Introduction - Drawing a plot
Drawing is done in drawing contexts that is compatible with the dimensionality of the variable. The "1D Plot" drawing context is for standard x-y plots. The bottom portion of the script window contains all the drawing windows connected to that script. Closing the drawing window will hide it. You delete the drawing context by dragging its entry from the script window to one of the recycling bins.
A variable can be added to a drawing context by dragging it into the command portion of the drawing window. This action will create a "Plot" drawing command and connect the variable to that command.
