R highcharter x轴日期问题

Question

我有一个包含月末数据的数据框。我使用的是堆积柱形图，但 x 轴日期标签有问题。例如，它在三月列下显示四月。

library(highcharter)
df = data.frame(Date = as.Date(c('2020-03-31','2020-03-31','2020-04-30','2020-05-31','2020-05-31','2020-06-30')), Value = c(1,2,3,4,5,6), Country = c('US','Mexico','US','Canada','US','Canada'))
hchart(df, "column", hcaes(Date, Value, group = Country)) %>%
   hc_plotOptions(column = list(stacking = "normal"))

我试图通过添加 hc_xAxis(type = 'datetime', labels = list(format = '{value:%m-%Y}')) 来指定类型和标签，但没有帮助。工具提示显示正确的日期。

一个简单而有价值的解决方案是将日期转换为字符。

library(highcharter)
 
df = data.frame(Date = as.Date(c('2020-03-31','2020-03-31','2020-04-30',
                                 '2020-05-31','2020-05-31','2020-06-30')), 
                Value = c(1,2,3,4,5,6), 
                Country = c('US','Mexico','US','Canada','US','Canada'))
 
df$Date <- as.character(df$Date)
 
hchart(df, "column", hcaes(Date, Value, group = Country)) %>%
   hc_plotOptions(column = list(stacking = "normal")) %>%
   hc_xAxis(type="category", categories=unique(df$Date))
