15. Formatting the Legend
A map legend is a visual explanation of the symbols used on the map. It typically includes a sample of each symbol (point, line, or polygon), and a short description of what the symbol means. Let’s have a quick look at the legend to make sure that it will be informative for our map viewer.
- In the Map Layers Panel, at the top, you should see three icons—an “i” with a blue circle around it, followed by a paper with blue writing, and then a bulleted list. Click on the icon that looks like a bulleted list; that’s the legend icon.
- I think the legend generally looks okay, but it currently displays the name of the map layer, which can be a little confusing for the viewer, especially the layer
NYCntaPerBlack. Let’s rename the layers so it will be easier for the viewer to understand.
- Go back to the Map Layer panel where you can see the hyperlinked layers. You can do this by clicking the icon that looks like a white sheet of paper with blue writing.
- Then click on the three dots for More Options and select Rename.
- Do this for both layers to rename them something that’s easier to read. I’m going to name mine “BLM Protests (May 28 to June 3, 2020)” and “NYC Neighborhoods by Percent Black.”
