You created a visualization! Now, let’s see if we can create a stacked bar chart, the way we did with Excel. (This palette of charts is called the Show Me window, in Tableau’s parlance.) Now that you have measures, you have some chart options! Click on the bar chart. You’ll also notice that highlighted options appear in the palette of chart types on the right-hand side of your window. Once you’ve dropped the “Number of Records” measure, you’ll see that they’re nicely summarized for you in the table you created. Drop it in the second column of the table, where the values are currently represented as “Abc.” 6. Click on this measure and drag it to the table on your canvas. Since each record corresponds to a grant, that’s the one we want. You’ll notice a measure called Number of Records. This means that these are numbers that Tableau has calculated for you. You’ll see that they contain the word generated next to them in parentheses. Scroll to the bottom of the Data column, and look at the measure types that are in italics. As we did when we used Excel to create a Pivot table, we want Tableau to summarize the values. We want Tableau to create a chart that visualizes the number of grants awarded per arts discipline. There’s a reason for that: Tableau doesn’t know what you want it to count. It’s not hugely exciting you just see a list of arts disciplines. Get started by clicking on Applicant Arts Discipline and drag it into the main section of the sheet (the canvas). Tableau will often provide recommendations based on these data types. Measures consist of numeric information: values that can be added up. Tableau divides your content types (that is, your columns) into dimensions and measures. Do that by clicking on the orange Sheet button in the lower left-hand corner. It should look pretty familiar! In Tableau, you begin visualizing data by creating a Sheet. Then navigate to the file you downloaded earlier and double-click to open it. Even though our Iowa Arts Council Grants file opens in Excel, it’s saved as a CSV. Choose your data sourceĪfter opening Tableau, you’re presented with a list of file types you can choose to work with (“connect”). For this exercise, you will need the Iowa Arts Council Grants data CSV file, which you can download at this link. Here is a preview of what we’ll make. At the end of this tutorial, you’ll find information on how to publish it to the web. We will use it today to make two charts, which we’ll combine into a dashboard. However, you do not need to create an account in order to use Tableau Public on your own computer. In addition, when you share a Tableau Public visualization, any viewer will be able to download the underlying data, unless you purchase a “premium” Tableau Public subscription. That means they will be freely available on the web, and you will need to create a Tableau account in order to do this. It’s free to download and use, but, aside from screenshots, the only way to share Tableau Public visualizations is to publish them to the Tableau Public website. There are several things to be aware of with regard to Tableau Public. Tableau Public is the free version of this tool. Tableau is a powerful data visualization tool, in heavy use among both laypeople and data professionals.
