Hi,

I have pp concentrations in a x=(-50,50) a 1 dimensional domain over t=(0,150) at pp.pvd file, I want to see the value of pp at the x=0 point overtime, the time evolution. **Finally my aim is to attain a “pp(0) vs t” plot.**

For doing that, I first

applied PlotOverLine filter to pp.pvd,

making the arrow passing from x=0, then

applied PlotDataOverTime to the output of PlotOverLine.

But it didn’t worked. -Maybe it is designed for 2D domains- I had an empty graph with funny numbers like …e+299.

Any ideas?

You can try selecting the point you want to plot and then use `Plot Selection Over Time` instead.

Thank you, it looks like selecting is quite handy! [6. Selecting Data — ParaView Documentation 5.8.1 documentation](https://docs.paraview.org/en/latest/UsersGuide/selectingData.html)
