[Paraview] Plot Maximum Value over Time

[Jeffrey Martin]

Hi, I was wondering if you could give me some advice:

I extracted some points from a clip plane with the extract data selection feature 
and we want to plot the maximum value (speed in this case) of these points over 
time.  

The extract data selection filter shows the upper and lower bounds, but we just 
need a way to plot the upper bound (i.e. maximum) over time.  I've looked online 
at spreadsheet view, but can't seem to get a definite answer.  Do you know how 
to do this?

Thank you
