You can easily annotate a report using text boxes that you can drag and drop onto the report. You can also add titles to your widgets, such as on a graph.

You add a text box the same way you add any widget to your report.

In the Text section, click and drag the Add text block button onto your report, then drop. You can then write in the text box.

Any widget you build you can add a title and sub-title to it. The option for a title and subtitle appears as you build a widget.
