The -p pair argument, can be used to specify what
|
||||
pair you would like to plot.
|
||||
|
||||
**Advanced use**
|
||||
|
||||
To plot the current live price use the --live flag:
|
||||
```
|
||||
python scripts/plot_dataframe.py -p BTC_ETH --live
|

```
|
||||
|

To plot a timerange (to zoom in):
|
||||
```
|
||||
python scripts/plot_dataframe.py -p BTC_ETH --timerange=100-200
|
||||
```
|
||||
Timerange doesn't work with live data.
