It looks like in your example, dots of a single size are stacked to indicate response and the x axis of the plot is a circle. This should be doable using annotate but if it is really simple in R, then that sounds like the way to go. There is a chance that Rob Allison at SAS has done this but his site may take a while to search through.

His site is

I may play around with this when I have some time.

I found an easy way to do it in R, so don't spend much time on this. I thought maybe someone would have a macro already written.

I haven't found a great example online, but am attaching a Word file. (But I think only Nat will get that). I'll look for

I will look some more for something online

Can you point me to a sample? If we are speaking of the same general type of plot, I have used one to show the relative concentrations of pollutants entering a river at different points with the size of the dot indicating the level of concentration. I used Annotate to do this.

Does anyone know if there's a way to make a circular dot plot in SAS?

These are like regular dot plots, wrapped into a circle. They are useful with data such as time of day, or wind direction.
