问题描述
我有一个ggplot2图形,显示如下:
请注意,网格或轴线不会通过色带显示。处理此问题的一种方法是更改色带的 alpha
属性;然而,这可以使较浅的颜色太浅。
另一种想法是将丝网/轴线画在丝带的顶部而不是它们的下面。我怎样才能实现这个渲染顺序?
当然,这个问题可能会被问到ggplot2生成的任何图。但复制粘贴命令说明了这个问题,如下所示:
ggplot(data.frame(x = sample( 1:100),y =样本(1:100)),aes(x = x,y = y))+ geom_point(size = 20)
ggplot在 theme()
中引入了一个选项, ,2015年6月18日。
只需添加到您的情节:
+主题(
panel.background = element_rect( fill = NA),
panel.ontop = TRUE
)
ggplot
文档。
I have a ggplot2 graph which appears as follows:
Notice that the grid or axis lines do not show through the ribbons. One way of dealing with this is to alter the alpha
property of the ribbons; however, this can make the lighter colours too light.
An alternative idea would be to draw the grid/axis lines on top of the ribbons rather than beneath them. How can I achieve this render ordering?
Naturally, the question could be asked of any plot generated by ggplot2. But a copy-and-paste command that illustrates the issue is as follows:
ggplot(data.frame(x=sample(1:100),y=sample(1:100)),aes(x=x,y=y))+geom_point(size=20)
ggplot introduced an option in theme()
that lets you do just that with pull number 993, on June 18, 2015.
Just add to your plot:
+ theme(
panel.background = element_rect(fill = NA),
panel.ontop = TRUE
)
There is an example in the ggplot
docs.
