1) Define array of data and array of colors.

int[] data = { 16, 14, 16, 10, 4 };

int colors[] = { Color.RED , Color.LIGHTBLUE ,Color.YELLOW, Color.GREEN,Color.BLUE};

/////////////////////

2) Other parameters

int width = 200; // width of area where pie graph is drawn.

int height = 200; //height of area where pie graph is drawn.

int sum = 0;

int deltaAngle ;

int x = 0; //starting point where area of pie graph drawn (you can change this as per your choice)

int y = 0; //

int diameter;

//////////////////////

3)Calculation

sum = 0;

for (int i = 0; i < data.length; i++) {

sum += data[i];

}

deltaAngle = 360 * 100 / sum / 100;

if (width > height)

diameter = height - y * 2;

else

diameter = width - x * 2;

/////////////////

4)Paint function

protected void paint(Graphics graphics) {

graphics.setColor(Color.BLACK);

graphics.fillRect(0, 0, width, height);

graphics.clear();

int startAngle = 0;

for (int i = 0; i < data.length; i++)

{

graphics.setColor(colors[i]);

graphics.fillArc(x, y, diameter, diameter, startAngle, deltaAngle * data[i]);

startAngle += deltaAngle * data[i];

}
