e_highlight echarts4r package

[parth77]

Hi Friends, I wanted to highlight a certain section of a line based on its y/x axis value.
This is using echarts4r package, because I want the interactivity of the plot.

Thank you in advance for the help!

Below is an example that adds a new variable (y1) to the data set that meets a specific condition (< 40 in this case). The new variable is then referenced in a second e_line().

library(echarts4r)
library(dplyr)
set.seed(123)

df = data.frame(x = seq(50),
                y = sample(10:60, 50, replace = T)
                ) |>
  mutate(y1 = ifelse(y < 40, y, NA))

df |>
  e_charts(x) |>
  e_line(y) |>
  e_line(y1)

Thank again @scottyd22 for a quick and robust solution.
So we simply overlap the original geometry with another geometry.
