The Dashboard tab of Dashboard Designer allows you to configure a chart based on the data configured in the Data Source tab. Here you can specify the chart type and axis fields, as well as configure the style of labels, legend, tooltips, and series. With the help of the Advanced tab, you can extend the behavior of your chart by handling the pre-render event and tuning the configuration object via JavaScript. When the configuration is ready, you should click the Process button to visualize the data.

Note: You should configure and process the data on the Data Source tab first to build a chart based on it.
