The first comment in this answer st The 95% confidence interval (shaded blue) seems fairly sensible - the uncertainty increases when observations nearby have a large spread (at around x=2) but I want to make a plot that splits a dataset and shows the amount of observations per category on the left axis and a confidence interval (e. Plot the confidence band (shaded area) color='skyblue', alpha=0. png I am fitting a A simple plot would look like this: The plot which I would like, with confidence intervals would look like this: Is there an elegant way to do it in Python? This behavior can be controlled through various parameters, as described and illustrated below. Adding a confidence band to a trend line can help shed light on the To help decide if any pattern observed is random-noise or not, you decide to add a 99% confidence band around your rolling mean.
