[Gnuplot-bugs] undefined function: xtic

[Rajiv C. <raj...@gm...>]

Hi friends,

I have installed Gnuplot 4.2 in my Ununtu Machine. Its running fine but when
i am trying to run Histrogram demo its giving me error as following:

gnuplot> set xtics   ("1891-1900" 0.00000, "1901-1910" 1.00000, "1911-1920"
2.00000, "1921-1930" 3.00000, "1931-1940" 4.00000, "1941-1950" 5.00000,
"1951-1960" 6.00000, "1961-1970" 7.00000)
gnuplot> set title "US immigration from Northern Europe\n(same plot with
larger gap between clusters)"
gnuplot> set yrange [ 0.00000 : 300000. ] noreverse nowriteback
gnuplot> plot 'immigration.dat' using 6:xtic(1) ti col, '' u 12 ti col, '' u
13 ti col, '' u 14 ti col
         undefined function: xtic

So what should i do to correct this error?

Cheers,

Rajiv
