Hi, everyone.

After applying a Slice filter, I further execute a series of filters and then apply Integrate Variables filter to obtain two integrated values (which are scalar).

I wanna do further calculation on the integrated values, say one integrated value divided by another value. In Paraview, it doesn't allow me to apply Calculator filter to operate the integrated values (pls correct me if i missed sth).

One approach is to export the value as csv file, and do the calculation in excel, but it is not a user friendly way. my question is how to operate the integrated values directly in Paraview, without exporting to csv.

Hope someone here can help. Many thanks in advance.

You can use Calculator filter with the integrated values.

can you tell more how to operate calculator filter to handle two "separated" integrated values; whilst "separated" means that the integrated values come from different series of preceding filters? i tried but no "separated" integrated values can be chosen at a single calculator filter.

i found append attributes work in my case. but, when i try to further do the plot selection over time, the results are strange that the variable title and the values are mismatching and some values are missing.

anyone can suggest alternative workaround?

I would use Python and fetch the integrated values and plot them with matplotlib. Here is an example script: Integral average of velocity values on a slice
