Introduction

XYPLOT is a plotting and data analysis program for use by students, teachers, scientists, and engineers. It displays the results from your experiments or calculations in an interactive graphical environment. Fast plotting and a myriad of data manipulation and analysis features make XYPLOT an invaluable tool for visualizing and working with data.
