Math equation in Java Applet

[calnastic]

Hi,
I am trying to design an applet to draw parabola. The equation displayed is something like:
y = 3x^2 + 5x + 7
which is ugly.

Is there a way I can display the formal math equation? Like this:

How are you displaying it? Using a JLabel? A JTextField? The Graphics.drawString() method? Something else?

In short, the answer is yes. But it depends on how you're doing your drawing.

I am using a JLabel

In that case, you could probably use HTML.

What do you mean with ugly? I guess that it does not look smooth.

You can use a plotting library. Check this:

I was under the impression that he was talking about the text display of the actual equation, not the graph itself. In which case, HTML tags might work. I could be wrong though.

I can be wrong too :) I noticed the second part of the message later..

html sucks; look what my expression transmogrifier did to the OP's example:

-<i>x</i><sup><font color=\"#8000\">2</font></sup>&minus;<font color=\"#8000\">6</font>&middot;<i>x</i>+<font color=\"#8000\">7</font>

It can't even do double (or more) subscripts; it may be adequate for simple single superscripts, but that's about it. I wonder if a LaTex package exists for Java ...

kind regards,

Jos

Good question! Our friend google returned this:

@ administrator:
I just tried it with your link. It works. I have a JButton now with a complicated formula on it (as an icon). Now I seem to have to learn TEX to make formulas other then this example.
@OP:
I had some difficulty finding an example. I used Feature Requests - JAMWiki Java Wiki Engine If you need more help, I'm an expert now

That's cute; I'll give it a try; thanks for the link.
