Sending a blueprint withan empty barchart crashes the viewer about rerun HOT 8 CLOSED

Things to investigate:

• egui_plots has been updated
• aspects of fallback values have been changed that could cause us to be sending different data to egui_plots in this case.

that's a debug assertion only, fixed it for the time series chart already but didn't realize there it was new

I don't really understand why scalar_axis.component_or_fallback::<Range1D> returns an inverted range though

I suspect this is to blame:

I'll clean this up
