Plot Types

Plot Types

ParaView 3 should support the following types of queries:

• Plot of a point variable over time for a selected point
  • The point may be specified by either picking or by entering an ID
• Plot of a cell variable over time for a selected cell
  • The cell may be specified by either picking or by entering an ID
• Plot of a variable (cell or point) residing at a specific 3D location over time.
• Plot of a line probe versus position along the line
  • Sampled and interpolated when probing point variables
  • Actual values when probing cell variables
• Plot of a line probe variable versus variable using above guidelines

  I don't understand what this means. What is a probe variable and how does it differ from the position along the line?

  This means you probe say pressure and temperature and plot pressure versus temperature for all points along the line, instead of pressure versus position along the line and temperature versus position along the line

• Plot of the points/cells in the currently selected region over time

  This plot is ambiguous to me. It could mean that I select a region in 3-space and the variables in that region are plotted over time. But then what do the lines in the plot look like? You can't have a line per point or cell because they could move around over time. You could plot an envelope of values in the regions, but I'm not sure we want to tackle that kind of plot yet. The other thing this could be is that the user selects some cells with rubber band selection, and those selected points/cells are plotted over time. That makes sense, but the requirement should just be to plot the currently selected set over time.

  The intention was to grab the selected node and cell ID's and plot those node/cell ID's over time, one line per node/cell

• As part of the V&V milestone we need to be able to plot a series of values from a text file in the same plot as a 3D point over time plot.
