how to plot a line chart with error values in matplotlib?

Question

I have a time series stored in pandas DataFrame with columns low, average, and high. Currently, I plot the average values as a line chart, but I would like to fill the area between low and high values with a color.

I am hoping to create a chart that looks exactly like this

What have you tried? Anything that looks promising but you can't get it to work? — msitt

I think it's something like:

ax.fill_between(df.index, df.upper, df.lower, where= df.upper > df.lower,
facecolor='red', alpha=0.5, interpolate=True)

Where ax is your axis, df is the DataFrame and upper and lower the bounds.
