While painting the graph, draw the actual function data.

Parameters:

g - the graphics2d object to paint in

image_fromX - first visible X coordinate of the Graph display area (= after subtracting space reserved for Y axis)

image_toX - last visible X coordinate of the Graph display area (= after subtracting space reserved for Y axis)

image_refX - X coordinate of the origin, in the display area

image_refY - Y coordinate of the origin, in the display area

xScaleFactor - conversion factor between data space and image space, image_x = xScaleFactor * data_x

yScaleFactor - conversion factor between data space and image space, image_y = yScaleFactor * data_y

startY - the start position on the Y axis (= the lower bound of the drawing area)

image_height - the height of the drawable region for the y values
