The chart theme builder, which you use to create a general chart theme, organizes and presents properties in a similar way as the Format Page of the chart builder. Figure 12‑4 shows the Format Chart Theme page where you set formatting attributes for the different parts of a chart. The preview section shows your formatting changes for the selected chart type, which you choose in the Preview Type page.

Use the Script page to write event-handling code for a theme. This code applies only to HTML5 charts. It is ignored when the theme is applied to a BIRT chart. Information about writing event handlers is provided later in this chapter.
