Test `salinity_ferry_track` Module¶

Render figure objects produced by the nowcast.figures.comparison.salinity_ferry_track module. Provides data for visual testing to confirm that refactoring has not adversely changed figure for web page.

Set-up and function call replicates as nearly as possible what is done in the nowcast.workers.make_plots worker.

NOTE

The next cell mounts the /results filesystem on skookum and the /ocean filesystem locally. It is intended for use if when this notebook is run on a laptop or other non-Waterhole machine that has sshfs installed and mount points for /results and /ocean available in its root filesystem.

Don't execute the cell if that doesn't describe your situation.

!sshfs skookum:/results /results !sshfs skookum:/ocean /ocean
