Themes determine the color and formatting of all visualizations in a Tabulation report. Pyramid ships with several out-of-the-box themes, and Admins can edit these themes and configure new ones from the Admin console.
Choose a report theme from the Themes menu in the Design ribbon:
Users can override theme colors and formatting for the current Tabulation by changing things like report background color, visualization background color, report title, and axis labels, via series editing.
Formatting preferences override not only the current theme, but any subsequently selected theme in the current Tabulation. To discard formatting changes and revert to the default formatting, click Reset Formatting from the Design ribbon.
