Legend for Displaying DA>50% using Ladybug

Hello :grinning:
I am a rather new user of ladybug and the daylight components.
I have successfully created a proper script for visualising data, referring to Daylight Autonomy.
Here I am right now showing a standard mesh from blue to red. My question is, how do I change the legend, so I only display one line? A line representing the area of which one side is under 50% DA and the other is over 50% DA.

Hi - you’ve probably noticed that without a Grasshopper definition and/or a lot more details, you won’t get any useful answers - if any answers at all.

Also, if your question is about Ladybug components, please visit the https://discourse.ladybug.tools/ forum.
