Plotlyjs fill for negative y values

plotly.js
1

Hello,

I have a plot where all of the y values are negative. I’d like the fill under the trace to the bottom of the plot (like how shapes like you draw to the bottom of the plot) but it looks like there is only fill to zero (tozeroy, tozerox, so on).

I’m basically looking for something that is the opposite of the plot below. Instead of fill to zero I’d like to fill to some other negative value or to the bottom of the plot. Is there a way to do this?

I was able to do this using two traces. Not sure if there is a better way but I thought I’d post what I ended up doing in case someone else runs into this.
