Tip 2: Unlock 14 additional map styles by integrating Mapbox ► Related video: A Formatting Trick for Tableau Scatter Plots and Maps Here’s how the same map looks with closed diamonds for the interior marks and open diamonds for the borders: Lastly, the dual-axis formatting effect works with any mark type. If you are simply looking to increase the size of the borders, you can change the mark type for the borders to Circle (which is the same as the interior marks), remove the dimension on the Color Marks Card for the borders, make both marks opaque, and increase the size of the borders as much as you would like. There are several design possibilities now that the marks and their borders can be edited independently of each other.įirst, you can make the size of the borders larger than the size of the interior marks, creating a layered, ‘target’ effect. Here’s how my final view looks after changing the opacity of the interior circles to 50%: To change the order of the marks, simply drag one of the Latitude pills in front of the other on the Rows Shelf. When you convert a map to dual-axis, the default behavior is for the second map to lay on top of the original map in the first row. Next I will combine the maps into a dual-axis map by clicking on the second pill on the Rows Shelf and selecting “Dual Axis”. That means I can leave the first map as is but change the mark type for the second row to Shape, choose open circles for the shape, and remove the ranking labels. Now that there are two measures on the Rows Shelf, they each have their own Marks Shelf that can be edited independently of each other. To begin, I’ll place the Latitude measure on the Rows Shelf a second time. This is a trick I picked up from my friend, Matt Hoover, who is a data scientist at Flywheel. To make matters worse, halos disappear completely once the opacity is reduced to less than 90%.Īll of these limitations can be overcome by leveraging a dual-axis to format the marks. you can’t reduce the transparency of marks without reducing the transparency of effects). Also, a tip that I always recommend is to reduce the saturation of marks by reducing the opacity to 85%, but borders and halos inherit the same transparency of the marks themselves (i.e. you can’t have a different color for each mark). Most notably, you can only choose one color at a time for both borders and halos (i.e.

While these effects can provide a subtle professional polish to the marks, they have several limitations. One of the effects that I like to add to symbol maps are borders and/or halos around the marks both can be found by clicking on the Color Marks Card.

Tips include a formatting trick, instructions for how to unlock additional map styles, and how to create a dual-axis map using a combination of generated and custom coordinates. This post will use a map of my top 10 favorite barbecue restaurants to share three ways to take your Tableau maps to the next level. This unlocks even more applications including the ability to map anything – even if it’s not related to geography. What’s more, Tableau maps are technically scatter plots with points at the combination of each latitude-longitude pair and an image of a map in the background. This makes it so that simply double-clicking on a dimension that Tableau recognizes as geographic will create a map on the view. They are easy to create because Tableau comes prepackaged with thousands of geographic coordinates all over the world. They are effective because they help us decode latitude and longitude combinations almost instantly, allowing us to see patterns between geographic locations that may otherwise be challenging to discover. Maps are one of the most effective chart types in Tableau and are also among the easiest chart types to create.
