Hi

a colleague of mine found that triangles on larger sizes don't show the
right data point. It is not in the center of the triangle.
That's because we don't use equilateral triangles.

For now I would say skip triangles if you want to show an exact point of
your data or create a usersym for an equilateral triangles.

pro test_plot_symbol_center_of_mass
tek_color
plot, xrange=[0,10], yrange=[0,2], /nodata, [0], [0]
for i=1L, 7 do begin
oplot, [0.5]+i, [1], symsize=4, psym=i, color=2
oplot, [0.5]+i, [1], psym=1, symsize=0.5, color=4
endfor
end

cheers
Reimar
