Plots that originally utilized the Python Plotly plotting package are now using Matplotlib. As a result, all plots in this repository utilize Matplotlib. This removes the dependency on chrome by the kaleido module in Plotly. The kaleido/chrome dependency required run-time downloading of chrome and also broke existing functionality.

In the METplotpy-3.1.0-beta2 release, METplotpy switched from development with Python 3.10.4 to
43

development with Python 3.12. View the requirements.txt/nco_requirements.txt file at the top

In June 2025, Plotly made significant updates to the kaleido package with the 1.0.0
49
-
release by removing Google Chrome code. Now, users will need to have Google Chrome
50
-
installed in directories specified in this Plotly documentation (based on operating
51
-
system):
52
-
https://plotly.com/python/static-image-export/
53

54
-
The METplotpy code downloads Chrome at runtime by invoking the kaleido.get_chrome_sync()
55
-
method call.
56
-
57
-
If users do not wish to have Chrome downloaded at run time and already have Chrome installed
58
-
in one of the expected locations (specified in the Plotly link above), then the PRE_LOAD_CHROME environment variable
59
-
will need to be set to 'True' (case insensitive string).
