I am using chart.js throug chartkick gem.

```
= column_chart [{"name":"A","data":[["2016-07-01",1],["2016-08-01",0],["2016-09-01",0]]},{"name":"B","data":[["2016-07-01",1],["2016-08-01",0],["2016-09-01",0]]}], xtitle: "Date Range", ytitle: "Counts", stacked: true, height: "600px"

```

I am getting following chart:
[![enter image description here](https://i.stack.imgur.com/72yva.png)](https://i.stack.imgur.com/72yva.png)

I don't want any border around stacked blocks. I want to set border to 0. How can I achieve this using chartkick gem?

I tried adding this on page load in application.js.

```
Chart.defaults.global.elements.rectangle.borderwidth = 0;

```

But this is not working.
