Zooming in on data and obtaining profile plots

By default, zooming is on. The effect of using the mouse and selecting a point on the plotted data depends on whether zooming is on or off or if you are viewing a profile plot. Left button: Toggle turning zoom on/off. When zooming is on: Left button: Can be used either to select an area in the plot to zoom into, or it can be used to zoom into an area by a factor of 2, centered about the clicking point.

• Middle button: Returns to the default in which the entire domain is displayed provided that there is no mouse movement. If there is mouse movement, the view will pan corresponding to the mouse motion on the button release. Alternatively, the user can toggle a panning mode via pressing the `m' key.
• Right button: Zooms out by a factor of 2.
• When zooming is off: Left button: Used to select a line along which a 2-d x-z transect of the data is displayed. Note that the transect uses a simple nearest-neighbor interpolation to display the data in the transect. If you press the mouse button once in the domain while zooming is off, you may get a message that says ''Cannot plot this slice''. This occurs because the length of the transect you have chosen is effectively zero by clicking once on the plot window when zooming is off.
  • Middle button: No effect.
  • Right button: Displays the processor number and the value of the data at the selected point.
• Middle button: No effect.
• Right button: No effect.
• Left button: This will toggle back and forth between the surface plot and the previous transect that was displayed. In the event that no transect has been displayed, the error message Need two points for a profile first! will be displayed. In this case, turn zooming off and select two points for a profile.
  • Middle button: Display the default west-east transect along the middle of the data set. This is useful when you have a channel flow in the x-direction and want to see the data in the x-z plane.
  • Right button: Display the default north-south transect along the middle of the data set. This is useful when you have a channel flow in the x-direction and want to see the cross-channel data in the x-y plane.
