Strategy for handling non-plottable values in Plots

[akhenry]

Is your feature request related to a problem? Please describe. Some discussion is needed to establish a consistent strategy for dealing with values that cannot be plotted. Non-plottable values include NaN, Number.POSITIVE_INFINITY, Number.NEGATIVE_INFINITY, undefined, and values that break a Float32Array (Above 3.4+38, Below -3.4+38). We should address questions such as

• Should we give some visual indication on the plot itself that the is a value for a given timestamp, but it is not plottable?
• Should we interpolate between valid point, ignoring any non-plottable values, or should we leave gaps for any non-plottable values?

This relates to

• https://github.com/nasa/openmct/issues/2531
• https://github.com/nasa/openmct/pull/7138

@jvigliotta Can you check with @charlesh88 and close this if we aren't doing anything here? Thanks!

@shefalijoshi I think this should stay open for now, we have some further work to do related to this.
