Scilab Function legends - draw graph legend
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]])
