[Gnuplot-py-users] How can I make x or y axis with different colors number?

[Veelion C. <ve...@gm...>]

Hi, All

I want to plot a chart of my data. I want the xtics with different colors.
for example, my x data is
          -3, -2, -1, 0, 1, 2, 3,
I want the text data less than 0 appears red, 0 is green, and large than 0
is blue, which seems like,
          -3(r), -2(r), -1(r), 0(g), 1(b), 2(b), 3(b),
I tried to use
          'set ytics tc rgb "#FF0000" (%f %f %f)' % (-3, -2, -1)
          'set ytics tc rgb "#00FF00" (%f)' % (0)
          'set ytics tc rgb "#0000FF" (%f %f %f)' % ( 3,  2,  1)
but only the last one take effect, why?

How can I make x or y axis with different colors number?

Thanks,
veelion
