Example: A Stable Process that Wasn't

The data for Figure gif are in the SAS data set SASDATA.WASHER5. To create Figure gif select Scatterplot ( Y X ). In the resulting dialog box THICK choose as the Y variable, ORDER as the X variable and MACHINE as the Group variable. The result is the three plots you see, but aligned horizontally rather than vertically. In addition, the vertical axes of the plots differ. To get the vertical axes to line up, on the graph window select Edit:Windows:Align. Use clicking (on the bounding box of the plots) and dragging to place the graphs in the vertical configuration shown. Figure gif was done in exactly the same way using the data in SASDATA.WASHER7.
