In this tab you can create and use a dashboard with charts to analyze your workflow data.
On the left side, you will see a list with all your metadata and the models you added to your workflow.
Under each metadata or model, you will find a list of all the available values with their corresponding count (how many texts or snippets have that particular value). Besides, you can click any of the values in order to just display the data that matches that particular value. This is basically the way for you to slice and dice the data.
On the right side, you will find all your charts. By default, when deploying a workflow, it will auto-generate some charts for you. But you are also able to switch to the Edit Mode, where you can modify, delete, or add charts.
