Holy cow, I figured it out, and it's stoopid easy. It may not be that apparent at first glance though. All I needed to do was set the padding to 0 for my horizontal axis. It seems that by default, the padding for my top/secondHorizontal axis, which is a CategoryAxis, was 0.5. By Setting it to 0, it now mathches the scaling of my bottom horizontal axis. Done !!!
