How to properly plot a line over bars?

This one used to work fine, but somehow it stopped working (I must have changed something mistakenly but I can't find the issue).

I'm plotting a set of 3 bars per date, plus a line that shows the accumulated value of one of them. But only one or another (either the bars or the line) is properly being plotted. If I left the code for the bars last, only the bars are plotted. If I left the code for the line last, only the line is plotted.

fig, ax = plt.subplots(figsize = (15,8))    df.groupby("date")["result"].sum().cumsum().plot(      ax=ax,      marker='D',      lw=2,      color="purple")    df.groupby("date")[selected_columns].sum().plot(      ax=ax,      kind="bar",      color=["blue", "red", "gold"])    ax.legend(["LINE",  "X", "Y", "Z"])  

Appreciate the help!
