Text in a patch

Hello,

I have a problem which seems simple but I cannot find an easy way to solve it.

I create a lot of patches (hexagons) in a plot, and I have to display an information inside each patch. The problem is that number of patches can vary a lot, and I have to be able to read the information well. The other thing that I want is to have the text size increased when I resize the window (as the patches do), so I want to use normalized units.

Right now it is like that :

x=xcoordinates;
y=ycoordinates;
c=values;
for i=1:length(x)
        p=patch(x(i),y(i),c(i));
        tx=text(x(i), y(i), num2str(c(i)),'HorizontalAlignment','center','VerticalAlignment','middle','FontUnits', 'Normalized', 'FontSize', 0.1);
        hold on
end

I would like to use the normalized size "size" that has each patch "p" to create a text "tx" and adapt the font size "fsize" to this "size".

Do you know a straightforward way to do this?

Thanks!

I used to set userdata for text objects reflecting relative font size. Then when I got a figure resize callback, I would figure out the base size and findobj() to get the text objects with the special marks and use the information there to modify the computed base font size.

I used this approach instead of a plain set(findobj('type', 'text'), 'fontsize', X) in order to allow for headers (larger than normal) and explanatory text (smaller)

Though really what I did was use this marking process along with a user font size preference, changing all the objects when the user modified their preferences. I also implemented dynamic uisizing and text wrapping so that as the user made the text larger the boxes did not overflow. The logical also auto positioned controls according to a system of layout rules.

... Basically my boss used a different sized monitor with different sized pixels and configuring against their monitor would have had the interface look crappy for everyone else, so I did autolayout to make everyone happy.

Autolayout is harder to make look good than you might think!

Thank you very much for your answer! However, I don't succeed to do it, would you have an example with my code ?
