Abstract

Sometimes a picture means a thousand words. It is hard to visualize how a graph of a function looks like if there is no way of plotting and drawing that function. Paper graphs are simple and reusable but there is a possibility of error. Hence, plotting and drawing a graph manually has been a nightmare for people, especially for students who have just started learning mathematics. What was needed is an easy way to combine the dependability of paper graphs and the accuracy and quickness of computer graphs. That is just what this project is about. 2-D Graph Plotter has been designed to meet not only the requirements of a plotting device (such as the speed, reliability), but it is also very easy to use and very cost efficient. The purpose of this report is to describe the design and the implementation process of this tool, as well as to show how its friendly user interface allows interactive data manipulation and graph creation. I will then point out its advantages (such as why it works more quickly and efficiently than other off-the-shelf tools), and how the tool should be improved and extended to maximize its benefit.
