But this has two huge disadvantages: In our case, we can declare the style as bars which essentially graphs the confidence intervals into a scaled line bar to depict the confidence intervals within each year of our data points. Sorry for the late reply, I did not use plotly for quite a while. With px.line, each data point is represented as a vertex (which location is given by the x and y columns) of a polyline mark in 2D space.
