Add a Parameter Slider (Shiny Only)

Adds a slider control below the chart. Read its Shiny input in the render expression and pass the value to the transform option to recompute the chart.

Usage

setSlider(myIO, param, label, min, max, value, step = NULL, debounce = 200)

Arguments

myIO: an htmlwidget object created by the myIO() function
param: Slider input name (e.g., "ci_level", "degree"). Values are sent to input$`myIO-{outputId}-slider-{param}`.
label: display label for the slider
min: minimum value
max: maximum value
value: default value
step: step size (default: NULL for auto)
debounce: debounce delay in milliseconds (default: 200)

Value

A modified myIO htmlwidget with slider config attached.

Examples

if (FALSE) { # \dontrun{
# In a Shiny server function:
output$chart <- renderMyIO({
  level <- input$`myIO-chart-slider-ci_level`
  if (is.null(level)) level <- 0.95
  myIO(data = mtcars) |>
    addIoLayer(
      type = "regression", label = "fit",
      mapping = list(x_var = "wt", y_var = "mpg"),
      options = list(level = level)
    ) |>
    setSlider("ci_level", "Confidence level", 0.80, 0.99, level, 0.01)
})
} # }
