Question: I made multiple observations of my plants (one per week) and divided the plants into 2 groups (with and without treatment). My data structure looks like this:

```
Treatment   Leaf Area 1 Leaf Area 2 Leaf Area 3 Leaf Area 4 Leaf Area 5
none        2.411545455 13.02745987         
yes         1.199545455 0.412511147         
none        2.448363636 28.56727482 51.49511341 49.38664803 15.63761378
yes         2.797454545 23.49791914 31.97397924 39.60835617 8.544331072

```

I want to create a line chart similar to the following. Can anyone please help me? I don't really know where to start looking.

Answer: 
This is a reported bug for ansible. The issue can be seen [here](https://github.com/ansible/ansible/issues/20702). Although there is a pull request merged in the mainline code for this (see [here](https://github.com/ansible/ansible/pull/20717)), if the issue is not fixed for you, would be good to re-open it. Also, try the fixed provided in the `Common issues` section [here](https://github.com/networktocode/ntc-ansible).
`unset ANSIBLE_LIBRARY`

`ANSIBLE_LIBRARY` was set to a bad path which was causing this error.
