从 ggplot2 转换时，Plotly 绘图未正确呈现

【中文标题】从 ggplot2 转换时，Plotly 绘图未正确呈现【英文标题】：Plotly plot is not rendering correctly when it is converted from ggplot2 【发布时间】：2021-12-11 22:38:51 【问题描述】：当我从 ggplot 转换为 plotly 时，构面图上的日期似乎不太适合页面。我希望在最后一个多面图上的页面末尾和 x 轴上的日期之间获得更多空间。我试图动态地做到这一点，但它似乎不起作用。有谁知道解决这个问题的方法吗？
这是我的代码：
library(ggplot2)
library(plotly)

这是我的意思的图片（突出显示的部分是我在说什么）：
【问题讨论】：
【参考方案1】：不完全确定您所说的“x 轴被切断”是什么意思（因为从您的图片中很清楚实际上可以看到 x 轴和刻度值等）。
我认为有一个问题是您的 Dates 列是字符。您可以通过以下方式解决此问题：
test_data <- test_data %>% mutate(Dates=as.Date(Dates, format="%m/%d/%Y"))
要在下面添加空格，您可以使用layout 和margin：
ggplotly(p, height = chart_height, tooltip = "text", xaxis = list(automargin = T)) %>%
layout(margin=list(b=50))
【讨论】：
我试图在页面末尾和 x 轴上显示的日期之间留出更多空间。我会尝试在问题中澄清这一点。 好的，这很有帮助 - 您可以在布局中使用边距以上是关于从 ggplot2 转换时，Plotly 绘图未正确呈现的主要内容，如果未能解决你的问题，请参考以下文章
