title: ZedGraph v. 5.15, multi y-axis alignment
body: <p>The issue I have is when using two Y-axes (y1 and y2), wherein the y1 value is: (min,max) = (zero,positive) and the y2 value (min, max) = (negative, positive), in such case, the zero marking of y1 coincides with the max (negative) value of the y2 axis (through the x-axis), that is the problem since I want zero point of both y-axis to flush together.</p>
  
  <p>If I knew the value of min and max for both y-axes then this problem could be fixed easily, but I only know whether the range starts from positive or negative value, not the value itself.</p>
  
  <p>Note that this problem is not there when both y-axes have values (data points) above zero. They automatically align such that both their zero points passes through the x-axis.</p>
