Mouse Clicks on Graph Objects

  The analysis graphs (on the right side of the main window) and the particle view graph (upper left of screen) are independent objects which recognize and respond to mouse clicks.

Holding the left mouse button down in any of these graph objects displays a ``coordinate reader'' in the lower left corner of the respective graph. The coordinate reader is useful for reading numeric values from graphs.

Double-clicking or clicking the right mouse button prompts a pop-up menu in the upper-left corner of the graph. The ``State Graph'' and ``Particle Graph'' pop-up menus allow the user to:

• choose the Graph Type
  • Time Series--- appropriate data may be graphed as a function of time. If the user attempts to graph an item for which data is not being collected, TrapApp ignores the command.
  • Phase Space...--- allows the user to graph an arbitrary data vector y vs. an arbitrary data vector x.
  • FFT--- performs a Fast Fourier Transform on the selected data vector.
  • option available only for the Particle Graph: Poincare: r when r-momentum = 0--- plots the radial position of the tagged ion when its radial momentum is zero.
  • options available only for the State Graph: Pair Distribution, Total Displacement Distribution, Radial Displacement Distribution, Axial (z) Displacement Distribution--- these distribution functions are explained under the State Data menu item.
• Inspect Scale--- user may set the scale and axes tics for the graph object. The graph object may also be cloned; a cloned graph object is an independent window with its own inspector for setting the scale. Alternately, the graph object may be copied to an archive, in which case its data is saved in a memory buffer for recall when the user selects Paste From Archive from the Inspect Scale option.

• Projection--- project particle positions onto the XY, XZ, or YZ plane.
• Inspect Scale...--- customize the scale of the window or clone the graph.
• Tag Particle--- ``tag'' a particle by clicking on it; the tagged particle is the one monitored in Particle Data selections.
