Drawing Text in a Box

When you use the text command to display a character string, the string's position is defined by a rectangle called the Extent of the text. You can display this rectangle either as a box or a filled area. For example, you can highlight contour labels to make the text easier to read.

[x,y] = meshgrid(-1:.01:1);
z = x.*exp(-x.^2-y.^2);;
[c,h]=contour(x,y,z);
h = clabel(c,h);
set(h,'BackgroundColor',[1 1 .6])

For additional features, see the following text properties:

BackgroundColor -- Color of the rectangle's interior (none by default)

EdgeColor -- Color of the rectangle's edge (none by default)

LineStyle -- Style of the rectangle's edge line (first set EdgeColor)

LineWidth -- Width of the rectangle's edge line (first set EdgeColor)

Margin -- Increase the size of the rectangle by adding a margin to the text extent.
