Inconsistency with marker transparency

Issues

Hi Team,

While playing with the opacity of the box plot, I realized a few inconsistencies between the scatterplot and the boxplot.

  1. In the box plot, it’s called opacity, in the scatter plot alpha.
  2. High opacity values (up to 255) are making the markers transparent, but instead it should be the other way around
  3. Low alpha values (down to 1) are making the markers transparent, but instead it should be the other way around
  4. Opacity goes down to 0, alpha only down to 1.

My suggestion: Can we just call it transparency for all viewers, with a range from 0-100 (%), where 0 is not transparent at all, and 100 is fully transparent?
I think that would be easier to be used by non-technical folks (the ones who don’t think hexadecimal :wink: ) and would be more consistent.

Hi Nico,

This is a good point.

Instead of several similar properties responsible for transparency, we made a unified one - opacity.
This is the level of color visibility in percent (must be in range 0…100). For viewers, this property will be called markerOpacity.

markerOpacity = 0 means that marker is fully transparent (invisible).
markerOpacity = 100 means that marker is fully opaque (visually solid).
