| There are multiple ways of probing a data set for point or cell values. The simplest
| | {{ParaView/Template/DeprecatedUsersGuide}} |
| is the Probe Location filter. Additionally, there are a variety of filters
| |
| to plot data with respect to time, location, or grid object Id.
| |
| | |
| === Probe Filter ===
| |
| The probe filter can be used to query a data set for point or cell data.
| |
| | |
| Options for the probe filter are:
| |
| * Show point button is used to show where the center of the sphere is for generating the probe points.
| |
| * Center on bounds will place the sphere center at the center of the data set's bounds.
| |
| * The sphere center can either be set in the properties tab of the object inspector or in the 3d view with the mouse cursor. To choose a new point in the 3d view window, press P and then click on the desired point. Note that the Show Point option must be selected in order to activate the point widget.
| |
| | |
| The output for this filter is a single cell comprised of a set of points in a vtkPolyData.
| |
| | |
| == Line Plots ==
| |
| The line plots have similar control functionality for displaying the results.
| |
| These options are in the Display tab of the Object Inspector and include selecting
| |
| which point and/or cell data to include in the plot, what should be used as the
| |
| x axis values (e.g. point/cell index or a specified point or cell data array),
| |
| and plot preferences such as line thickness and marker style.
| |
| | |
| | |
| === Plot Data / Scatter Plot ===
| |
| The Plot Data filter and Scatter Plot filter are very similar in functionality
| |
| with the Scatter Plot filter being a deprecated version of the Plot Data filter.
| |
| The main difference is that the Scatter Plot filter's output is a 1D rectilinear
| |
| grid while the Plot Data filter's output is the same type as the input.
| |
| | |
| The Plot Data filter plots point or cell data over the entire data set. By default
| |
| the x axis values are determined with respect to their point or cell index.
| |
| | |
| === Plot Over Line ===
| |
| The Plot Over Line filter is used to plot point data over a specified straight line.
| |
| The Plot Over Line filter will not display cell data over the line so the user can use the
| |
| Cell Data to Point Data filter to convert cell data to point data in order to use this filter
| |
| for viewing desired cell data.
| |
| The line geometry can specified either by setting the points in the Properties tab
| |
| of the Object Inspector or by pressing P and selecting the beginning and ending points
| |
| of the line. Note that the Show Line option must be selected to activate the line widget.
| |
| The resolution option is used to specify at how many evenly spaced points on the line to query
| |
| the data set for information the point data to plot with respect to.
| |
| | |
| === Plot on Sorted Lines ===
| |
| | |
| The Plot on Sorted Lines filter is used when polydata with line cell types have been extracted from
| |
| a data set and the user wants to see how point data varies over the line. This filter orders the
| |
| lines by their connectivity instead of their point index. The output of the filter is a multiblock
| |
| with a block for each contiguous line.
| |
| | |
| === Plot on Intersection Curves ===
| |
| | |
| === Plot Selection Over Time ===
| |
| | |
| === Plot Global Variables Over Time ===
| |
