R：消失的图表

Question

我正在使用 R 编程语言。使用以下代码，我制作了这些交互式时间序列图：

library(dplyr)
library(ggplot2)
library(shiny)
library(plotly)
library(htmltools)

library(dplyr)
#generate data
set.seed(123)

######

var = rnorm(731, 85,25)
date= seq(as.Date("2014/1/1"), as.Date("2016/1/1"),by="day")
data = data.frame(var,date)

vals <- 90:100
combine <- vector('list', length(vals))
count <- 0
for (i in vals) {
    
    data$var_i = i
    data$new_var_i = ifelse(data$var >i,1,0)
    
    #percent of observations greater than i (each month)
    aggregate_i = data %>%
        mutate(date = as.Date(date)) %>%
        group_by(month = format(date, "%Y-%m")) %>%
        summarise( mean = mean(new_var_i))
    
    #combine files together
    
    aggregate_i$var = i
    aggregate_i$var = as.factor(aggregate_i$var)
    
    count <- count + 1
    combine[[count]] <- aggregate_i
    
}


result_2 <- bind_rows(combine)
result_2$group = "group_b"
result_2$group = as.factor(result_2$group)

a = result_2 %>%
  plot_ly(x=~month, y=~mean, color=~group) %>%
  group_by(group) %>%
  add_lines(frame=~var,hoverinfo = "text",
            text = ~ paste0("Month: ",month, "<br>",
                            "Mean: ", mean, "<br>",
                            "Total: ", mean(mean))) %>%
  layout(title = list(text = "title"),
         xaxis = list(tickangle = -90, tickformat = "%m-%Y"))

#view plots

a

b

当您单独查看这两个图表时，它们可以正常工作：

但是当我尝试使用plotly::subplot() 命令时，第二张图消失了：

subplot(a,b, nrows=1)

有谁知道为什么会这样，有没有办法解决这个问题？还有一种方法可以在这种情况下使用ggplot2::facet_wrap() 命令将两个图“同步”在一起（例如：R: "tie" two graphs together）？

谢谢

Answer 1

您的框架轴不会在任何点相交，因此您不会期望同时看到两个图表试试这个并按下播放，您将看到过渡。

subplot(b,a) %>%
  animation_opts(frame = 300, transition = 100, easing="elastic") %>%
  animation_slider(currentvalue = list(prefix=NULL, font=list(color="red", size=40)))

当帧号进入其帧范围时，每个图表都会出现。
