The canvas a chart is drawn on — chart_canvas

The size asked for, each side that was not asked for taken from MAIDR_CHART_SIZE, or from MAIDR_CANDLESTICK_SIZE for a candlestick chart. A candlestick chart smaller than MAIDR_CANDLESTICK_SIZE on either side is drawn at that size on that side instead. When that size was asked for, a message (of class maidr_chart_size_message) names the size it is drawn at: a size asked for is never changed silently. One that was not – a knitted document's figure size, which every chunk that sets none is drawn at – is enlarged without a word, as before maidr read a chunk's size. A Base R chart too small for a size no one asked for is enlarged too, and says so (base_r_page_that_fits()).

Usage

chart_canvas_size(
  width = NULL,
  height = NULL,
  candlestick = FALSE,
  asked = !is.null(width) || !is.null(height)
)

Arguments

width, height: The size in inches, or NULL for none. Checked by the caller, with check_chart_size().
candlestick: Whether the chart holds a candlestick layer.
asked: Whether width and height were asked for: by default when either is given. A knitted chunk's are asked for only when they are not the document's own (knitr_chart_size()).

Value

A named numeric vector, width and height, in inches.
