偶用gnuplot画图, 三条curve按出现的先后顺序分别
会是red, green, blue. That's the default setting
in gnuplot.
请问如何能customize gnuplot中的颜色设置呢?比如
偶想让第一条curve是 blue, 第二条curve是red, etc.
google了很久,发现这问题牵连到 .Xdefaults, X11的
一堆东西. Could anyone have experience on this
give some sample .Xdefaults/.gnuplot file? Thanks
a lot!

in your home directory .Xdefaults (if u don't have one, create one)
append
gnuplot*background: white
gnuplot*textColor: black
gnuplot*borderColor: black
gnuplot*axisColor: black
gnuplot*line1Color: red
gnuplot*line2Color: green
gnuplot*line3Color: yellow
gnuplot*line4Color: magenta
gnuplot*line5Color: cyan
gnuplot*line6Color: sienna
gnuplot*line7Color: orange
gnuplot*line8Color: coral
then, log out and re-login
or, xrdb -merge .Xdefaults

when giving a first plotting command in gnuplot after .Xdefaults is setup,
gnuplot may give the following complain --
gnuplot> plot sin(cos(x))
gnuplot: can't allocate 'sienna'. Using black.
gnuplot: can't allocate 'orange'. Using black.
gnuplot: can't allocate 'coral'. Using black.
Is there anyway to circumvent this problem? Also, the output .ps file still
stick to the old default color sequence, (i.e. "red","green","blue",...)no
matter how i modify .Xdefaults (the results from terminal x11 loo

this is due to you don't have these three colors: 'sienna, orange, coral'
in your system.
not sure about ps files, but i think you can use png or jpeg terminal and that
will have correct color

run "rgb" to see if you have these colors defined.
