Hello everybody!

I had a problem with the complex using of two filters - "Threshold Filter" and "Integrate Variables".
For now I'm trying to use "Threshold Filter" to extract concentration of fluid (alpha) in computational domain (2D). So, it work's great.
By next step, I apply "Plot over line" filter to extract some line on this "Threshold Filter". So, it work's)
But, on the next step, when I apply "Integrate Variables" of this "Plot" on "Threshold", I have "nan" value for parametres like "Ux, Uy, alpha, p".

You can see my problem on screenshot.

What I need to do to make it work?

Best regards,
