In addition, new settings have been added to control the font and background of the labels. ![v1](https://www.statgraphics.com/hs-fs/hubfs/v1.png?width=1600&name=v1.png) Trellis Plots in DOE Wizard Trellis plots have been added to the response surface plotting section of the Design of Experiments Wizard. Trellis plots are segmented contour plots that show how the estimated response changes as a function of 3 or 4 factors. 2 continuous factors define the axes, while 1 or 2 other continuous or categorical factors are used to segment the plot.  ![v2](https://www.statgraphics.com/hs-fs/hubfs/v2.png?width=1600&name=v2.png) Transformations for Binary Data in DOE Wizard The logit and probit functions have been added to the transformations available in the DOE wizard. These functions are designed for modeling response data consisting of proportions. They have the effect of constraining all predictions to the \[0,1\] interval and of stabilizing the variance. In addition, predictions based on all transformations (including logarithms and the Box-Cox transformation) may now be plotted in either the original or transformed units. ![newsurface-2](https://www.statgraphics.com/hs-fs/hubfs/newsurface-2.png?width=1600&name=newsurface-2.png) New Operators for Reproducing Transformations Four new operators have been added to Statgraphics expressions to reproduce the transformations used in the DOE Wizard: BOXCOX, INVBOXCOX, LOGIT, INVLOGIT, PROBIT and INVPROBIT. Opaque Graphics Text Users now have the choice of a transparent or opaque background for all graphics text. If opaque, the color of the background may be specified. ![newpie](https://www.statgraphics.com/hs-fs/hubfs/newpie.png?width=1600&name=newpie.png) **Flexible Activation for Academic Site Licenses** 2 methods are now provided for activating academic site licenses, one designed for single computers and virtual machines and the other for a classroom of networked computers.
