绘图R图上的纸边框 [英] Paper border on plotly R graph

问题描述

不确定R的plot_ly函数是否具有此功能(我还没有找到它)，但是想通了. Plot_ly确实有一个paper_bgcolor参数，该参数可以更改绘图所在纸张的颜色，例如:

Not sure if R's plot_ly function has this capability (i havent been able to find it), but figured I'd ask). Plot_ly does have a paper_bgcolor parameter that changes the color of the paper that the plot is on, as such:

mydf = data.frame(x = 1:5, y = 1:5)

plot_ly(mydf) %>%
  add_trace(x = ~x, y = ~x, type = 'scatter', mode = 'markers',
            marker = list(size = 24)) %>%
  layout(paper_bgcolor = 'red')  

我对更改纸张颜色不感兴趣，但是对纸张边框感兴趣.也就是说，我想在纸的外边缘周围放一个红色的盒子.有人知道这样做的简单方法吗?

I am not interested in changing the paper color, but rather the paper border. That is, I'd like a red box around the outer edge of the paper. Does anybody know a simple way to do this?

编辑-我想我可能必须为此使用grid包，也可以使用grid来完成，但是我首先好奇是否有可能不合并其他包.

EDIT — I think I may have to use the grid package for this / it could be done with grid, but I'm curious first if it's possible without incorporating another package.

推荐答案

一种可能性是修改Plotly使用的CSS文件.

One possibility would be to modify the CSS file used by Plotly.

• 找到存储plotly-min.js和CSS文件的目录的位置

• Find the location of your directory storing the plotly-min.js and the CSS file

p <- plot_ly()
p$dependencies[[4]]$src$file

输出:

Output:

1 "/that/is/my/directory/Documents/R/win-library/3.4/plotly/htmlwidgets/lib/plotlyjs"

1 "/that/is/my/directory/Documents/R/win-library/3.4/plotly/htmlwidgets/lib/plotlyjs"

转到此目录并将plotly-htmlwidgets.css复制到新文件，例如plotly-htmlwidgets_red.css

Go to this directory and copy plotly-htmlwidgets.css to a new file, e.g. plotly-htmlwidgets_red.css

将以下行添加到新文件中

Add the following lines to the new file

div.svg-container {
  outline:5px solid red;
}

请告诉我们使用新的CSS文件

Tell plotly to use your new CSS file

p <- plot_ly()
p$dependencies[[4]]$stylesheet <- "plotly-htmlwidgets_red.css"
