python scripts/plot_dataframe.py -p BTC/ETH
```
The `-p` pair argument, can be used to specify what
pair you would like to plot.
The `-p` pairs argument, can be used to specify
pairs you would like to plot.
**Advanced use**
To plot multiple pairs, separate them with a comma:
```
python scripts/plot_dataframe.py -p BTC/ETH,XRP/ETH
```
To plot the current live price use the `--live` flag:
```
python scripts/plot_dataframe.py -p BTC/ETH --live
