@mdigiorgio reports that a trappy.FTrace object created with an events= parameter that aliases one that already exists confuse the plotter and doesn't let you plot what you want. For example:

trace = trappy.FTrace(trace_file, events=["thermal_temperature"])
trappy.LinePlot(trace, signals=["thermal_temperature:temp"]).view()

RuntimeError: No plots for the given constraints

However, trappy.thermal_trace.data_frame["temp"].plot() works. The aliased thermal_temperature confuses the plotter.
