Bubble Size

[cat123]

Can anyone tell me why the bubbles appear different sizes when you plot it sgplot and gplot?  You can tell the most on the smaller bubbles.  I haven't made any changes to the bubble size in either and the code really only has the variables and nothing else fancy.  The one with colored bubbles is sgplot and the one with blue bubbles is gplot.  Thanks!

These are two completely different technologies and graphing systems.  You will find differences in many other plots, such as Scatter, VBar, and so on.

Besides that, the SGPLOT Bubble statement uses BRADIUSMIN and BRADIUSMAX for lowest and largest bubble size for mapping the data min and max.  Default values are 7 and 21 pixels.  The scaling is NOT proportional.  That is, the slope of the scale line does not pass through zero.  This can be done using the GTL BubblePlot with the RELATIVESCALETYPE option.  This will force the scaling to be linear between zero and bubble max.  Bubble min will be a cutoff.
