There are a few ways to create a progress bar based on all the empty fields in a form view. 

One approach would be to set up a custom formula field in the form view. In this formula field, you would define a formula based on the number of empty fields versus the total number of fields. Depending on the platform you are using, the specific syntax and calculations may vary, but the concept should remain the same. 

Alternatively, you could also make use of a platform-specific automation tool or feature to calculate the percentage of empty fields automatically and display the corresponding progress bar. Refer to the platform's documentation for more information about setting up such an automation. 

I hope this helps!
