A trigonometric plot

Heya, I've tried to make a program that plots a sinus curve.
The user is asked what width and scale he wants the plot to be.
The problem is that the scale is messed up and I would appreciate if someone could help me out

Code:

---

public class Trigonometry {

        public static void main(String[] args) {

                double[] sinusarray = { 0.3, 0.7, 1, 1.3, 1.6, 1.9, 2.2, 2.5, 2.8, 3.1,
                                3.4, 3.7, 4, 4.3, 4.6, 4.9, 5.2, 5.5, 5.8, 6.1 };
                sinus(sinusarray);
                System.out.print("scale: ");
                double scale = Keyboard.readDouble();

                System.out.print("width: ");
                double width = Keyboard.readDouble();

                plotFunctionstable(sinusarray, scale, width);
        }

        static void sinus(double[] array) {
                for (int i = 0; i < array.length; i++) {
                        array[i] = Math.sin(array[i]) / array[i]; //

                }

        }

        static void plotFunctionstable(double[] array, double width, double scale) {
                for (int i = 0; i < array.length; i++) {
                        double blanksteg = scale * (width + array[i]);

                        for (int j = 0; j < blanksteg; j++) {
                                System.out.print(' ');
                        }
                        System.out.println('*');

                }
        }
}

It seems to "work" in some sense.

Hard to tell without having a more clear idea of what you are trying to accomplish.

But this expression doesn't look exactly right to me: scale * (width + array[i])

P.S. "sinus curve"?
This is the first time I've heard anyone use that word related to sin functions.

This is a sinus: http://www.krystalplonski.com/wp-con...sal-cavity.jpg

sinusoid and sinusoidal are more typically used.

(Sure; "sinus" is the original Latin word, but one doesn't usually expect Latin in that context. ;-)
