如何更改取決於變量的高字符列圖的調色板顏色？

Question

我開始在R中使用highcharter程序包（版本0.5.0），但我無法弄清楚如何更改列的顏色，這些列鏈接到系列美學中的變量上。 數據框的開頭如下所示：

> head(Top_G)
# A tibble: 6 × 29
     Rk              Name   Yrs  From    To   ASG     G    PA    AB     R     H   X2B   X3B    HR   RBI
  <int>             <chr> <int> <int> <int> <int> <int> <int> <int> <int> <int> <int> <int> <int> <int>
1   352      Omar Vizquel    24  1989  2012     3  2968 12013 10586  1445  2877   456    77    80   951
2    14 Luis Aparicio HOF    18  1956  1973    13  2599 11230 10230  1335  2677   394    92    83   791
3    75   Dave Concepcion    19  1970  1988     9  2488  9641  8723   993  2326   389    48   101   950
4     1       Bobby Abreu    18  1996  2014     2  2425 10081  8480  1453  2470   574    59   288  1363
5   107  Andres Galarraga    19  1985  2004     5  2257  8916  8096  1195  2333   444    32   399  1425
6    43    Miguel Cabrera    14  2003  2016    11  2096  9001  7853  1321  2519   523    17   446  1553
# ... with 14 more variables: SB <int>, CS <int>, BB <int>, SO <int>, BA <dbl>, OBP <dbl>, SLG <dbl>,
#   OPS <dbl>, Birthdate <date>, Debut <date>, City <chr>, State <chr>, Pos <chr>, Active <chr>

Active變量有兩個可能的值，這是我用來關聯圖表中color美學的值。 我使用的代碼如下：

highchart() %>%
  hc_add_series(Top_G, "column", hcaes(x = Name, y = G, color = Active), name = "G", showInLegend = FALSE) %>%
  hc_colors(cols) %>%
  #hc_add_series(Top_Yrs, name = "Games") %>%
  hc_add_theme(hc_theme_smpl()) %>%
  hc_title(text = "Games", style = list(fontSize = "22px")) %>%
  hc_subtitle(text = "Chart", style = list(fontSize = "12px")) %>%
  hc_yAxis(title = list(text = "G")) %>%
  hc_xAxis(categories = Top_G$Name) %>%
  hc_xAxis(title = list(text = "Player")) %>%
  hc_credits(enabled = TRUE, # add credits
             text = "Test") %>%
  hc_tooltip(crosshairs = FALSE, backgroundColor = "#DDDEE6",
             shared = FALSE, borderWidth = 2)

但是該圖使用默認的調色板顏色，而不是cols變量中定義的顏色。

結果具有默認顏色

這是dput(head(Top_G))的輸出：

> dput(head(Top_G))
structure(list(Rk = c(352L, 14L, 75L, 1L, 107L, 43L), Name = c("Omar Vizquel",

    BA = c(0.272, 0.262, 0.267, 0.291, 0.288, 0.321), OBP = c(0.336,

"SLG", "OPS", "Birthdate", "Debut", "City", "State", "Pos", "Active"
), row.names = c(NA, -6L), class = c("tbl_df", "tbl", "data.frame"
))

任何提示正確的命令？

提前致謝。

Answer 1

您可以創建一個字符串變量，其名稱為（css有效）或十六進制顏色：

Top_G <- mutate(Top_G, coloract = ifelse(Active == "Activo", "#FF0000", "#00FFFF"))

然后使用：

hc_add_series(Top_G, "column", hcaes(x = Name, y = G, color = coloract), name = "G", showInLegend = FALSE)

您可以使用太colorize功能：

Top_G <- mutate(Top_G, coloract = colorize(Active, c("#FF0000", "#00FFFF")))
