Basics

library(peity)

peity("1/5", type = "pie")

# pass options as list
peity(c(1,5), type = "donut", options = list(fill = I(c("green", "red")), radius = 100))
peity(c(1,5), type = "donut", options = list(fill = c("#845422", "#ead61c"), radius = 50, innerRadius = 40))
peity(rnorm(50, 2, 1), type = "line", options = list(width = 100))
peity(c(1,5,3), type = "bar", options = list(fill = I("green")))

Set colors dynamically

peity(c(4,-2,3, -4), type = "bar", options = list(fill = htmlwidgets::JS('function(value) {
    return value > 0 ? "green" : "red"
}')))
  
js_fun <- htmlwidgets::JS('function(_, i, all) {
    var g = parseInt((i / all.length) * 255)
    return "rgb(255, " + g + ", 0)"
}')

peity(c(0,-3,-6,-4,-5,-4,-7,-3,-5,-2), type = "bar", options = list(fill = js_fun))
