Bubble Plots (size of bubbles)

deleted_user — Wed, 26 May 2010 15:15:44 GMT

I'm wondering how to ensure that the size of bubbles are not only proportional to each other within a figure, but across figures.

Right now I have several figures, and for example, one figure where a bubble represents 50 observations is smaller than a bubble in another figure that represents 30 observations.

Does anyone know of a way to address this?

Thank you in advance!

I'm not sure that "proc gplot" bubble charts have a way to guarantee that the bubbles are scaled the same in different charts.

When I need to have total control over bubble sizes (whether in gplot or gmap), I use annotate's "pie" function. An annotated pie, with style='solid' is a solid bubble, and style='pempty' is an empty circle. I "normalize" my data values against a maximum, and then use those values to control the 'size' (radius) of the pies.

have you tried the UNIFORM option? aaaaah : that : is: just : for : scaling : indexes
