how to plot over line with the horizontal

ParaView Support

Hello everyone, I would like to ask, I have obtained the average data of a horizontal slice, and now I would like to obtain the variation of this data along the height. How should I proceed

Hi,

Did you try the Plot Over Line filter ?

Plot over line can only obtain data on one line, but I want to obtain data on the variation of a layer or surface with height.

Or rather, how did you operate it，thank you for your reply

Not sure to follow. Do you mean: you slice at several positions, compute the mean on each slice and then try to get the diff between slices ?

If not can you share some detailed steps, and possibly data / screenshot ?

Yes, it’s like this, but it’s very difficult to manually select a few slices of different heights, and if I want to get the average value of slices changing with height, I have to select 300 slices of different heights. So, it’s very difficult. Is there any simple method

Not sure how to do that. Two ideas to explore:

  • GenerateTimeSteps on your data, move the slice (create an animation) and then PlotDataOverTime
  • Create a multi-slice with Slice and a value-range. Do some python code with Programmable Filter (can use a Connectivity to identify each slice).

Thank you for your reply. I will study the two methods you mentioned
