Graph Plotting Applet

Interactive Graph Plotting Program - Java Applet.

Note: These instructions must be followed in strict order:

Maximum number of points is 40 pairs in each series.
Enter the number of pairs of points to be plotted for the series with the largest number of points.
Enter the first pair of 'X' and 'Y' values from the two series, convenient maximum and minimum values for the x and y axes, graph title, axes labels and titles for the two series. Click on the 'Plot' button.
Then enter the next pair of points in each series and click on the 'Plot' button. Repeat this step until all the pairs of points have been entered.
Either 'X' or 'Y' values MUST be in ascending or descending order.
Maximum length of title and axes labels: 40 characters.

To correct entries do the following after all the specified number of points have been entered:
Enter 99 in the 'Number of points' box,
Enter 1 or 2 in the 'X values First series' box, according to whether you wish to correct a value in series 1 or 2;
Enter the number of the point in the 'Y values First series' box to match where in the sequence the point to be changed is located;
Enter the required 'X' value in the 'X values Second series' box and the required 'Y' value in the 'Y values Second series' box and click on the 'Plot' button.
To make further changes keep repeating the previous 3 steps.
