如何在Shiny-折线图中进行数据集的反应函数特别是不了解如何将数据集应用于reactive()
函数以响应所选输入]
然后s 如何用折线图显示该类型,目的是学习闪亮的用法。我也不知道如何在普通ggplot中应用。# sample data df <- economics %>% select(date, psavert, uempmed) %>% gather(key = "variable", value = "value", -date) %>% as.data.table() # Define UI for application that draws a histogram ui <- fluidPage( # Application title titlePanel("Football Analysis"), sidebarLayout( sidebarPanel( selectizeInput("variable_names", "Names of Variable", choices = unique(df$variable), selected = unique(df$variable)[1]) ), mainPanel( highchartOutput("plot") ) ) ) server <- function(input, output) { reactivedf <- reactive({ df[variable == input$variable_names,] }) output$plot <- renderHighchart({ df %>% hchart('line',hcaes(x = reactivedf()$date,y = reactivedf()$value)) }) } # Run the application shinyApp(ui = ui, server = server)
我的目标只是想选择一种类型的序列
ggplot(df, aes(x = date, y = value)) +
geom_line(aes(color = variable), size = 1) +
scale_color_manual(values = c("#00AFBB", "#E7B800")) +
theme_minimal()
