现在，我必须在同一张图上绘制两个时间序列. 我知道

Now I have to plot both timeseries on the same graph. I know

plot_ly(y=betas$historical_beta)

但是如何添加多个y轴?

but how to add multiple y-axis?

推荐答案

这是您想要的吗?

df1 = stack(betas)
plot_ly(df1,y=values,group=ind)
p

或

p <- plot_ly(betas,y=historical_beta)
p <- add_trace(p,y=implied_beta)
p

或者如果您确实要说2个y轴:

or in case you really meant 2 y axes:

ay <- list(
  tickfont = list(color = "red"),
  overlaying = "y",
  side = "right"
)
p <- plot_ly(betas,y=historical_beta,name="Historical Beta") %>%
       add_trace(y=implied_beta,name="Implied Beta",yaxis="y2") %>%
       layout(yaxis2=ay)
p

第一个在自动标记迹线方面做得更好.

The first one does a nicer job of automatically labeling the traces.
