setContinuousColorScale: Continuous color scale

In scatterPlotMatrix: `htmlwidget` for a Scatter Plot Matrix

Continuous color scale

Description

Tells which color scale to use when the Z axis is set to a continuous column.

Usage

setContinuousColorScale(id, continuousCsId)

Arguments

id	Output variable to read from (id which references the requested plot).
continuousCsId	One of the available color scale ids (Viridis, Inferno, Magma, Plasma, Warm, Cool, Rainbow, CubehelixDefault, Blues, Greens, Greys, Oranges, Purples, Reds, BuGn, BuPu, GnBu, OrRd, PuBuGn, PuBu, PuRd, RdBu, RdPu, YlGnBu, YlGn, YlOrBr, YlOrRd).

Value

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

Examples

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

   ui <- fluidPage(
     selectInput(
       "continuousCsSelect",
       "Continuous Color Scale:",
