Figure 8-71: Searching Amazon’s website

Figure 8-72: URL action dialog box

To enable Tableau to automatically change the search sent to Amazon based on selections you make in your dashboard, you must replace the static search keywords contained in the URL string with fields inserted by Tableau. Figure 8-73 shows you what parts of the string to replace.

Figure 8-73: Inserting URL variables

The top half of Figure 8-73 shows the original search string. The bottom shows the string with the Tableau fields inserted using the insert arrow to place the desired fields. Use the Test Link button to verify the search is working correctly.

Go back to the bullet graph in the Main Dashboard and execute the menu action with a different product. Hovering your mouse pointer over the Market Analysis text table should trigger another search of the website, and the products displayed should reflect the new search fields inserted by the URL action. Figure 8-74 shows Dashboard 2 after selecting the Expresso, Café Mocha bar in the bullet graph while in the Main Dashboard.

Using embedded Web Page objects with URL actions provides a method for combining your data with information from the Web without having to be a programming expert. URL actions can be used in many different ways. I hope you can see the potential for enhancing your dashboards with information from the Internet. Next, you will add an action to provide a way for the user to navigate back to the Main Dashboard from Dashboard 2.
