If you click on your map, you'll see a pop-up window with all of the information contained in the attribute table.
As you'll see, the pop-up doesn't look very nice. The names won't make much sense to the map viewer, and the viewer probably wouldn't be interested in some of the information, like the ntacode
.
Let's configure our pop-up so that it looks better and provides more useful information.
- In the map's Layers Panel, hover over where it has the name of the shapefile
NYCntaPerBlack
, and you will see some options appear below it—"Show Legend", "Show Table", "Change Style", and "More Options." - Select More Options by clicking the three dots below the name of the map layer.
- Select Configure Pop-up. The Layers Panel will turn into a panel for configuring the pop-up.
Let's explore the options that we have for the pop-up.
- The first thing you'll see is a checkbox for turning on and off the pop-up. We're going to leave ours on.
- In the Pop-up Title, you can enter a name that will be displayed at the top of every pop-up box. You can type in something. Or you can have one of the attributes displayed. Let's have the neighborhood name displayed in the pop-up title. To do this, click the plus sign to the right of the text box and select
ntaname
. Next tontaname
, write "(Black%). Now the title will show the name of the neighborhood and the text "(Black%)". - In the Display, select the drop-down to see the list of options. The options for what you can display in the pop-up are "A list of attributes", "A description from one field", "A custom attribute display", and "no attribute information". We are going to select A description from one field since we are only interested in showing the value for Percent Black. Then in the next drop-down select
BINHP
. - Then click OK to save our changes.
Now when you click on the map you should see a popup with just the name of the neighborhood plus the text "(Black%)" and then in the box you will see the value for Percent Black.
