Thanks for the datasources; they confirmed what I was doing!
And then, just to finalize this, as my previous script was indeed a very crude and hastily comprised. I had to abandon all Asserts (including softAsserts), so a better generalized version below having two datapoints: FailedStep and GeneralSuccess (not really needed, but just for clarity). Two graphs as well having the same ones where FailedStep has vertical label description as "ZeroIsGood" and GeneralSuccess has "OneIsGood". Of course alert thresholds set respectively. This quite probably fits my needs nicely when cloning and amending to multiple different tests. (One development step would still be to get rid of the "--no-sandbox" as it is a security risk to run chromedriver as root.)
