datamon.js: Plot classes overwrite the `tag` key in data passed into plotly plots
One example of this is in serve.py
, where the JSON returned by certain urls is in the form:
{'x': [...], 'y': [...], 'name': name_of_plot}
This 'name' option should populate the legend in a plot where we're plotting multiple timeseries, but that gets overwritten in the plot class, causing the traces in the plot to have the generic name 'trace1', ..., 'traceN'.
