Observations with string/boolean Values display as blank in Charts and fhir-card

[Royal2000H]

Just set up Fasten and playing around with it with real data.

It appears the non-numeric results just show as

"Result: " (just blank)

If I go into the observation and then debug, it does show results such as:
"valueString": "NONREACTIVE" or "valueString": "NEGATIVE" or "valueString": "NOT DETECTED"

Ah thanks for calling this out. I had seen it previously but it slipped my mind.

I had been focused on graphing numerical Observations, but boolean (and string) values require some additional work to display and compare correctly.

From my discussion with @jean-the-coder on Discord:

They're all kind of related to the fact that Fasten only handles numerical values for lab results at the moment, because I display everything on a graph. Anything that's not a number is ignored by chartjs I think.

A simple workaround for now might just be to display a table of values if any of the lab results is a string.
