Scatter Plot with 3 Axis, One a LinearColorAxis

Hi,
i am wanting to create a plot which has three axes: 1. along the bottom of one scale (LinearAxis); 2. along the left side (LinearAxis) of another scale; and 3. along the right side (LinearColorAxis) as another scale.

I am able to get the first two and then by adding a ScatterSeries with x,y DataPoints display data. However, I am wanting to color the points based on some other value z using the color scheme of the LinearColorAxis.

Can someone help me with a simple example of this?

Thanks
