Function to plot a control chart.

Description

Function to plot a control chart.

Usage

plot_control_chart(
  df,
  by = as.character(),
  size = 2,
  control_constant = 1.128,
  control_multiplier = 3,
  add_reference = FALSE,
  scales = "fixed"
)

Arguments

df	Input data frame containing value and date variables.
by	A character vector indicating the grouping variables within df to calculate control limits for and plot as facets.
size	Size of the plots' points.
control_constant	Constant used to transform the mean delta to sequential deviation. Through simulations, this is usually set as 1.128
control_multiplier	Multiplier for sequential deviation to get the lower and upper control limits, typically 3.
add_reference	Should a reference value be added to the plot? This value must be called value_reference in df.
scales	A ggplot2 argument for setting the scales of the facets.

Value

ggplot2 plot.
