How adjust spaces between cluster bars in AmCharts JS

I used to use AmCharts flash version and in the flash version I can easily create cluster column/bar charts like the image below. As you can see the clustered bars have no space apart. I am having trouble doing the same with the JS version of AmChart. enter image description here

In the JS version here is what it looks like.

enter image description here

I tried playing around with the configuration but still cannot find a way to eliminate the space between the clustered bars.

Below is my code.

<!DOCTYPE html>
<html>
<head>
<title>chart created with amCharts | amCharts</title>
<meta name="description" content="chart created using amCharts live editor" />

<!-- amCharts javascript sources -->
<script type="text/javascript" src="https://www.amcharts.com/lib/3/amcharts.js"></script>
<script type="text/javascript" src="https://www.amcharts.com/lib/3/serial.js"></script>


<!-- amCharts javascript code -->

You need to set "columnSpacing":0 for the bars and they'll touch.

right at the top of your code, line 16 after "type": "serial", add a line of:

"columnSpacing": 0,

Here's a JSFiddle https://jsfiddle.net/1w3tbvyv/
