有没有办法让plotly在多行上显示悬停文本/让它识别文本中的特殊字符行''?
我想做的一个虚拟版本是:
data <- data.frame(cbind(rnorm(10, 8), rnorm(10, 2)))
names(data)<-c("thing1", "thing2")
data$hovertext <- paste("here's a coordinate: ",
round(data$thing1,1), sep = "n")
p <- plot_ly(data, type = 'scatter', x = thing1, y = thing2,
text = hovertext, hoverinfo = 'text', mode = "markers")
当然,这只是忽略分隔符并在一行上打印所有内容。我可以欺骗 plotly/R 识别该换行符吗?
只需使用 HTML 标记<br>
:
library(plotly)
data <- data.frame(cbind(rnorm(10, 8), rnorm(10, 2)))
names(data) <- c("thing1", "thing2")
data$hovertext <- paste("here's a coordinate:",
round(data$thing1,1), sep = "<br>")
p <- plot_ly(data, type = 'scatter', x = ~thing1, y = ~thing2,
text = ~hovertext, hoverinfo = 'text', mode = "markers")
此外,您还可以使用 HTML 标签来更改字体样式(以及更多)......
