Support for multi datafeeds error?

[jjphung]

Hello all,

This looks like an amazing library! After trying out the "Quickstart" Guide, I run into the following error + stacktrace:

  File "/opt/conda/lib/python3.9/site-packages/backtrader/cerebro.py", line 996, in plot
    plotter.show()
  File "/opt/conda/lib/python3.9/site-packages/backtrader_plotting/bokeh/bokeh.py", line 534, in show
    model = self.generate_model(idx)
  File "/opt/conda/lib/python3.9/site-packages/backtrader_plotting/bokeh/bokeh.py", line 364, in generate_model
    panel_analyzer = self.get_analyzer_panel(analyzers)
  File "/opt/conda/lib/python3.9/site-packages/backtrader_plotting/bokeh/bokeh.py", line 389, in get_analyzer_panel
    table_header, elements = self._tablegen.get_analyzers_tables(analyzer)
  File "/opt/conda/lib/python3.9/site-packages/backtrader_plotting/bokeh/datatable.py", line 62, in get_analyzers_tables
    title, table_columns_list = TableGenerator._get_analysis_table_generic(analyzer)
  File "/opt/conda/lib/python3.9/site-packages/backtrader_plotting/bokeh/datatable.py", line 39, in _get_analysis_table_generic
    add_to_table(analyzer.get_analysis())
  File "/opt/conda/lib/python3.9/site-packages/backtrader_plotting/bokeh/datatable.py", line 31, in add_to_table
    for ak, av in item.items():
AttributeError: 'list' object has no attribute 'items'

Is there support for multi datafeeds? For multi-datafeeds I am implementing it similar to: https://backtest-rookies.com/2017/08/22/backtrader-multiple-data-feeds-indicators/.

To reproduce this error, simply use the Strategy provided in the link above.
