One way of interpreting what you wrote is to plot y=x*sin(x). For the
rotation bit see

This is more of a math question than a charting one. I am trying to plot the
sin curve rotated by 45 degrees. I started by plotting points for the
equation y = x + sin(x). This resulted in a skewing of
the curve. I want the sin curve to be determined by the distance traveled
along and symmetrical around the line y = x.
