# --description--
Instead of simply using the year(`d.year`) for the x-coordinate, you need to pass each year to the `xScale` so it can set the appropriate coordinate based on your scale.
In the "d function" you created, return `xScale(d.year)` instead of `d.year`.
# --hints--
test-text
```js
assert(/\.x\s*\(d\s*=>\s*xScale\s*\(\s*d\.year\s*\)\s*\)/g.test(code));
