Hi alll, i do not understand how the invocation of a control element to refresh a chart works. I'm sorry I can find nothing at all in the internet about this topic, however I do not know what keywords to google...
A slider invokes the refresh of my chart after changing it. the checkbox does not. But how does it work? I mean, I have no action=renderLineChart() ore something on my slider but it works, the checkbox does not refresh the chart. How does the slider know what to do? And how can i tell a control-element what to do? I apreciate any hint!
I am using this as a template:
https://shiny.rstudio.com/gallery/nvd3-line-chart-output.html
server.r
function(input, output, session) {
#some code to load data
output$mychart <- renderLineChart({
#....some more code
return_my_dataframe
})
}
ui.r
library(shiny)
library(shinydashboard)
library(shinyWidgets)
shinyUI(
dashboardPage(
dashboardHeader(title = "My Dashboard"),
dashboardSidebar(
sidebarMenu(
menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
menuItem("Info", tabName = "info", icon = icon("info"))
)
),
dashboardBody(
tabItems(
tabItem(tabName = "dashboard",
h2("Dashboard tab content"),
fluidRow(
box(title = "title1", status = "primary", width=12,
column(width=12,
lineChartOutput("mychart")
)
)
),
fluidRow(
box(title = "Factor", status = "primary", width=3,
column(width=12,
sliderInput("factor", "(y * 0.001 bis 0.02)", 0.001, 0.02, 0.02, step=0.001,
animate=animationOptions(interval=500, loop=TRUE)),
sliderInput("epoche", "move (in years)", 0, 10, 0, step=1,
animate=animationOptions(interval=500, loop=TRUE))
)
),
box(title = "Concat Curves", status = "primary", width=3,
column(width=12,
awesomeCheckboxGroup(
inputId = "checkgroup2",
label = "Click me!",
choices = c("1", "2", "ALL"),
status = "info"
)
)
)
)
),
tabItem(tabName = "info",
h2("Info"),
fluidRow(
column(width=8,
h3("Title"),
p("Move slider...")
)
)
)
)
)
)
)
