Deprecated function matplotlib.plt.hold for use case "Purkinje cell simulation and validation" #496

Closed alex4200 closed 4 years ago

alex4200 commented 4 years ago

Expected behavior

Use case "Simulation and validation of a mouse Purkinje cell multicompartmental model" from the Single Cell Modelling runs without error.

Actual Behavior (please include screenshot if possible)

In that use case there can be the following error:

AttributeError: Module 'matplotlib.pyplot' has no attribute 'hold'.

Steps to reproduce the problem

  1. Install matplotlib version >3 (e.g. 3.1.2)
  2. Restart the kernel
  3. Run the notebook

The reason is that the 'hold' attribute for 'matplotlib.pyplot' has been removed for matplotlib version >=3. It looks like you just can remove that line in the cell where you define the function 'trace_features'. The notebook seems to run just fine (and still creates the same plots as before).

Hi.

I have changed it to plt.close() to prevent multiple images to fuse together. This command causes a warning that is irritating but innocuous.

Thanks, work now
