legends — draw graph legend
legends(strings,style [,opt]) legends(strings,style,xy)
| 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 |
| ||||||||
| xy | : a vector [x,y] which gives the coordinates of the upper left corner of the legend box. |
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.
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]])
