@bpfaff, thank you for pointing out the error in EChart's new violin chart. We opened an issue in their repo.
The echarty violin chart has no problem with negative values:
do.call(ec.init, ec$violin(PlantGrowth_NegativeValues, cname='group', cvalue='weight', jitter=0.1))

do.call(ec.init, ec$violin(warpbreaks, cname='wool', cvalue='breaks', jitter=0, j.itemStyle= list(color='chartreuse'), m.symbolSize=8)) |> ec.theme('dark-mushroom')

@mdneuzerling, here is how to draw series with disparate data sets with echarty.

dat1 <- seq.Date(from = as.Date("2023-01-01"), by= 2, length.out = 100)
dat2 <- seq.Date(from = as.Date("2023-01-02"), by= 2, length.out = 100)
d1 <- data.frame(date= dat1, value= cumsum(rnorm(100, mean = 0.5, sd= 2)) + 50)
d2 <- data.frame(date= dat2, value= cumsum(rnorm(100, mean = 0.4, sd= 2)) + 30)
ec.init(
  dataset= list(
    list(source= ec.data(d1)),
    list(source= ec.data(d2))
  ),
  series= list(
    list(type='line', name='s1', datasetIndex=1, showSymbol=F), 
    list(type='line', name='s2', datasetIndex=2, showSymbol=F)
  ),
  xAxis= list(type='time'), legend= list(top=11), tooltip= list(trigger= 'axis'), dataZoom= list(show=T)
)
