asked on # plot y=x^2+3

At first phase, I am hoping to develop a JApplet to plot a parabola with equation like y=x^2+3.

On a later posts, if I cannot make it on my own, I will post requesting help on plotting y=a*x^2 + b*x + c where a, b, c constants will be supplied by user.

Question: Could you give me the basic structure for me get going?

I am new in java. I can code but need help on the graphics.

Thank you.

(FYI: This is not a school project).

Create class

PlotPanel extends JPanel

and override the paint(g) method -- firts determine the hight and width of JPanel then

decide on some goo point for the origin and then divide your horizontal axis on

sufficinely small intervals calculate location of points and draw path through these

points - something like that should be more or less straightforward.
