The caption is automatically generated by default, however, you can edit the caption by double clicking the Caption card. In Edit Caption dialog box, you can use change the font, size, color, and alignment and style.
Use the Insert menu to add automatic text such as page number, sheet name, and field and parameter values.
The caption can optionally be included when printing, printing to PDF, and publishing to Tableau Server. When you export the view as an image to another application like Microsoft PowerPoint, you can optionally include the caption.
