They use hold on and plot the data series as usual. The following is an introduction for producing simple graphs with the R Programming Language. In addition to the x, y (and z) values, an additional data dimension can be represented by a color variable (argument colvar ). This variable differs from normal by a lot, g 1 = 2. There's a box-and-whisker in the center, and it's surrounded by a centered density, which lets you see some of the variation. Then, instead of representing this number by a graduating color, the surface plot use 3d to represent dense are higher than others. Although we ran a model with multiple predictors, it can help interpretation to plot the predicted probability that vs =1 against each predictor separately. The best I've found is this example, but it uses Python instead of R. Therefore, it is defined as the set of all points in space that are equally distant from a center.
