Plotting a graph in Excel

I have to take some values close to 1000 and then plot a graph in excel , so i was wondering if somebody could tell me what exactly to study ?
Thanks in advance .

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.

You could just write the values to a CSV file and then exec Excel to oepn the file and generate the graph.

But if I was doing this, I would generate the CSV file and then run R to generate the graph.
