MATLAB: Annotate the lines in plot with many line

annotate the line in plotannotate the plotinclude annotations in a codelabel the lines in a plot

Hello everyone, I am trying to annotate a plot which contains many line. The annotation data has to come from a vector suitable to each line. I am including the plot which I am trying to annotate. Is there a way by which I can write a code to label or annotate these lines. Thank you in advance!

See example there and the "See Also" for annotation for more exotics...

To include brackets, you could use for example, a=mat2str(B(1,:)). Or n=num2str(B,'[%5.3g],'), or str=['[',num2str(3),']']

To add an arrow, use annotation('arrow') or annotation('doublearrow')

There's nothing that ships with MATLAB that does exactly what you want. The 'doublearrow' annotation is probably the thing that comes the closest. It can be used to indicate a distance in a plot, but it's clearly not a brace.

If you're really committed to having a brace, I would just draw some kind of brace-like shape using the line command. The task then becomes generating x-data and y-data that define your brace. This can be as simple or as complicated as you like. Here's one idea:

% Here's the plot I'm annotating
plot(1:10)
% These define the placement and size of the brace
x = 6;
y1 = 0;
y2 = 6;
width = 0.2;
% Make some x-data and y-data
line_x = x  + [0, 0.5, 0.5, 1, 0.5, 0.5, 0]*width;
line_y = y1 + [0, 0.02, 0.48, 0.5, 0.52, 0.98, 1]*(y2-y1);
% Draw the brace and some text, too, for fun.
line(line_x, line_y, 'Color', 'k')
text(x+1.5*width, y1 + 0.5*(y2-y1), 'Whoaaa! Look at this gap!');

You can see that's a relatively primitive brace. If I wanted to make it fancier, I might start looking at using Bézier curves.
