plot2d4 2D plot (arrows style)

## Syntax

    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.

## Examples

Demo: plot2d4(); plot2d4(); Examples:

    clf
    subplot(2,1,1)
    x = [0:0.1:2*%pi]';
    plot2d4(x,[sin(x) sin(2*x) sin(3*x)])

    subplot(2,1,2)
    plot2d(x,[sin(x) sin(2*x) sin(3*x)])
    e = gce();
    e.children.polyline_style=4;

subplot(2,1,1) x = [0:0.1:2*%pi]'; plot2d4(x,[sin(x) sin(2*x) sin(3*x)]) subplot(2,1,2) plot2d(x,[sin(x) sin(2*x) sin(3*x)]) e = gce(); e.children.polyline_style=4;
