The Data Analysis filter uses the VTK filter vtkDataAnalysisFilter. The filter samples point data at a cell, point, line, cell ID, or point ID.

  1. First the user selects the data they wish to operate on from the Selection Window. It will be highlighted yellow when this occurs.
  2. The user can then select Filter->Alphabetical->Data Analysis from the main menu, or click on the ParaViewDataAnalysisButton.png Button.
  3. Initially the Data Analysis filter allows the user to:
    1. Pick the Query method (cell, point, line, cell ID, or point ID).
    2. Pick the Position of the point widget.
    3. Toggle the visibility of the point widget with the Visibility checkbox.
    4. Show the X-Y plot of the data.
  4. The Accept button must be pressed before the output will be generated.

Once the Accept button is pressed, the layout of the Data Analysis filter changes.

  1. The user can pick the query method (cell, point, line, cell id, or point id).
  2. The user can pick the position of the point widget.
  3. The user can toggle the visibility of the point widget with the Visibility checkbox.
  4. The user can show the X-Y plot of the data, change the plot title, the annotations on the X and Y axes, the legend, and plot type.
  5. The user can toggle all the Cell Scalars on/off.

The final section of the Data Analysis filter shows the type and values of scalars that are located at the point picked by the user.
