Polishing Layers

[teunbrand]

This issue is more of a tracker so we can see the progress in what layers remain to be implemented versus what we already have.
Mostly, they'd need polish: add a few parameters we care about, and ensure the layers are documented with examples so we know that they are working.

• abline (Lines and Segments #159)
  • hline (Lines and Segments #159)
  • vline (Lines and Segments #159)
• area (Polish area and ribbon layers #97)
• arrow probably a claudism
• bar
• boxplot (Boxplots #88)
• density (Density layer #110)
  • violin (Density layer #110)
  • ridgeline
• errorbar (Lines and Segments #159)
• histogram
• label
• text (Text layer #155)
• line
• path (Polish polygon / path layers #103)
• segment (Lines and Segments #159)
• point
• polygon (Polish polygon / path layers #103)
• ribbon (Polish area and ribbon layers #97)
• smooth
  • linear model
  • local smooth
• rect (Rectangles #168)
