XY Graphs

Interaction Graph Options

Different line styles: For categoric factors, by default each will have a different color and different line style. Turning this off will still give different colors, but now all will have the same pattern.

Auto Adjust Y scale: Changes the Y axis scale if necessary when the factor settings are changed.

Polynomial and Factorial Graphs: Set the display to show interval estimates, LSD bars, or no (none) variance indicator on each type of graph.

Show End Points: Enable an indicator for the end point predictions where there may not be an actual data point.

Bands Displayed: What type of bands will appear on the model graphs. These settings have no effect unless Bands are enabled above.

Use Average LSD values for selected points: This will make the output look like an older version of the software.

Maximum LSD bars displayed: For some interaction plots involving many combinations the calculations of the LSD’s can be quite time consuming and very difficult to see. For this reason we provide a reasonable upper limit of 250 by default. Increase this if you have a high resolution monitor, and decrease it to speed up the creation of large interaction plots.

DFFITS/DFBETAS Limit Lines: The +/- 2 is the old functionality and used to keep graphs looking the same as an older version. Going forward use the model dependent limits.

Show 2D graph grid lines: Checking this will turn on a grid plotted at the tick marks of the X and Y axes. It is off by default to make the graph “cleaner”.

Show reference point on trace/perturbation plots: A dot will appear to indicate the where the reference combination is on the graph. It is only a visual queue for interpeting the graph.
