Plot Over Line (ProbeLine)
Sample data attributes at the points along a line. Probed lines will be displayed in a graph of the attributes.
The Plot Over Line filter samples the data set attributes of the current data set at the points along a line. The values of the point-centered variables along that line will be displayed in an XY Plot. This filter uses interpolation to determine the values at the selected point, whether or not it lies at an input point. The Probe filter operates on any type of data and produces polygonal output (a line).
