我正在尝试使用calendar
软件包制作echarts4r
。
library(tidyverse)
library(echarts4r)
dates <- seq.Date(as.Date("2017-01-01"), as.Date("2018-12-31"), by = "day")
values <- rnorm(length(dates), 20, 6)
year <- data.frame(date = dates, values = values)
year %>%
e_charts(date) %>%
e_calendar(range = "2017",top="40") %>%
e_calendar(range = "2018",top="260") %>%
e_heatmap(values, coord.system = "calendar") %>%
e_visual_map(max = 30) %>%
e_title("Calendar", "Heatmap")%>%
e_tooltip("item")
但是这一年并没有策划2018年。
如何在calendar
中设置自动分隔的年份?
是fill
中的ggplot
之类的解决方案吗?

该API笨拙且不直观,但确实可行。您需要像现在一样添加两个日历,并在e_heatmap
函数中引用它们的索引(以便根据正确的日历绘制热图)。另外,我使用e_data
来传递第二个日历的值(x
)。确保调整日历的位置,以使其不重叠(即:top = 300
)。
dates18 <- seq.Date(as.Date("2018-01-01"), as.Date("2018-12-31"), by = "day")
dates17 <- seq.Date(as.Date("2017-01-01"), as.Date("2017-12-31"), by = "day")
values <- rnorm(length(dates18), 20, 6)
df <- data.frame(date18 = dates18, date17 = dates17, values = values)
df %>%
e_charts(date18) %>%
e_calendar(range = "2018") %>%
e_heatmap(values, coord.system = "calendar", calendarIndex = 0, name = "2018") %>%
e_data(df, date17) %>%
e_calendar(range = "2017", top = 300) %>%
e_heatmap(values, coord.system = "calendar", calendarIndex = 1, name = "2017") %>%
e_visual_map(max = 30)
更新
从0.2.0
版本开始,可以通过按年份对数据进行分组来完成上述操作,这更加清晰和容易:
dates <- seq.Date(as.Date("2017-01-01"), as.Date("2018-12-31"), by = "day")
values <- rnorm(length(dates), 20, 6)
year <- data.frame(date = dates, values = values)
year %>%
dplyr::mutate(year = format(date, "%Y")) %>% # get year from date
group_by(year) %>%
e_charts(date) %>%
e_calendar(range = "2017",top="40") %>%
e_calendar(range = "2018",top="260") %>%
e_heatmap(values, coord_system = "calendar") %>%
e_visual_map(max = 30) %>%
e_title("Calendar", "Heatmap")%>%
e_tooltip("item")
