Question: Is it possible to download raw data that qf calculates

Hi,
I would like to know if it's possible to download raw data that are used to plot. I've my data and want to add RSI to them doing following:

```
qf = cf.QuantFig(df = ge.loc["2019":])
qf.add_rsi(periods = 20, rsi_upper = 70, rsi_lower = 30)
qf.iplot(title = "GE", name = "GE")
```

The output is awesome, but I would like to learn RSI values on particular days.

Please advise.
