Tokens aesthetics mapping

Tokens aesthetics mapping

token_aes(
  size = token_scale(),
  color = token_scale(),
  image = token_scale(),
  opacity = token_scale(),
  shape = "circle",
  attributes = list()
)

Arguments

size

The scale used for the token size.

color

The scale used for the token color,

image

The scale used for the token image.

opacity

The scale used for the token opacity.

shape

The (fixed) SVG shape to be used to draw tokens. Can be either 'circle' (default), 'rect' or 'image'. In the latter case the image URL needs to be specified as parameter 'token_image'.

attributes

A list of additional (fixed) SVG attributes to be added to each token.

Value

An aesthetics mapping for `animate_process`.

Examples

data(example_log)

# Change default token sizes / shape
animate_process(example_log, mapping = token_aes(size = token_scale(12), shape = "rect"))

# \donttest{
# Change default token color
animate_process(example_log, mapping = token_aes(color = token_scale("red")))


# Change default token opacity
animate_process(example_log, mapping = token_aes(opacity = token_scale("0.2")))


# Change default token image (GIFs work too)
animate_process(example_log,
   mapping = token_aes(shape = "image",
    size = token_scale(10),
    image = token_scale("https://upload.wikimedia.org/wikipedia/commons/5/5f/Pacman.gif")))


# A more elaborate example with a secondary data frame
library(eventdataR)
data(traffic_fines)
# Change token color based on a numeric attribute, here the nonsensical 'time' of an event
animate_process(edeaR::filter_trace_frequency(bupaR::sample_n(traffic_fines,1000),percentage=0.95),
  legend = "color", mode = "relative",
  mapping = token_aes(color = token_scale("amount",
                                          scale = "linear",
                                          range = c("yellow","red"))))
