Matlab - fixed text size when zooming

问题:

I wish to keep the text size fixed when zooming in a plot. Thus I wish to specify the position of the 4 corners of the text-area. To explain it in other words: When the plot is zoomed out the text should hardly be visible because it is so small. Is this possible? It should be but I have not seen any solution.

As for now I am plotting a circle

rectangle('Position',[xpos, ypos, 0.06, 0.2], 'Curvature',[1,1]);
% I wish to plot textstrings of num2str(val) inside the circle here
% Another alternative, to be able to se num2str(val) whenever I click the circle

Thanks in advance

You can set the FontUnits property on the text handle to make the text scale with the axes. See here for the different possibilities.
