Requirements

• I searched through the issues if the issue already exists

Steps to reproduce

1. Open the attached project:project.lml
2. Remove the last data row.

Expected

The plot should be automatically updated to reflect the changes in data source (i.e. the spreadsheet).

Observed

The plot is not being updated.
