Suggestion: Vertical Legends on Horizontal slider

[ihabadly]

Thanks for the great efforts, one suggestion, in case it is not already implemented, is it possible to have vertical legends on horizontal slider?

Thanks

Sorry for the delay. Indeed, this is not implemented at the moment and it would be quite complex to add.

I won't implement it but I'm still open to merge a pull request bringing this feature.
