Tableau Maps are convenient to visualize the geographical data. In this article, we will show you how to Create regular Maps in Tableau with an example. For this Tableau Maps demo, we are going to use World Indicators data sources that come with the desktop.
Create Maps in Tableau
There are multiple ways to create Maps in Tableau. And in this article, we will explain all of them.
Drag and drop any Geographic field to Row or Column shelf, and selecting the icon in Show Me window will automatically create a Map in Tableau. In this example, we will drag the Country dimension to Columns Shelf
Next, Drag and Drop Total Population from Tableau Measures Region to Rows Shelf. Since it is a Measure value, the Total Population will aggregate to default Sum.
Let me change that Bar Chart into a World. To do so, Please expand the Show Me window and select the marked option from it
Once you choose this from Show Me window, Tableau Map will be displayed. From the below-shown screenshot, you can see Row and column Shelf’s filled with generated Latitude and Longitudes. And, Country added to Detail Card, and Total Population will add to Columns Card.
You can highlight any country to see that Country population
Double-click on any Geographic filed such as Postcode, City, State, or Country will automatically create a Tableau Map. In this example, we will double-click on the Country dimension. From the below screenshot, you can see, the desktop has created a Symbol for you. Here, it added the Latitude to Row shelf, Longitude to Column shelf, and Country Name to Details Card in Marks Shelf.
To convert the Symbols, either you can click on the marked one from the Show Me window or you can change the Marks type from Automatic to Map
Either way, it will generate the below for you
Let us add Population Total to Colors card in Marks Shelf. It will add color to every country based on their Population.
Create Maps in Tableau – Third Approach
Drag and drop any Geographic field on the Details card will automatically create a Tableau Map. In this example, we will drag the Country Name dimension to Details card present in Marks Shelf
Now you can see the auto-generated symbol. Use either of the approaches mentioned above to convert the Symbol to Map in Tableau.
Add Data labels to Maps in Tableau
To add data labels to Tableau Maps, Please click on the Show Mark Labels button in the Toolbar. Though it looks odd, you get the idea of adding data labels.
Until now, you saw the Tableau Maps with the default colors, but you have an option to change the default colors. To do so, click the drop-down menu beside the SUM(Population Total) color legend or right-click on the Color bar. Both of them will open the below-shown context menu. From that, please select the Edit Colors… option
Once you choose the Edit Colors… option, the following window will open. Click the drop-down arrow under the Palette and select the color as per your specification. For now, we are choosing Gold-Purple Diverging. Remember, by clicking the Advanced button, and you can specify the Start Point, End Point, and Center as well.
Now you can see it with Gold-Purple Diverging color schema.
