That’s okay – we can fix that. The following is a step by step guide to reshaping your data so you can make the most of it in Tableau. First, make sure there are no blank rows or columns within your data set. That’s usually pretty easy to fix manually but if there’s a systematic problem (like every fifth row is empty) you might prefer to use this nifty tool called Data Wrangler (more on this later) developed by the good people at the Stanford Visualization Group. The data also needs to be in a data table format where each row contains only one piece of data. Normalized Data (you want your data shaped this way): Crosstab Data (you don't want it shaped like this): While crosstabs make sense to people, it makes our software’s head hurt because each row contains three pieces of data -- in this case the company's net income in 2010, 2009 and 2008.
Start by going to Data Wrangler and watching the brief intro video. Creating a Set. There are many ways to create and edit sets in Tableau. To create a set, select marks or headers in the view or control-click a field in the data window. You can also create a set that is based on a filter you've already defined. Regardless of how you create the set, it is either constant or computed. A constant set contains a specified list of members based on one or more dimensions. For example, a constant set might contain the specific names of products that you are keeping an eye on. Constant Sets The members of a constant set are fixed and do not change. Select one or more marks or headers in the view. When finished, click OK. Computed Sets The members of a computed set are dynamic and change when the underlying data changes.
Control-click dimension in the Data window. Set limits work the same as Filter limits. Finding the Top N Within a Category | Tableau Software. Article Note: This article is no longer actively maintained by Tableau. We continue to make it available because the information is still valuable, but some steps may vary due to product changes. The Top tab in the Filter dialog box allows you to define a filter to show the Top N items based on a specific measure.
For example, you can use this type of filter to show the top 5 categories by sales in each region. This type of filter is computed across the entire data source. You can see that the same 5 categories are shown within each region because those are the top 5 selling categories sold across all regions. Instead of computing across the entire data source, you can calculate the Top N within a category by combining fields (i.e., creating a set) and then manually filtering the values. The following example below shows you how to create a calculation that acts as a filter to compute the top 5 selling categories within each region. Create a nested sort Step 1 Step 2 Step 3 Step 4 Step 5 Step 6. Tableau Training.

We continue to make it available because the information is still valuable, but some steps may vary due to product changes. When creating a map view in Tableau Desktop 6.1 and earlier, location names contained in your data may exist in multiple countries/regions or states.
When the country/region or state is not specified for these location names, you may see the following warning message because Tableau is unable to plot the location on your map: For example, suppose you want to plot the city of Aberdeen. Aberdeen happens to be the name of two cities in the United States (U.S.), and the name of another city in the United Kingdom (U.K.). Because the country and states are not specified for the city of Aberdeen, Tableau is unable to plot the intended location and displays a warning message. In this example, adding the Country field will disambiguate Aberdeen at the country level. Embed Views into SharePoint (Microsoft SSPI) You can embed a Tableau Server view in a SharePoint page. To automatically authenticate Tableau Server users who access the embedded view you have two choices, both of which depend on which user authentication method was selected during Tableau Server Setup.
You can use either Active Directory with Enable automatic logon to authenticate Tableau Server users (also known as using Microsoft SSPI), or you can use Local Authentication—and then also configure Tableau Server for trusted authentication. This topic applies to the first option, where both Tableau Server and SharePoint are using Microsoft SSPI. If your Tableau Server is using Local Authentication, see Embed Views into SharePoint (Local Authentication) for steps.
Requirements Licensed users: Anyone who accesses an embedded view must be a licensed user on Tableau Server. SharePoint version: To embed Tableau Server views in SharePoint pages, you must be using SharePoint 2013. Embedding a View into SharePoint.

Lollipop charts: the search for the perfect mark (part one) Here’s the problem: I am visualising satisfaction rates over multiple dimensions. In almost all cases, satisfaction rates are high (between 70% and 100%). I want a visualisation that allows comparison over multiple dimensions that is also nice on the eye. Below is the result: a lollipop chart. Although I stumbled across this design by trial and error in Tableau, it is a chart type found elsewhere, eg on Chandoo’s excellent Excel blog.
What I thought I would do in this post is explain why I think it’s a great chart in this situation and how to do it in Tableau. To me, it’s a great way to reduce the data-ink ratio while retaining readability. Tableau’s default visualisation is the bar. How can we solve this? Maybe we should push the size slider to the max (and add a border). Given there’s too much ink, maybe the bar itself is the problem. We can get round this distance problem in a couple of ways. But we all know that an axis that doesn’t start at zero is a bad thing, right? Space: Forums. List of available online WMS services (Weather, Land Data, Place Names...)
