Each line a different color using `dataset` option

[helgasoft]

By using a dataset, you are setting a single long line that goes back and forth between Values and Summary.
This line can have a single color.
Here is how to set individual lines which are later easily colored with a palette.

set.seed(222)
.data = tibble::tibble(Values = rnorm(10), Summary = .5)
d <- tidyr::pivot_longer(.data, cols = c(Values, Summary), names_to = "x", values_to = "y")
palet <- c(
      "#9E0142",
      "#D53E4F",
      "#F46D43",
      "#FDAE61",
      "#FEE08B",
      "#E6F598",
      "#ABDDA4",
      "#66C2A5",
      "#3288BD",
      "#5E4FA2")
# set lines with just 2(from-to) points 
series <- list()
for(i in seq(1, nrow(d), by=2)) {
	tmp <- list( 
		type= 'line',
		data= list(list(d[i,  ]$x, d[i,  ]$y), 
	                   list(d[i+1,]$x, d[i+1,]$y))
	)
	series <- append(series, list(tmp))
}
echarty::ec.init(
	color= palet, height= "250px",
	xAxis= list(type='category'),
	series= series
)

Ahh, thank you @helgasoft!
That's the ticket!
