# --description--
Go back to where you defined your `xAis` variable and chain the `tickFormat` function to it. Pass it `d3.format('')`. This will remove the commas in the year labels of the x-axis.
# --hints--
test-text
```js
const ticks = $('.tick > text');
assert(ticks[6].innerHTML === '2012' && ticks[14].innerHTML === '2020');
```
