showing variables in plots?

  • To: mathgroup at smc.vnet.net

  • From: Sam Waller <sam.waller at avmet.com>

I'm plotting something like this:

x = 2;

curve = Plot[...., DisplayFunction -> Identity];

txt = Graphics[ Text["x = 2", {10, 10},....] ];

Show[curve, txt, DisplayFunctio->$DisplayFunction, ...];

The problem is that I want 'txt' to automatically change if I assign a different value to x so that
I don't have to edit txt everytime I change the variable x. Something like printf() in C. Can this
be done in mathematica?

thanks,
Sam
