### Calling Sequence

  `legends(strings,style [,opt])`
  `legends(strings,style,xy)`
  ``

### Parameters

- `strings` : n vector of strings, strings(i) is the legend of the ith curve
- `style :` integer row vector of size n (the plot styles, third parameter of plot2d) or an integer 2 x n matrix, style(1,k) contains the plot style for the kth curve and style(2,k) contains the line style (if style(1,k)>0) or mark color (if style(1,k)<0).
- `opt`

- `1` = Upper right-hand corner 2 = Upper left-hand corner
- `3` = Lower left-hand corner
- `4` = Lower right-hand corner
- `5` = Interactive placement with the mouse (default)

- `xy` : a vector [x,y] which gives the coordinates of the upper left corner of the legend box.

### Description

Puts a legend on the current plot using the specified strings as labels.

In the interactive placement (opt=5) move the legend box with the mouse and press the left button to release it.

This function allow more flexible placement of the legends than the leg plot2d argument.

### Examples

    t=0:0.1:2*%pi;
    plot2d(t,[cos(t'),cos(2*t'),cos(3*t')],[-1,2 3]);
    legends(['cos(t)';'cos(2*t)';'cos(3*t)'],[-1,2 3],4)
    xset("line style",2);plot2d(t,cos(t),style=5);
    xset("line style",4);plot2d(t,sin(t),style=3);
    legends(["sin(t)";"cos(t)"],[[5;2],[3;4]])
