Draw go.Bar over filled go.Scatter (can't get Bar to plot on top of Scatter)

Heya,

I am trying to plot a basic bar histogram. To make the plot visually more appealing, I’d like to add in the background a semi-transparent filled scatter of the same data.

The code:

    def make_figure(self):
        """Draws histogram."""
        fig = go.Figure()
        fig.add_trace(
            go.Scatter(
                x=list(self.data.index),
                y=list(self.data["num_keys"]),
                mode="lines",
                line=dict(width=1, color="black", shape="spline"),
                fillcolor="rgba(1,1,1,0.5)",
                fill="tozeroy",
            )
        )
        fig.add_trace(
            go.Bar(
                x=list(self.data.index),
                y=list(self.data["num_keys"]),
                marker=dict(color="white", line=dict(color="black", width=1)),
            )
        )
        return fig

The problem is that the scatter ends up in the foreground. See output:

To solve this problem, I’ve tried several ways to instantiate the figure (eg fig = go.Figure(data=[scatter, bar], etc), but the scatter always ends up on top.

Is there a way to get the bars to plot on top of the scatter?

Thanks!
