Expected behavior

On latest v3 I used options.backgroundColor: [array of strings of hex colors]. On v4 it doesn't seem to have any effect, and I can't find any migration about that.

Edit: it seems it must be inside datasets array, where is this mentioned in the migration from v3 to v4?!

Current behavior

Default light blue colors are shown.
