【中文标题】我想让 r 条形图的图例框水平，但 ncol 不起作用

【英文标题】：I want to make the legend box horizontal for r bar plot but ncol is not working

【问题描述】：

这是我用于绘图的代码

barplot(read_comments_vs_influenced, xlab='Do you usually read comments under YouTube video clips?',ylab='Count',
        main=str_wrap("How far comments influence respondents' opinion for each category in reading  comments under Youtube videos",width = 110)
        ,legend=rownames(Age_vs_platform_follow_artists),
        args.legend = list(x = "topleft", cex = 0.4) ) 

我想让图例框水平以适合图表或使框更小而不影响图例内字体的大小 我尝试使用 ncol=3 但它给了我一个错误：ncol not a graphics argument

【参考方案1】：

这应该可行：

barplot(read_comments_vs_influenced, xlab='Do you usually read comments under YouTube video clips?',ylab='Count',
        main=str_wrap("How far comments influence respondents' opinion for each category in reading  comments under Youtube videos",width = 110)
        )

legend("topleft", legend = rownames(Age_vs_platform_follow_artists),
        ncol = 3, cex = 0.4)

也许ncol 放在括号的错误一侧？
