Extending the Graphics class with drawLine (double, double, double, double)

Problem: // where the story begins The drawLine (int, int, int, int) method in the Graphics type is not applicable for arguments (double, double, double, double)

g.drawLine ((int) 10 * xi, (int) 30 * yi, (int) 90 * xi, (int) 30 * yi);
// where xi is the width of the Scale and yi is the heightScale

as you can see he's crappy

Actual prototype:
public abstract void drawLine (int x1, int y1, int x2, int y2)
Draws a line, using the current color, between the points (x1, y1) and (x2, y2) in this coordinate system of the graphics context.

What I would like to do:

g.drawLine (double x1, double y1, double x2, double y2);

or

g.drawLine(int x1, int y1, int x2, int y2, double widthScale, double heightScale);
