图表中的线型如何与图例匹配？

library(echarts4r)

df <- data.frame(
  x = seq(50),
  y = rnorm(50, 10, 3),
  z = rnorm(50, 10, 3)
)

df %>% 
  e_charts(x) %>% 
  e_line(y, showSymbol = FALSE, lineStyle = list(type = "dashed")) %>%
  e_line(z, showSymbol = FALSE, lineStyle = list(type = "dotted"))

字符串
在输出中，图例显示带有圆圈的线-如果它显示实际的线类型会更好，或者至少没有圆圈，例如：-- y，- z
