Stretched Bar Charts
Lesson
A stretched bar chart is the most effective graph type when it comes to comparing proportions among the categories of a group. As the name indicates, each bar is stretched to the same length. The length of the subsections in a single bar represent the relative contribution of each category in the group. You can create different types of stretched bar charts using different combinations of attributes on Tuva based on what you are investigating. Creating a Stretched Bar Chart with a Single Categorical Attribute: To create the simplest stretched bar chart, click on a categorical attribute in the :ti[case-card]. Next, from the toolbar, choose :ti[stretched-bar-chart]. ![]700 Your finished graph will look like this: ![]700 Each bar section represents the proportion of a given category in the whole group. Creating a Stretched Bar Chart with a Single Quantitative Attribute: You can also create a stretched bar chart by applying a quantitative attribute to the Legend Area. Click on a quantitative attribute in the :ti[case-card]. Next, from the toolbar, choose :ti[stretched-bar-chart]. ![]700 Your finished graph will look like this: ![]700 You can also create a variety of stretched bar charts using different combinations of categorical and quantitative attributes. Here are a few examples: Creating a Stretched Bar Chart with Two Categorical Attributes: Here are the steps to creating a stretched bar chart with two categorical attributes. Step 1: Click on a categorical attribute or drag and drop it in the Legend area and choose :ti[stretched-bar-chart] from the toolbar, to create a basic version of the graph. ![]700 Step 2: Drag and drop another categorical attribute on the empty axis. ![]700 Your finished graph will look like this: ![]700 In the interactive tutorial that follows, you will create these different types of stretched bar charts and also learn nuances such as dragging categories from the legend to rearrange the bar sections, annotating the bar sections with absolute and relative values and displaying bar totals. ![]720
