My guess, based on the information you provided, is that you should study Excel. Do you have any other requirements beyond having to use Excel?

Actually paul the thing is my program generates somewhere around 1000 values in an arraylist so just want to know that how do i connect my program with excel . Manually entering values and generating graph would be difficult .

You can use a library such as Apache POI to create Excel files from your data. Or you can write them into an existing empty Excel file that has the graph defined already.
