R绘制的动画图表仅显示在初始帧中具有数据的组

问题描述

我正在尝试使用R中的plotly创建动画气泡图，并且遇到了一个特别困难的问题.

I'm trying to create an animated bubble chart using plotly in R, and I've run into a particularly difficult issue.

library(plotly)
dates <- 2000:2010
countries <- c("US", "GB", "JP")
df <- merge(dates, countries, all=TRUE)
names(df) <- c("Date", "Country")


df$x <- rnorm(nrow(df))
df$y <- rnorm(nrow(df))

df[1:3, c("x", "y")] <- NA

p <- plot_ly(df, x=~x, y=~y, color=~Country, frame=~Date, type="scatter", mode="markers")
p

由于美国前3年缺少值，因此即使在美国有数据的年份中，得出的图也根本不包含美国的点.

Due to the missing values for the US' first 3 years, the resulting plot doesn't include the US' dot at all, even for the years where the US has data.

结果图表的截屏

推荐答案

我不知道如何使用plotly对其进行修复，但是如果您对ggplotly没问题，那么似乎可以完成此任务:

I don't know how to fix it with plotly but if you are ok with ggplotly it seems to do the job:

p <- ggplot(df, aes(x, y, color = Country)) +
  geom_point(aes(frame = Date)) + theme_bw()

ggplotly(p)
