I want to monitor the mass fraction of carbon dioxide, and the result is shown here, and I want to know, what are the units on the vertical axis?

The x_g are mass fractions, so they should range between 0 and 1. But I don’t know what type of monitor you defined, it could be a sum or integral which could result in any positive value. Please attach your project files - go to the main menu and click “Submit bug report” and attach the resulting zip file.

Also it would help to have a more complete screenshot (is there any other text visible in the plot?)

Thanks,
