Use the Grammar Panel to Add Data to the Visualization
After you’ve selected the datasets for your workbook, you can begin to add data elements such as measures and attributes to visualizations.
If you haven't already created a visualization, you need to create one. See Create a Workbook and Add Visualizations.
You can select compatible data elements from the datasets and drop them onto the Grammar Panel in the Visualize canvas. Based on your selections, visualizations are created on the canvas. The Grammar Panel contains sections such as Columns, Rows, Values, and Category.
