Pin To Axes

Hi,

I'm creating a subplot and a line notation on top.
I'm trying to pin my line to the plot and cannot find any function
that does so.

my schematic code is:

-------------------------------------------------
a = figure();
b(1) = subplot (2,1,1);
b(2) = subplot (2,1,2);
plot (b(1),[1:10:1000]);
plot (b(2),[1000:-10:1]);
anno2 = annotation('line',[0.5 0.5],[0.2 0.8]);
% <- At this stage I want to pin it...
-------------------------------------------------

of course that by right-clicking on the annotation I can perform this
but I need to do it dynamically within my function.

Is that possible?

Hi Yoav!

I assume that you are familiar with handle graphics, i.e. working
with set/get inside your code to customize plots etc. If you are not,
then read that part of the documentation. Looking at anno2 using get,
you´ll see that the only thing that happens is that two children are
added to the annotation object:

% run your posted code:
v=get(anno2,'Children')
% pin the line by right-clicking and so on ...
v2=get(anno2,'Children')

Now you can see that two more handles have been added to your stack
of Children. Take a look at them, again using get:

a1=get(v2(1))
a2=get(v2(2))

As you can see these are line object with some properties. I think
that all you´ll have to do is to find out a way to reproduce a these
lineobjects and add them as children to your annotation.

Anyway, this is just the way I would handle this.

Hi,

Thanks for replying. However, this is not working.

I saw that my annotation gets 2 new children whenever I pin it with
the right click. However, when I try to save these children's
properties, remove the pins and then load these properties again -
this is not working.

There has to be an easier way and I can't find *anything* about it on
the web or in the matlab help.

Any more ideas?

Thank you so far.
Y.

Replying to myself...

I found out that to activate the annotation matlab uses a file called
scribepin.m
I cannot find any help about this method...

Any further ideas?

Thanks again.
Y.

Hi to all

I am suffering the same problem.

Is there any func. for setting pin to axes functionality dinamically in m code?

Let explain my need for this func. maybe another solution comes without need for usage of this func. I have 2-D graph that x axis is time data and y axis is some position data. Beside this time vs position graph I need to show source of position data which can be source 1 or source 2 on the same graph. Also I need to show
state of source which can be on or off. That means I have time, position, source number and source states data to be shown on 2D graph. Is there any reommend about how to display them?

Note that Firstly I think use of double arrow for display source and source state but I need to use pin to axes for zooming functionality.

This should help to the persons interested in pinning the points to the axes (provided that people still get stuck with this):

Good luck
