[Gnuplot-info] gnuplot + latex + histogram = help!

[Sabino <sab...@gm...>]

Hi,
i'm making an histogram with multicolumn. I'm using the following
gnuplot code to generate che histogram:
plot 'data.dat' u 2 title 'A', u 3 title 'B', u 4 title 'C', u 5 title 'D'

but in latex all the histogram bar are black!
I try using:
plot 'data.dat' u 2 title 'A' fs pattern 1, u 3 title 'B' fs pattern
2, u 4 title 'C' fs pattern 3, u 5 title 'D' fs pattern 4

but this time, odd patterns are black and even patterns are white.
There is any other solution to distinguish those bars? Like a
grayscale...or pattern for latex?

Thank you!
