2*x) `sin`_(3*x)])
e=`gce`_();
e.children(1).polyline_style=4;
e.children(2).polyline_style=4;
e.children(3).polyline_style=4;
