Hey,  
i would like to plot data over time, it shall be represented the increasing height of an alphaphase.  
In this [Thread](https://discourse.paraview.org/t/measure-exact-the-alpha-phase-1-level/2611/8) Cory showed me, how to set up a python annotation to mesaure the hight.  
Is it possbile to show the course of the increase in a plot ?

I tried to add a the filter PlotDataOverTime, but its shows a CasePath ?!  
What kind of data is this ?! Furthermore i got only 19 time steps, it shows about 120 ?  
How can i display the height ?

Best regards  
Kai

You’ll need to save the height to a FieldData array using a **Programmable Filter** as I showed in [Measure exact the alpha.phase 1 level](https://discourse.paraview.org/t/measure-exact-the-alpha-phase-1-level/2611/6).
