labelplot

Adds plot legend based on 'Tag'

Description

This short function will generate a legend based on 'Tag' information given by plot. A legend title is also possible.

figure; hold on; x = 1:10; plot(x,x,'Tag','Positive'); plot(x,-x,'Tag','Negative'); labelplot('eo','v','Slope');

The above example is equivalent to
  legend('Positive','Negative')
and adding a text box 'Slope' above it.

• MATLAB release: MATLAB 7.2 (R2006a)

Fantastic - just what I was looking for! Generates perfect legends which does not require me to specify a fixed number of plot lines! Thanks!
