Plotting a graph in Java Netbeans

[at221]

Hi all 8) ,

As you can see from my profile I am a new user of NetBeans. I have some experience in Java but my knowledge is very limited. I have tried using bluej and ecllipse before getting my hands on NetBeans, and from an amateur I have to say NetBeans is the most user-firnedly without compromising functionality.

I have gone through several tutorials for netbeans particularly swing and GUI. I am a complete noob when it comes to graphics in Java but what I want to do now requires more knowledge in this area.

Bascially, I am trying to plot a graph of values (y-axis) against time(x-axis). The data is stored in an excel spreadsheet and has over 8000 entries. If I were to plot this as a line grap, what will the best way in achieving this?

Value Time
------- ------
3300 0000
2110 0001
2222 0002
324 0003
1242 0004
. .
. .
. .

Do I need to convert the spreadsheet to something else and is there a way in NetBeans to do this graphically in a design panel, like for the GUI?

Any help and advice will be appreciated.

Thanks
