After you create a map in Tableau, you can change your map's display and data layers as well as other characteristics.
- After you create a map in Tableau, you can change the layers that appear on the map. In this movie, I will use the 1202 layers sample workbook, and you can find that in the chapter twelve folder of your exercise files collection. This map shows sales data for a number of states for the company that we're using as our scenario. There are sales for Alaska, but to make the map larger, I have filtered those out, so that we can focus on just the mainland US.
This map has a light gray background, and you can see that we have bodies of water in white and also significant forest coverage in a slightly darker green gray. If I want to change that map's appearance, as well as add potential data layers, I can go to the Map menu, so I'll click Map and then click Map Layers. Doing so displays the Map Layers panel in the navigation area. If I want to change the background style, in this case it is set on Light, I can click the style controls down arrow, and I have Normal, Light, and Dark.
So I'll show you what Normal looks like by clicking that. And it's probably closer to what you're used to seeing. Basically it's just darker colors of everything that we saw just now. And then I'll click the style down arrow again and click Dark, and that's with black where there was white and then a medium gray to indicate water. I'll go back to Normal, which shows a little bit more contrast. So I will click Normal from the style control. There we go. You can add or remove different items.
So for example, if I wanted to remove the land cover, which in this case is mostly forest, I would clear the Land Cover check box, and now we don't have our forests anymore. I'll click to bring it back. I can also get rid of country and region names, so I'll clear that check box. And if we scroll down under Map Layers, we'll see that there are other items. So for example, we can get rid of state and province names if I clear that check box. Then you're on your own to remember that this is Iowa.
I'll bring it back. And scrolling down you can see that there are other items, such as area code boundaries, area code labels, and so on, but we don't need those for this lesson. You can also show different data layers, and you see that here under Data Layer. We currently don't have anything set, but if I were to click the layer controls down arrow, we would see a lot. So here we have Population, Population Growth Percentage Estimated for 2018 Through 2023, Median Age, and Population by Race, Occupation, Income, and so on.
Let's say that I want to display the data related to population. So I'll go up under US Population and click Population, and when I do, Tableau displays information related to population. So you can see that for Montana, North Dakota, South Dakota, and Wyoming, population for all those states is between 587,000 and 1.3 million, which you see here. The slightly darker states have more people, and the darker blue have between 8.9 million and 39.7 million.
You can change the color scheme. So if you go over to Data Layer, you'll see that there is population by state. You can also change that. You can do it by county, zip code, block group. And then if you want to use a different color scheme, you can click Using, and go from blue-green sequential, which is the one that I prefer, to perhaps gray sequential, where the colors get darker as the population gets higher. If you want to remove that data layer, you can click Layer and then scroll up and the very first item all the way at the top is No Data Layer, and that removes it.
So as you can see, you have access to a lot of different information. You have your own data that you've captured from your company, as well as publicly available data that you can use to enhance your maps.
