Using Additional Graphics

In Design mode, double-click a chart, then right-click and select Additional Graphics.

On the Global Trend tab you define how the trend for the data series is displayed. On the Line Chart tab you define how to display specific values of the data series, and the differences between them.

Global Trend
A global trend indicates whether the overall trend of the data values is increasing, decreasing or constant. In contrast, a line chart represents the trend of an individual data series. Unlike trend lines, a global trend does not follow specific data points on a chart.
