The chart below has captions to add descriptive texts to the chart area. The 'Title', 'Subtitle' and 'Credits' are keywords to use theme-formatted captions.
Other customized captions can be added for further customization.
Here, we use:
a Title caption with no additional formatting
a Credits caption right-aligned and italics
a custom caption docked at bottom, blue tinted and 'Arial' font size of 10 pixels
