library(recharts)

1 介绍Introduction

缩放漫游默认放置于6点钟位。

建议用chart %>% setDataZoom(...)格式调用setDataZoom.

2 用法Function Call

所有函数名都有小驼峰法和小写连划线(Hadly Wickham推荐此法)两种形式。为了便于偷懒，还有缩写版（如dataZoom缩写成dz）。

setDataZoom(chart, show = TRUE, pos = 6, range = NULL, width = 30,
  fill = "rgba(144,197,237,0.2)", handle = "rgba(70,130,180,0.8)",
  bgColor = "rgba(0,0,0,0)", dataBgColor = "#eee", showDetail = TRUE,
  realtime = FALSE, zoomLock = FALSE, ...)

set_datazoom(chart, show = TRUE, pos = 6, range = NULL, width = 30,
  fill = "rgba(144,197,237,0.2)", handle = "rgba(70,130,180,0.8)",
  bgColor = "rgba(0,0,0,0)", dataBgColor = "#eee", showDetail = TRUE,
  realtime = FALSE, zoomLock = FALSE, ...)

set_dz(chart, show = TRUE, pos = 6, range = NULL, width = 30,
  fill = "rgba(144,197,237,0.2)", handle = "rgba(70,130,180,0.8)",
  bgColor = "rgba(0,0,0,0)", dataBgColor = "#eee", showDetail = TRUE,
  realtime = FALSE, zoomLock = FALSE, ...)

setDZ(chart, show = TRUE, pos = 6, range = NULL, width = 30,
  fill = "rgba(144,197,237,0.2)", handle = "rgba(70,130,180,0.8)",
  bgColor = "rgba(0,0,0,0)", dataBgColor = "#eee", showDetail = TRUE,
  realtime = FALSE, zoomLock = FALSE, ...)

参数	要求
chart	echartR或echart创建的Echarts对象.
show	逻辑型，是否显示缩放漫游。默认为FALSE。如要把缩放漫游部件整体从Echarts对象中移除，设为NULL.
pos	缩放漫游的时钟方位，默认为6，参见vecPos。也可以自定义方位向量c(x, y, orient).
range	向量c(min, max). 不能超出区间c(0, 100)
width	缩放漫游宽度，默认为20px.
fill	缩放漫游控制轴颜色，格式为’rgba(red, green, blue, alpha)’，默认为'rgba(144,197,237,0.2)' (“#90C5ED33”).
handle	缩放漫游手柄颜色，格式为’rgba(red, green, blue, alpha)’，默认为'rgba(70,130,180,0.8)' (“#4682B4CC”).
bgColor	背景色，默认为透明(‘rgba(0,0,0,0)’).
dataBgColor	数据剪影的背景色 (只显示第一个系列). 默认为 ‘#eee’.
showDetail	逻辑型，缩放时是否显示明细。默认为TRUE.
realtime	逻辑型，缩放时是否实时显示明细，默认为FALSE.
zoomLock	逻辑型，是否锁定缩放区间。默认为FALSE.
…	省略号

3 举例Showcase

g <- echartr(iris, Sepal.Width, Petal.Width, Species)
g

初始时不显示缩放漫游，可以打开。

g %>% setDataZoom(show=TRUE)

移动缩放漫游。

g %>% setDataZoom(pos=12)

自定义格式。

g %>% setDataZoom(bgColor='yellow', dataBgColor='gold', fill='tan',
                  handle='maroon')

初始选中20% - 60%.

g %>% setDataZoom(range=c(20, 60))
