Add legend for colour scale #12
Comments
Indeed, will do after implementing the proper color scale (#2). |
Update: There's now a basic legend, comments welcome! |
Nice, but the unit is not indicated. 😄 |
Indeed! @amyjsdavis, what unit should I show? I understand 0 means "no risk at all" and 100 means 100% certainty, would it be better for end-users if we multiply the value by 100 and present them as percent? @SoVDH, maybe you also have an opinion on this? |
@niconoe : yes you are interpreting risk correctly, although in reality there are rarely places that are 0 or 100% risk. Hmm, the convention is show the scale on 0-1, or using the lowest and highest risk as the scale bounds (ie. .005 and .995), but perhaps using percents is more intuitive. I will default to the wisdom of @SoVDH. |
I would suggest showing a range from (0-no risk) to (1 high-risk) for risk maps and (0-low uncertainty) to (1-high uncertainty) for uncertainty maps. Percentage are perceived and interpreted differently from a user to another. Risk communication literature suggests to avoid the use of percentage because if refers to relative risks. |
@SoVDH : that makes sense and is fine by me! |
Implemented |
It is unclear what those colours represent. A legend should be added, with a unit and values.
