Item distribution chart, ggplot2 equivalent of the dashboard/studio panel

Source: R/plots.R
sframe_plot_item_chart.Rd

Shared by launch_dashboard() (inst/shiny/dashboard/app.R) and the SurveyStudio dashboard tab (inst/shiny/app.R), which otherwise duplicated this base-graphics chart. Callers fall back to their own base graphics when this returns NULL (ggplot2 not installed, unsupported item type, or no data), so the dashboard keeps working without ggplot2.

Usage

sframe_plot_item_chart(
  item,
  col_data,
  choice_set = NULL,
  palette = c("web", "print")
)

Arguments

item

A list with at least type and label (an sframe item).

col_data

The response column for this item.

choice_set

A list with values and labels (an sframe choice set), or NULL if the item has none.

palette

One of "web" or "print". See sframe_brand().

Value

A ggplot2 object, or NULL if this item type/data is unsupported.
