Your code so far

    df_bar = df_clean
    df_bar = df_bar.reset_index()
    df_bar["year"] = df_bar["date"].dt.year
    df_bar["month"] = df_bar["date"].dt.month

    df_bar_avg = df_bar.groupby(['year', 'month']).mean()
    df_bar_avg = df_bar_avg.unstack()

    months = ['January', 'February', 'March', 'April' , 'May' , 'June', 'July', 'August', 'September', 'October', 'November', 'December']

    fig = df_bar_avg.plot(kind ="bar", figsize=(15,5)).figure
    plt.xlabel("Years")
    plt.ylabel("Average Page Views")
    plt.legend(labels=months)



    # Save image and return fig (don't change this part)
    fig.savefig('bar_plot.png')
    return fig

Oh I figured it out. My unstacked df_bar_avg dataframe had index as a column as well and the plot was charting out the mean() of the index numbers. I had to just drop that column and it worked!
