Question

问题：

我的gvisMotionChart在暂停时工作正常，但在动画时为空。

代码：

Motion=gvisMotionChart(mydat,
                       idvar="Time_Period_Year_Cd",
                       timevar="Year",
                       xvar="Total_Customers",
                       yvar="Percent_Happy",
                       colorvar = "New_Product_Count",
                       sizevar = "Group_A_Count"
)
plot(Motion)

结果（暂停时）：

结果（动画时）：

我认为它必须是我的代码或数据的东西，因为我能够让文档中的示例正常工作。我尝试了几种变体，比如没有指定xvar然后将“年”绘制为x轴等等。

数据：

mydat <- structure(list(Time_Period_Year_Cd = c(201220L, 201320L, 201340L,

Answer 1

每个idvar值只有一个timevar值：

mydat %>% count(Time_Period_Year_Cd) %>% head
#   Time_Period_Year_Cd     n
#                 <int> <int>
# 1              201220     1
# 2              201320     1
# 3              201340     1
# 4              201360     1
# 5              201420     1
# 6              201440     1

所以不可能有任何过渡。与例如相反。

df <- mydat %>% mutate(idvar = substr(Time_Period_Year_Cd, 1, 4)) %>% group_by(idvar) %>% mutate(timevar = 1:n()) %>% ungroup
Motion=gvisMotionChart(df,
                       idvar="idvar",
                       timevar="timevar",
                       xvar="Total_Customers",
                       yvar="Percent_Happy",
                       colorvar = "New_Product_Count",
                       sizevar = "Group_A_Count"
)
plot(Motion)

动画时gvisMotionChart为空白
