with plt.style.context('capon'):
    markets.pivot_table(index='timestamp', columns='symbol', values='relative_price').plot()

Visualization with altair

import altair as alt


with alt.themes.enable('capon'):
    display(
        alt.Chart(markets)
        .mark_line(interpolate="monotone")
        .encode(
            x=alt.X("timestamp", title=None, axis=alt.Axis(format="%b %y")),
            y=alt.Y("relative_price", title="Relative Price", axis=alt.Axis(format="+%")),
            color="symbol",
            tooltip=["timestamp", "symbol", alt.Tooltip("relative_price", format="+.2%")],
        )
        .properties(
            title={
                "text": f"Market Indexes Change",
                "subtitle": f"Relative to {markets['timestamp'].dt.date.min()}",
            },
