Interactive graphs
You can use other functions to constrain Handle. For example, here is an interactive graph to demonstrate
power functions that uses Round() to prevent bad exponents and to keep the intercepts simple.
a = 3; b = 2;
New Window( "Intercepts and powers",
Graph Box(
FrameSize( 200, 200 ), X Scale( -10, 10 ), Y Scale( -10, 10 ),
Y Function( Round( b ) + x ^ (Round( a )), x );
Handle( a, b, a = x; b = y; );
Text( {a, b}, " Move me" );
Text( {-9, 9}, "y=", Round( b ), " + x^", Round( a ) );
)
);

Handle and For can be nested for complex graphs.
