Notice the San Diego Convention Center Building is a darker shade of gray than the other buildings.
What: We wanted to draw attention to the San Diego Convention Center. Why: Because people with this map would start there as they entered the Gaslamp District to find lunch. How: We chose to show all other buildings with 20% gray, and used 40% gray on the convention center. This gray was one of the last things we verified in order to be sure it would not compete for attention with the restaurant point symbols.
Using unique values symbology to accomplish the effect of one building having a different color.
First notice that unique values symbology method was used; next, to set up the symbology as we did, follow these instructions:
- Set the Value Field to be the name field or whichever field contains value that will uniquely identify the feature you want to highlight.
- Before you click the Add All Values button at the bottom left of the Symbology tab consider whether there a potentially hundreds or thousands of unique values in the data you’re using. If not, go ahead and click the Add All Values button. If there a lot of unique values, click the Add Values button, which will allow you to select from that list or type the value you want.
- Make sure the <All other values> option is checked on.
- Click the OK button and then change your symbols from the table of contents to be the desired symbols or colors.
