How to decrease spacing between bars in a stacked bar graph?

Question

I am trying to plot a stacked bar graph. However, I am not able to reduce the spacing between bars. I want to keep the bars narrow but no space between the bars or very less space.

I am using the following code:

 #!/usr/bin/env python3
# -*- coding: utf-8 -*-

Answer 1

The function bar()'s params are same as follows:

bar(left, height, width=0.8, bottom=None, hold=None, data=None, **kwargs)

What you should see is left parameter. That represents the starting point of each bar.

In your code

range(len(MA1D))
# this would be [0,1,2]

So in order to decrease width, you just need to make something like below

[0.3,0.5,0.7]

In this case you should be careful on the parameter width. As you can see width's default value is 0.8

I believe you can adjust it yourself.
