Display a plot by clicking a button

Ok, this seems to be very easy in Mathematica.

Button["Show me a plot", Show[Plot[Sin[x], {x, -Pi, Pi}]]]

Then you click the button, nothing happens.

Button["Show me a plot", Print[Plot[Sin[x], {x, -Pi, Pi}]]]

This line will do the job. Or use the following line:

Show[Plot[Sin[x], {x, -Pi, Pi}],
DisplayFunction -> (Button["Show me a plot", Print[#]] &)]

The key here is to use “Print” rather than “Show”. It isn’t clearly explained in the “ref/Button”.

It is kind of intuitive, because the second argument is an action. And it says "evaluates action whenever it is clicked". If you type in ?Button you will see a quick help.
