You are able to change the boundaries of a plot in Maple by including x=a..b and y=c..d options in the plotting command. To change the z-axis range in 3D plots you can also use view=e..f.
For Example:
plot(tan(x),x=-Pi..Pi,y=−5..5);
plot3d(sin(x) + sin(y), x = 0 .. Pi, y = 0 .. 2*Pi, view = -2 .. 2);
To change just the view of the plot without changing the plotting range you can use the option view=[a..b,c..d,e..f]
For Example:
plot3d(sin(x) + sin(y), view = [-2 .. 2, -1 .. 1, -3 .. 3]);
