# --description--
Set the `y` values for `tumblrLine` using a "d function" again. Use your `yScale` and `d.followers.tumblr` to calculcate their values just like you did for the Twitter line.
The x values for each line will be the same, but the y values will use the data from the different platforms.

```js
assert(
/\.y\s*\(\s*d\s*=>\s*yScale\s*\(\s*d\.followers.tumblr\s*\)\s*\)/g.test(code)
);
