# Multi-variable Chart

## About our multi-variable charts 

The multi-variable chart allows users to select multiple columns for the x-axis. Each x-axis variable is divided into segments representing different data elements within that column. In the example below, drug tests are compiled on the x-axis while the stacks represent test results (resistant, susceptible, not determined, etc.) 

Enjoy a panel-specific legend for ease of interpretation of the different bar stacks as well as a panel-specific dropdown to drill down in specific columns of data!

## Creating your multi-variable chart

| <p><strong>Step 1:</strong> Select which columns from your metadata should be shown as bars in the x-axis of your chart. <br></p><p>This chart type allows users to make comparisons across multiple columns consisting of similar data elements. For example:</p><ul><li>Presence or absence of a certain mutation across multiple gene columns</li><li>Standard scores across multiple student columns </li><li>Weather patterns across multiple geographic columns </li></ul>                                    | ![](https://lh7-rt.googleusercontent.com/docsz/AD_4nXeQWLOxr_Lx_0uuks-WZC8oMj14ZTF9DIiSlDLQCMES0TGxoGdbvQf5Xg8J0Up-KmbLL0p5bnKJGNVnabrxMoPnV1o-Zi83RVgejt-zZE8BNHeIFxR3_Zj5Xaid5JjEcL9-W2r_8HgzzSoO-o1CKGdVYvSF?key=eWiUFSXUJbPgi8wi6uipZA)                                                                                                                                                                                                                                                                                                |

| <p><strong>Step 2:</strong> Select which data elements appear in each bar stack. Choose between showing all data elements present in each column, exclude blank values or choose from a list of data elements you want to appear in your chart. </p><ul><li>Option 1 (All values): Absent, Present, Detected with low coverage, Not tested, null </li><li>Option 2 (All values except blanks): Absent, Present, Detected with low coverage, Not tested</li><li>Option 3 (Custom values): Absent, Present </li></ul> | <p><img src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXcN5od505LZvpKEnyBPffL4T8CGyTSj2aqJFDnxphVaNaC--EVd5EFQhx_83603vwG3sKh5xwo6CrgTdea4Bf_Q-71GL4BkLhg2kxXmBbML0axOtL4mapYY5VXbrmLPvot7sAj8sWds7kMka5_JtHV2Oewd?key=eWiUFSXUJbPgi8wi6uipZA" alt=""></p><p><br></p><p><img src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXeJyW2FKS-FncGpJCLerYlgW5jiMhvdGgoyGh3frR9aCof3--67qdSY0_TL4QXSYl-IuMmqubzOf1zxI5wGpn7OZ2nS6ztp8HjIqDIHvjUuxXkT18Bl4NoegEjCSUPYLjqjHJgVjvowNdlmxNmlA83U0Uw?key=eWiUFSXUJbPgi8wi6uipZA" alt=""></p> |
