我试图用fill和NA值绘制一个折线图.Plotly自动用NA值填充零件，我希望它为空.获得正确图形的最佳方法是什么？
不能将NA值设置为0.我也在使用胡佛，不希望在悬停在线上时得到0的结果.
示例R数据+代码:
library(plotly)
set.seed(1)
A = data.frame(x = 1900:2000, value=cumsum(rnorm(101)))
A[40:70, 2:3] = NA
fig <- plot_ly(x = A$x, y = A$value, type = 'scatter', mode = 'lines', fill = 'tozeroy')
fig
Result:
Desired Result:
您可以将数据放入单独的记录道中，以实现以下目的:
library(plotly)
library(data.table)
set.seed(1)
A = data.frame(x = 1900:2000, value = cumsum(rnorm(101)))
A[40:70, 2] = NA
setDT(A)
A[, id := rleid(is.na(value))]
fig <- plot_ly(
data = A,
x = ~ x,
y = ~ value,
type = 'scatter',
mode = 'lines',
fill = 'tozeroy',
split = ~ id,
color = I("#1f77b4"),
showlegend = FALSE
)
fig
