python - How to remove gaps between bars in Matplotlib bar chart

Question

I'm making a bar chart in Matplotlib with a call like this:

xs.bar(bar_lefts, bar_heights, facecolor='black', edgecolor='black')

I get a barchart that looks like this:

What I'd like is one with no white gap between consecutive bars, e.g. more like this:

Is there a way to achieve this in Matplotlib using the bar() function?

Answer 1

Add width=1.0 as a keyword argument to bar(). E.g.

xs.bar(bar_lefts, bar_heights, width=1.0, facecolor='black', edgecolor='black').

This will fill the bars gaps vertically.
