Share New Research 
Hello,
I am somewhat new to running LEAN locally. When I run the backtest everything appears to go well but the information returned on the .json file for the charting is empty. I have a custom chart with some indicators and the series attached to the chart is empty. On QC cloud environment the charting and indicators work just fine. Can someone help me to understand what is happening or what should I expect from the .json file? Thanks in advance.
This is how I am creating the char and series:
# Function called in the Initialize method
chart = Chart("MyIndicators")
self.AddChart(chart)
self.mycandles = Series('SPY',SeriesType.Candle,0,'$')
chart.AddSeries(self.mycandles)
self.series_poc = Series('POC',SeriesType.Line,0,'$')
chart.AddSeries(self.series_poc )
self.series_vah = Series('VAH',SeriesType.Line,0,'$')
chart.AddSeries(self.series_vah)
self.series_val = Series('VAL',SeriesType.Line,0,'$')
chart.AddSeries(self.series_val )
self.series_atr = {}
self.series_atr['atr_high'] = Series('ATR High',SeriesType.Line,0,'$')
self.series_atr['atr_low'] = Series('ATR Low',SeriesType.Line,0,'$')
self.series_atr['levels'] = Series('ATR Levels',SeriesType.Scatter,0,'$')
for s in self.series_atr.values():
chart.AddSeries(s)
self.series_volume = Series('Volume',SeriesType.Bar,1,'')
chart.AddSeries(self.series_volume )

Hi Andres tello,
Do you have the backtest data on your local machine? If the data is not in place, the charts won't be populated.
Best,

i dont think quantconnect displays charts locally. I think they just output to the backtest json files. Then you can load/chart them in research. I'll open source some examples within the next couple week. I would like to make an angular dashboard to chart the stock history and compare backtest entries/exists but am running into blocks with that, but that would be way better than jupyter notebooks if i can do it.

Note you can't chart in research using QC's chart functions, i meant using the libraries here:

Also note there isn't a way I've found to locally display the QC backtest page in the online version, though that will probably be included in the custom IDE they are making.
