R - ggvis - 我如何標記多個平滑數據組

我有一個數據幀，其中包含時間和鍵值對，我想按鍵分組，然後爲每個數據組呈現一條平滑線。然後我想按鍵來標記它。我可以做所有，但基於密鑰獲取標籤。我無法看到在文檔中設置此位置。R - ggvis - 我如何標記多個平滑數據組

請發表您的數據。例如，我們不能做任何事情截圖。 – mtoto

更新了數據 –

你可以在這裏得到dput（）的輸出[link]（https://onedrive.live.com/redir?resid=9DC28E4A63FAF571!5465&authkey=!ACXQVt-6MoXPUL8&ithint=file%2cout） –

你可以嘗試添加stroke參數layer_smooths將由您的分組的顏色他們，同時也將增加一個傳說：

df %>% ggvis(~time, ~newval) %>% 
    group_by(newcol) %>% 
    layer_smooths(stroke=~newcol) %>% 
    add_axis("x", properties = axis_props(
     axis = list(stroke = "black", strokeWidth = 2), 
     grid = list(stroke = "black"), 
     ticks = list(stroke = "black", strokeWidth = 2), 
     labels = list(angle = 45, align = "left", fontSize = 10) 
    ))

生產：

如果你希望每個標記線，您可以創建一個文本標籤一個小的數據幀和渲染，作爲一個附加的layer_text。

label_df <- df %>% group_by(newcol) %>% sample_n(1) 

df %>% ggvis(~time, ~newval) %>% 
    group_by(newcol) %>% 
    layer_smooths(stroke=~newcol) %>% 
    layer_text(data=label_df, 
       text:=~newcol, 
       baseline:="middle", fontSize:=8) %>% 
    add_axis("x", properties = axis_props(
     axis = list(stroke = "black", strokeWidth = 2), 
     grid = list(stroke = "black"), 
     ticks = list(stroke = "black", strokeWidth = 2), 
     labels = list(angle = 45, align = "left", fontSize = 10) 
    ))
