chart.js barchart without set fill color

Question

This is my first time using Chart.js and I want to create bar chart with multiple series. Based on documentation we have to specify fillColor for each dataset. Is that possible to create multiple chart without set fillColor (like barchart in excel).

Accepted Answer

fillColor uses rgba. a = alpha. you can set alpha value to 0. such as

```
fillColor: "rgba(220,220,220,0)"
```

this should give it a transparent fill color and still display the border colors assuming you have them not transparent.
