Appendix C A Graph with Labeled Axes

Printed axes help you understand a graph. They convey scale. In an earlier chapter (see Readying a Graph), we wrote the code to print the body of a graph. Here we write the code for printing and labeling vertical and horizontal axes, along with the body itself.

• Labeled Example
• print-graph Varlist: let expression in print-graph.
• print-Y-axis: Print a label for the vertical axis.
• print-X-axis: Print a horizontal label.
• Print Whole Graph: The function to print a complete graph.
