The filter is now called "Plot Selection over time". Go to
"View | Selection Inspector" and create a new selection with "Selection 
Type": "Location" to create a location based selection. Then, create 
"Plot Selection over time" and copy the active selection to it.

One possibility is apply the Calculator to the output of the "Plot 
Selection Over Time" filter. However, you'll have to hard code the 
position at time 0 in the equation for the calculator to compute the 
displacement.
