如何在R highcharter包中设置dataLabel格式和轴标签角度

Question

我正在尝试使用R highcharter包来创建条形图功能.代码如下.我请求帮助1 - 如何将dataLabels的格式更改为百分比？2 - 如何设置X轴标签显示角度.我想把它设置为45度

hcbar_categorycount_vertical <- function(data=x,var=y){
df <- data.frame(prop.table(table(data[var])))
names(df) <- c(var,'Proportion')
df$Proportion <- round(df$Proportion*100,2)
df <- df%>% arrange(-Proportion)
df[,1] <- as.character(df[,1])
df[,1] <- factor(df[,1], levels = df[,1])
df$Cumulative <- round(cumsum(df$Proportion),2)

highchart(debug = TRUE) %>%
hc_xAxis(categories=df[[1]]) %>%
hc_yAxis(labels = list(format = "{value}%"), max = 100) %>%
hc_add_series(name=var,data=df$Proportion,type = "column",dataLabels =       list(enabled = TRUE, format='{point.label}%'))
}

我不确定dataLabel属性列表中"format"的语法应该是什么.上面的代码似乎不起作用.我已经提到了highcharter vignette和这个网站:http://jkunst.com/highcharter/highcharts-api.html#hc_xaxis-and-hc_yaxis

但找不到答案.我在这里先向您的帮助表示感谢.

Answer 1

@ jeganathan-velu,

1)尝试的改变'{point.label}%'通过'{point.y}%'

2)参见highcharts 示例.您需要添加hc_xAxis参数labels = list(rotation = 90)

highcharter包只是highcharts的包装器,因此您可以从highcharts 检查所有示例和记录良好的API.复制highcharts演示

Answer 2

经过反复试验和进一步研究后找到了答案http://api.highcharts.com/highcharts#xAxis.labels.rotation

发布更新的代码组件以造福他人。

hc_xAxis(categories=df[[1]],labels = list(rotation=-45)) %>%
hc_yAxis(labels = list(format = "{value}%"), max = 100) %>%
hc_add_series(name=var,data=df$Proportion,type = "column",dataLabels = list(enabled = TRUE, format='{point.y}%'))
