Passing values to paint()

[Tyx]

Is there any way that I can pass a variable to paint()? I am trying to make an applet of a real-time graph, and it's impossible to put labels on the axes, because the graph gets scaled at every repaint, so the y-axis changes position all the time. <br>So, I tried doing it from outside, scaling it once, and passing the scaling factor to paint() just once, since it doesn't change much. <br>But it's impossible...I can't get the width and the height of the frame if I do it outside paint. I tried creating another method with the values, and calling it from inside paint...no luck, since the values are zero, without the dimensions. And even if I find a way to do that, if then I want to maximise the graph window, since the scaling is not done in paint anymore, it won't rescale, as it does now. <br>I hope this is all clear, I'm fairly new in Java programming...does anyone have any ideas, or any applets of resizable scaled real-time graphs with numbered axes that I can look at? Thanks!

All of the information you need to paint with can be obtained by or given to the class that the paint method is a member of. Then at the next repaint the method has access to all the information required.<br><br>&gt; I hope this is all clear<br><br>No, it isn't.<br><br>&gt; does anyone have any ideas<br><br>Sure, show some of the pertinent code where the problem(s) occur, i.e.:<br><br>&gt; I can't get the width and the height of the frame if I do it outside paint. <br><br>Show the code where that fails and explain how and when it fails.<br><br>-pete
