我在一个情节中有一个图例,其中有一条线(来自 abline 语句)穿过它。我怎样才能使 abline 在图例附近变得不可见?这应该可以通过将图例背景设置为白色、无边框来实现,但我该如何实现呢?假设图表应如下所示:
windows.options(width=30, height=12)
plot(1:10)
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(4.8, 3, "This legend text should not be disturbed by the dotted grey lines")
让它更复杂一点:如果图例干扰了点图的点:我怎样才能实现 ablines 在图例附近变得不可见(如上),但点仍然可见?
windows.options(width=30, height=12)
plot(1:10)
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines, but the plotted dots should still be visible")
最后:有没有办法在图例语句中引入换行符?
