| This is one example https://github.com/grst/jukitty

|

| I use matplotlib a lot but I keep googling the same things again
| and again, which is my subjective indicator that something in the
| design is wrong. How to set log scales again? Do I apply this
| method to the figure or axis object? Setting a different backend
| (like agg) after pyplot was importet? Also, nested kwargs make it
| impossible for my IDE to give meaningful hints on parameters, not
| even talking about typed interfaces so far. Global state!
|
| I mean, this library solves a truly complex problem and yes, I
| get things done but none of the hours working with it was close
| to be pleasant.
|
| I wish some day someone is brave enough to enter new lands,
| leaving this matlab style of thinking behind.

| Very cool library!
|
| As alternatives I might recommend hipsterplot (the name) or
| uniplot (very similar but lighter, I'm the author).
