# 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.

### 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;```
