Add on-graph labels to graphs

Source: R/plot_label.R
plot_label.Rd

Add text labels for lines, columns or other elements directly onto the graph plot. This is preferred over using legends.

Usage

plot_label(
  label,
  x,
  y,
  colour = NA,
  size = 3.5,
  hjust = 0,
  geom = c("text", "label"),
  angle = 0,
  facet_name = NULL,
  facet_value = NULL
)

plab(
  label,
  x,
  y,
  colour = NA,
  size = 3.5,
  hjust = 0,
  geom = c("text", "label"),
  angle = 0,
  facet_name = NULL,
  facet_value = NULL
)

Arguments

label

String vector. Label text to be displayed.

x

Numeric or string vector. X-axis positions of the label text.

y

Numeric or string vector. Y-axis positions of the label text.

colour

(optional) Vector of colour names or strings. Default uses the e61 palette.

size

(optional) Integer. Size of the text, the default size should be appropriate in most cases.

hjust

(optional) A numeric value from 0-1. Adjusts the alignment of the text. 0 left-aligns (default), 0.5 centre-aligns and 1 right-aligns.

geom

(optional) String. Either "text" (default) or "label". "label" adds a white box around the text which could be useful sometimes.

angle

(optional) Numeric. Rotate the labels. Defaults to 0 which is normal left-to-right text.

facet_name, facet_value

(optional) String. Specify the name of the facetting variable in facet_name and the panel to show the labels in using facet_value. Defaults to NULL which shows the labels on all facets. You must specify both facet_name and facet_value or leave both as NULL.
