A category plot displays grouped data (scatter, line/scatter, bar graph). The data can be XY pairs, Many X, or Many Y. (For Many X or Y, the corresponding Y or X values are auto-numbered).

You can make global text and other attribute changes by selecting a graph, or pressing Ctrl+A to select everything on a page, then using the Tools and Text ribbons on the Graph Page tab.

This macro tests XY data pairs for equality of slopes. If the slopes are found to be insignificantly different then it tests for the equality of y intercepts. A pooled slope (intercept) is computed if the individual slopes (intercepts) are insignificantly different
