Hi!

Is it possible to plot a BCG-Matrix [1] with Gnuplot, where the
points/circles have different sizes?

TIA & CU
Jürgen

Points can have different sizes, but you do not have any control over the
absolute size. That is, "pointsize 5" is always bigger than "pointsize 3"
but it is entirely up to the output device how big that is in inches or
pixels.

However, the CVS version has a new option "plot with circles"
that allows you to specify the radius of the circle either in graph
coordinates or as a fraction of the screen size.

See:
http://gnuplot.sourceforge.net/demo_4.3/circles.html

This plot style will be in the upcoming version 4.4, or you can build
from the CVS source code on SourceForge.
