如何从迷你图工具提示中的日期中删除逗号?

How do I remove the comma from the date in the sparkline tooltip?

我想从闪亮的工具提示中删除日期中的逗号,但我需要将其保留在值中。 我不完全理解 jQuery Sparkline 格式。

Sparkling tooltip example

library(shiny)
library(dplyr)

ui <- fluidPage(

  htmlwidgets::getDependency('sparkline'),

  DT::dataTableOutput("table")

)

server <- function(input, output) {

    raw_data <- data.frame(date = 2000:2021,
                     value = sample(100:500, 22))

  data <- raw_data %>%
    # Create the sparkline
    summarise("value" = sparkline::spk_chr(c(value),
                                xvalues = date,
                                tooltipFormat = '{{x}}: {{y}}'))

  output$table <- DT::renderDataTable({

    cb <- htmlwidgets::JS('function(){debugger;HTMLWidgets.staticRender();}')

    DT::datatable(data = data,
              escape = FALSE,
              options = list(drawCallback = cb))
  })

}

shinyApp(ui, server)

如定义here,您可以将numberDigitGroupSep设置为空字符串:

data <- raw_data %>%
    # Create the sparkline
    summarise(
        "value" = sparkline::spk_chr(
            c(value),
            numberDigitGroupSep = "",
            xvalues = date,
            tooltipFormat = '{{x}}: {{y}}'
        )
    )
