The bandwidth is directly related to the sample rate of the gui block.
But understand that the GUI doesn't actually /do/ anything about the
sampling rate of the signal. It doesn't change it or really get
influenced by it. All it does is set the x-axis label.

And to zoom, you can adjust the x and y scales using the Axis Options
buttons on the left-hand side toolbar.
