    A histogram and a density plot can have very different y-axes. Most likely, that simple fact is behind your issue. Plot both separately and compare the y-axes. – Roland Nov 21 '22 at 14:25
  • when iu try to plot them in different graphs, i receive an error: needed finite values in 'ylim', but i cannot find how to solve it – Javier P Nov 21 '22 at 14:41

    [This post](https://stackoverflow.com/questions/19103582/overlay-a-t-distribution-to-my-histogram-using-r) shows a base R example and [this one](https://stackoverflow.com/questions/5688082/overlay-histogram-with-density-curve) is a ggplot solution – DaveArmstrong Nov 21 '22 at 14:52
  • It's easier to help you if you include a simple [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input and desired output that can be used to test and verify possible solutions.

  • Just add `freq=FALSE` to the `hist` instruction. – Rui Barradas Nov 21 '22 at 15:07
