plotting graphs

Hi, I'm developing a GUI with several forms, one of which contains a jLabel that displays a JPEG image of a graph as it's icon. How do I go about plotting a simple 2d curve on that image from a set of data? I know of drawLine etc, but how can I do that on a jLabel?
Many thanks!

He said he wanted to draw some graphics on a JLabel, well that's how. Maybe you should think a little harder before posting stupid replys. Besides, if you didn't even know what I was talking about, why did you even post? It was obvious that helped...Now stop taking away from other people's posts.

i was just trying to learn something

i don't know what he means my JLabel...i'd like to know

i don't know how that one line of code you gave him answers his question

it looked like only part of an answer...

ohhh Sorry dude, I thought you were like trying to insult my intelligence or something....Dang, I hate it when I do that...Really, I am sorry for being an a$$...please forgive me...

Anyways,

JLabel, is a component in swing...It's like any other label, in any other programming language..All it does is display information, and in matt's case, he's wanting to draw on top of the component...So, in order to do that, he has to override the paintComponent method...And no, it doesn't fully answer his question, it answers only part of it...I'll try answering the rest of it later...

Again, I'm really sorry..I thought you were trying to say that I didn't know what I was talking about! sorry :o

Are you talking about not answering the curve part? Could you just drwa multiple lines making it appear to be a curve only being made up of line segments.

its no biggie, appreciate the information

i still don't have a complete grasp of what it is you guys are trying to do

but i have more to go by now, i need to look up JLabel, Swing, and basics of plotting 2 dimensional curves in java



Matt,
i was reading up on Java "Java for Dummies" a few weeks back and it spoke on using drawline which was some type of an object in one of java's built in libraries

from what i remeber it basically spoke on how "drawline" illustrates the grid of an applet by dragging the mouse from coordinates (x, y) and droping it to (x2, y2).

Is that what you mean my drawline (you'll have to excuse me i don't even own a computer, i just keep read this stuff until i can afford one)?

You can draw an arc in java, I guess that would be the same thing as a curve:

Somthing like... Graphics.drawArc(//code);

That's probably not a bad idea, although I would check out the drawArc() method first, and if that didn't work for him, then doing what you said certainly would.
