Pie Graphs on Tuva
Lesson
A pie graph does not show individual cases. Instead, it shows aggregate frequencies for different categories of an attribute. This lets you explore the proportional relationship across the categories for how they comprise the whole. Creating pie charts on Tuva is very easy. Here are the steps: Creating a Pie Chart with a Single Categorical Attribute: Step 1: Click on any categorical attribute in the :ti[case-card] to color the data points in the graphing area by the categories of the chosen attribute. ![]700 Step 2: From the toolbar, choose :ti[pie] to create a pie graph. ![]700 You can also choose to display proportions or percentages for each category by adding these relative frequencies from the Count and Percent menu in the toolbar. ![]700 Creating a Pie Chart with a Single Quantitative Attribute: A traditional pie chart can be used to display the aggregate frequencies of a categorical attribute. But a Tuva pie graph can also display the categories of a quantitative attribute by converting the numeric values to numerical intervals and then displaying the aggregate frequency for each interval. Here are the steps: Step 1: Click on any quantitative attribute in the :ti[case-card] to color the data points in the graphing area by the categories of the chosen attribute. ![]700 Step 2: From the toolbar, choose :ti[pie] to create a pie graph. ![]700 You can increase the number of pie sections by clicking on the plus button on the top right of the graph. Similarly, you can decrease the number of pie sections by clicking on the minus button. Creating Multiple Pie Graphs with Two Attributes: You can also create multiple pie graphs on Tuva. These charts help you to discern patterns, if any, between two attributes. Step 1: Create a pie graph with a categorical or quantitative attribute of your choice. ![]700 Step 2: Drag and drop another categorical attribute on the x- or y-axis. ![]700 You can see how the health of the dog breeds varies depending on their friendliness. In the interactive tutorial that follows, you will explore the Man's Best Friend dataset and create your own pie graphs. ![]720
