public abstract class SimplePlot

extends Plot

A simple single axis, single data plot. An t variable is predefined in the dataset (data) corresponding to the x-axis, so that body() method can return an expression based on t. A preamble() method is provided for any other definitions.

In general the plot is assumed to be a String composed of a preamble, a plot command and some post commands or data. The preamble() method represents the information required before the actual plot command, and the body() method represents the part that will appear as the body of the plot command. The range of the plot that will appear as part of the plot command is kept as the range attribute.

As a simple example here is how to plot the y = t + 5 graph:

 class MyPlot extends SimplePlot {
   MyPlot(Range range) { super("My plot!", range); }
   String body() {
     return add("t","5");
   }
 }
