我想在 for 循环中的 ggplot2 中绘制多个 geom_line，所以我能够绘制线条但面临着色问题。 任何人都可以建议怎么做

Question

I want to plot multiple geom_lines in ggplot2 in a for loop. I am able to plot lines but am facing problem in coloring them. can anyone suggest how to do this?

pp=ggplot(a,aes(x=a$Nucleotide_position),y=data[,1:(length(a)-1)])
for (i in 1:(length(a)-1))
{ 
    pp=pp+geom_line(aes(x,y),data=data.frame(x=a$Nucleotide_position,y=a[,i]))
}

print(pp)

Answer 1

插入 aes(x,y, color = factor(x)) 或 factor (y) 不清楚你的数据框是什么样子的。
