我在R中用线条和散点以及填充区域变量制作了一个Plotly图。 X轴是以as.POSIXCT格式化的日期和时间,格式为="%Y-%m-%d%H:%M:%S"。每隔10分钟就会有2个月的数据。 Y轴是单位数。
我将图表整合到闪亮的仪表板中。我想使用daterangeInput来选择X轴的日期范围。但我无法弄清楚如何将daterangeInput集成为反应性/交互式。
任何帮助将不胜感激!
Plotly图表,已合并:
graph <- plot_ly(master, x = date, y = arrival.one, name = 'One Arrival', visible = "legendonly") %>%
add_trace(x= date, y = arrival.two, name = 'Two Arrival', mode = 'lines', visible = "legendonly" ) %>%
layout( xaxis = list(title= "Date and Time",
rangeslider = list (type = "date")))
用户界面:
ui <- dashboardPage(skin="black",
dashboardHeader(title = "Rack Filling"),
dashboardSidebar(sidebarMenu(
menuItem("Dashboard", tabName = "dashboard", icon = icon("line-chart")),
menuItem("Staffing", tabName = "staffing", icon = icon("male")),
dateRangeInput("inDateRange", "Date range input:")
)),
服务器:
server <- function(input, output) {
output$graph <- renderPlotly({graph
})
output$event <- renderPrint({
??????????
答案 0 :(得分:2)
在server
函数中,每次更改DateRange时都必须创建一个过滤器来过滤数据集。你称之为反应性来绘制你的情节:
server <- function(input, output) {
reactiveMaster <- reactive({
master %>% filter(date>=input$inDateRange[1] & date<input$inDateRange[2])
})
output$graph <- renderPlotly({
plot_ly(reactiveMaster(), x = date, y = arrival.one, name = 'One Arrival', visible = "legendonly") %>%
add_trace(x= date, y = arrival.two, name = 'Two Arrival', mode = 'lines', visible = "legendonly" ) %>%
layout( xaxis = list(title= "Date and Time",
rangeslider = list (type = "date")))
})
}
