[英]ggplot, nested X-Axis for interaction() factor variables in bar plot
[英]ggplot missing plot with x-axis factor
以下工作正常:
my_df <- data.frame(x_val = 1:10, y_val = sample(1:20,10),
labels = sample(c("a", "b"), 10, replace = T))
ggplot(data = my_df, aes(x = x_val, y = y_val)) + geom_line()
但如果我有機會x_val
進行因子分析,我會得到空白圖和消息:
my_df <- data.frame(x_val = 1:10, y_val = sample(1:20,10),
labels = sample(c("a", "b"), 10, replace = T))
my_df$x_val <- as.factor(my_df$x_val)
ggplot(data = my_df, aes(x = x_val, y = y_val)) + geom_line()
信息:
geom_path: Each group consists of only one observation. Do you
need to adjust the group aesthetic?
我顯然可以放棄factor
轉換,但我需要它來用scale_x_discrete(breaks = 1:10,labels= my_df$labels)
替換 x 軸的scale_x_discrete(breaks = 1:10,labels= my_df$labels)
。 這是我借用的鏈接
有什么想法嗎?
您可以將x_val
為數字並使用scale_x_continuous(breaks = 1:10,labels= my_df$labels)
代替嗎?
