Effect plots work by identifying high-order terms in a generalised linear model, a statistical technique. Once these terms are identified fitted values are derived and plotted for the relevant groups.

Line chart: Curves
This is an example of the use of a line chart to plot mathematical functions.
The set of line graphs shows how demographics of students in American schools have evolved in the last two decades. Here, New York City schools is selected, compared with New York State schools (gray line).<br /><br />The blue and gray lines are almost parallel everywhere, which tells us that in terms of the change in demographic composition, New York City pretty much resembled New York State during this entire period. <br />However, in terms of demographic composition, rather than the change in composition, New York City schools are very different from the rest of the state, in that the proportion of white is lower by a third while that of minorities are much higher, especially black and Hispanic students.<br />State-wide (as well as city-wide), black and white students have been declining as a proportion while Hispanics and Asians have increased. <br />The extent of the change is immediately visible, Asians have jumped from 7% to 14% for example.
