我想在一个循环中绘制多条轨迹而不覆盖所有以前的轨迹。
在2015 年的这篇文章evaluate = TRUE
中,通过在 plot_ly 或 add_trace 函数中进行设置,提出了在循环中添加跟踪的解决方案。但是,截至 2017 年,在较新版本的 plot_ly 中,evaluate
它不是一个属性。
'scatter3d' objects don't have these attributes: 'evaluate'
这个问题,这个问题也回答不了问题。这篇文章承认 evaluate = TRUE 不适用于 new plotly,但没有给出解决方案。这个问题的新解决方案是什么?

我的代码:
library(plotly)
p <- plot_ly(temp, type = 'scatter3d', mode = 'lines', width = 1)
for(i in 1:3){
x = paste0("x_",i)
y = paste0("y_",i)
z = paste0("z_",i)
p <- add_trace(p, x = ~get(x), y = ~get(y), z = ~get(z))
}
p
