gnuplot:如何设置烛台中晶须的颜色?

gnuplot: how to set color of the whisker in candlestick?

我正在绘制蜡烛图。如何将胡须的颜色设置为黑色?现在,它与盒子的其余部分相同。到目前为止,这是我的代码:

set terminal svg 
set output 'out.svg'
set key off  
set xlabel 'X'
set ylabel 'Y'
set title 'Data'

set xrange [0:4]
set yrange [0:100]
set tics scale 0.5
set xtics nomirror
set ytics nomirror

set style fill solid noborder
set linetype 1 lc rgb 'red'
set linetype 2 lc rgb '#009900' 
set linetype 3 lc rgb 'black' 
set boxwidth 0.75 relative # absolute

plot "data.txt"  using 1:2:4:3:5:( <  ? 1 : 2)  linecolor variable with candlesticks, "data.txt" using 1:6 with lines lt 3 

谢谢!

烛台图中的晶须与其他带误差线的图中的误差线具有相同的属性。例如

  set bars linecolor "black" linewidth 3
