Hi,

I am trying to overplot symbols on a region filled (with pale grey

color) between two curves.

For some reason the filled region is always ON TOP of the symbols so

that I don't see them..

(I wanted to use transparency with alpha, but then it is to build a

postscript figure which does not support transparency, so this requires

me to first plot the filled region and then overplot the symbols...)

here is an example:

sampVS = arange(0.,1.,0.02)

x = concatenate( (sampVS,sampVS[::-1]) )

alpha1 = 0.98486328

alpha2 = 1.28486328

y1 = alpha1 * sampVS / sqrt(1.+(alpha1 * sampVS)**2)

y2 = alpha2 * sampVS / sqrt(1.+(alpha2 * sampVS)**2)

y = concatenate( (y1,y2[::-1]) )

p = fill(x, y, facecolor=(0.9,0.9,0.9))

scatter([0.4],[0.4])

==> the symbol is hidden behind the filled region although it is plotted

afterwards...

thanks for any input here!!
