Hello, I have a figure with three subplots, where the third is overlay of the first and second. First subplot is created by go.Image, second by go.Heatmap. For some reason they have switched y axis, but the overlay is correct. Does go.Image or go.Heatmap invert the figure in y? How is it possible …

Thank you, I ended up with fig.update_yaxes(autorange="reversed") Which does the trick. I thought that fig = fig.update_layout(yaxis=dict(autorange="reversed")) does the same thing, but apparently my syntax was wrong in this line somehow (Plotly still confuses me a bit).

Inverted image in go.Image vs go.Heatmap?

Yes, go.Heatmap() inverts the y-axis. Instead of go.Heatmap() you could use px.imshow() which has the parameter origin which alters this behaviour.

I don’t know
