![]() ![]() You can see that when we dragged Sales, it automatically summarized it by adding up all the sales values for each sub-category. So drag the Sales variable (in the Measures section) next to columns and the Sub-category variable (in the Dimensions section, under Product) next to rows.Ħ. Bar graphs are great for comparing categories. We are going to create a horizontal bar graph to compare the amount of sales for different sub-categories of products, with sub-categories along the y-axis and sales along the x-axis. ![]() Give it the name “Sales Bar” and press Enter.ĥ. ![]() Right-click on Sheet 1 at the bottom, select rename. To keep track of all the visualizations we are going to create, let’s rename our sheets as we go. Let’s start by making a simple bar graph. Okay, we have loaded in some data about a fictional superstore, so let’s start by creating some visualizations that are used to make comparisons. In terms of Tableau terminology, those areas that say filters or pages are called shelves, the marks area is called a card and when the variables are showing up in those areas, they are called pills, as they are shaped like a pill.Ĥ. The centre area is where you’ll be dragging and dropping your variables on to different sections, such as rows and columns, or to vary mark characteristics such as colour or size by your variable, or filtering by a variable. Dimensions are roughly qualitative data and measures are roughly quantitative data. On the left you can see our variables listed, categorized by Dimensions and Measures. Under Saved Data Sources, select Sample - Superstore.ģ. ![]() We are going to start with a built-in dataset. Now you should have a folder within the Workshop folder, TableauDatasetFiles, containing the data files required for this tutorial. Then you should be able to right click on the zip file and select 7-Zip, then Extract Here to extract it.Ĥ. On a PC, you might first want to install a program called 7-Zip. On a Mac, just double-click on the file to extract it. Different computers have different setups. Go to the Workshop folder and extract the files. Download the dataset files and save them to your Workshop folder.ģ. Right click on the desktop and select New and then Folder. In order to download and unzip the data required for this tutorial, please follow these instructions:ġ. You will need a few Excel files and a CSV file to follow along with this tutorial. There are some graphs in the introductory tutorial that are not covered in this tutorial, so feel free to consult both. Note: this guide builds on, and goes further than, the existing Introductory Tableau Desktop demo. ![]()
