问题描述
我有一个如下所示的数据文件:
1 1.0 0
2 1.5 0
3 0.0 1
4 1.2 2
5 1.0 1
6 1.1 1
第一列是我的X值,第二列是我的Y值,第三列是一个颜色。我希望每个线段都根据第三列进行着色。所以前两个线段将是颜色1,接下来是颜色2,下一个将是颜色3,最后两个线段将是颜色1。
我试过:
使用1:2:3与线条rgb绘制'file.dat'变量;
但是我的线条全黑。
这是可能的gnuplot?
谢谢,
Gabe
plot./file.datu 1:2: 3 with lines palette
希望这有助于您。
当我运行代码时,gnuplot无法通过rgb部分。
有关使用变量标签的示例,请参阅类似问题:

I have a datafile that looks like this:
1 1.0 0
2 1.5 0
3 0.0 1
4 1.2 2
5 1.0 1
6 1.1 1
where the first column is my X value, the second column is my Y value, and the third column is a color. I'd like for each line segment to be colored according to the third column. So the first two line segments would be "color 1", the next would be "color 2", the next would be "color 3", and the final two would be "color 1" again.
I tried:
plot 'file.dat' using 1:2:3 with lines rgb variable;
But my line was all black.
Is this possible in gnuplot?
Thanks,Gabe
This following works for me (gnuplot 4.4)
plot "./file.dat" u 1:2:3 with lines palette
Hope this helps.
When I ran your code gnuplot couldn't pass the "rgb" part.
For an example of using the variable tag see the similar question:GNUPLOT: dot plot with data depending dot size
with the useful examples found here:http://gnuplot.sourceforge.net/demo/pointsize.html
All the best

这篇关于在GnuPlot中的线图,其中行颜色是我的数据文件中的第三列?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
