Title: added parameters xval and yval to drawPointCallback and drawHighlightPointCallback

I added the parameters xval and yval to the drawPointCallback and drawHighlightPointCallback callbacks so I can use these values to draw a custom color or shape. For example, I draw all xvals before a certain date in one color, and all xvals after this date in another color.
