I'm using matplotlib to display a stock's price movements over time. I want to focus on the last 90 days and then predict the next 14 days. I have the last 90 days of data and my predictions, but I want to graph my predictions in a different color, so it's clear they're different.

How would I do this?

If I just add a second `plot()` call to my code, the predictions will start from the same point as my 90 days of data and be overlaid, which isn't what I want.

Right now I'm doing this:

```
df[-90:]["price"].plot()
plt.show()

```

Thanks!
