How to plot contours using radial cordinates?

Hello

I want to plot contours with radial cordinates i.e. THETA (angle value) and radius value (distance vale) around a point.

I will be having values in following format:

THETA DISTANCE VALUE

NOW i need to plot contours. HOW to proceed?

I am new to SWING or AWT, please guide me how to start?

I don't know if there is a plotting method in the java api for polar coordinates. I want to think I saw one but here is the formula for converting between.

Code:

---

// polar to Cartesian
double x = Math.cos( angleInRadians ) * radius;
double y = Math.sin( angleInRadians ) * radius;

// Cartesian to polar.
double radius = Math.sqrt( x * x + y * y );
double angleInRadians = Math.acos( x / radius );

Thanks a lot for feedback.

Well what about the next step i.e. HOW TO PLOT CONTOURS?

I am interested in plotting 2D contours only either line contour or colour contour.
