Hi Mostafa, yep, these are not GNU Radio core visualizations, but come with gr-baz. You might be using a GNU Radio 3.6-compatible version of gr-baz instead of one that works with GR 3.7. Make sure to install the master branch of github.com/balint256/gr-baz , after removing all remnants of the gr-baz version that you have.
My hint regarding the eye diagram was just to build an eye diagram like it's in the books [1]: An oscilloscope that is triggered on the symbol rate.
