Plotting continuous Y values against binary X values

I am trying to create a scatterplot for which the X values take on only values 0 and 1. How do I format the X axis, so that only the values 0 and 1 are displayed, and so that the vertical axis is somewhere to the left of X=0?

Hi,

Not sure whether this is what you want, but have a look at the attached and let me know.
