setCategoricalColorScale {parallelPlot}

Lines colors

Description

Tells which color scale to use when reference column is of type categorical.

Usage

setCategoricalColorScale(id, categoricalCsId)

Arguments

id

output variable to read from (id which references the requested plot)

categoricalCsId

one of the available color scale ids

Details

If a column is defined as the reference (for example by clicking on its header), a color scale is associated to this column. Available color scale ids are: Category10, Accent, Dark2, Paired, Set1.

Value

No return value, called from shiny applications for side effects.

Examples

 if(interactive() && require(shiny)) {
   library(shiny)
   library(parallelPlot)

   ui <- fluidPage(
     selectInput("categoricalCsSelect", "Categorical Color Scale:",
       choices = list(
         "Category10" = "Category10", "Accent" = "Accent", "Dark2" = "Dark2",
         "Paired" = "Paired", "Set1" = "Set1"
       ),
       selected = "Category10"
     ),
     p("Selector controls used colors when reference column is of type categorical"),
     parallelPlotOutput("parPlot")
   )

   server <- function(input, output, session) {
     output$parPlot <- renderParallelPlot({
       parallelPlot(data = iris, refColumnDim = "Species")
     })
     observeEvent(input$categoricalCsSelect, {
       parallelPlot::setCategoricalColorScale("parPlot", input$categoricalCsSelect)
     })
   }

   shinyApp(ui, server)
