======================================

• 根據組更改條形圖顏色

可以將顏色指定爲十六進制RGB三元組，例如“＃FFCC00”或名稱。還可以使用其他顏色比例，例如從RColorBrewer包中提取的顏色比例。 這裏已經詳細描述了R中可用的不同顏色系統。 要根據組更改條形圖顏色，必須使用參數groupName指定包含組的數據列的名稱。 使用參數groupColors，通過十六進制代碼或名稱指定顏色。 在這種情況下，groupColors的長度應該與組的數量相同。 使用參brewerPalette，使用RColorBrewerpalette指定顏色。

# Color the stripchart accoording to the groupName "dose"
ggplot2.stripchart(data=df, xName='dose',yName='len',
        groupName='dose')
# Change group colors using hexadecimal colors
ggplot2.stripchart(data=df, xName='dose',yName='len',
        groupName='dose',
        groupColors=c('#999999','#E69F00','#56B4E9'))
# Change group colors using brewer palette: "Paired"
ggplot2.stripchart(data=df, xName='dose',yName='len',
        groupName='dose',brewerPalette="Paired")
# Change group colors using color names
ggplot2.stripchart(data=df, xName='dose',yName='len',
      groupName='dose',
      groupColors=c('aquamarine3','chartreuse1','goldenrod1'))

• 標註/位置

# Change the legend position to "top" 
  # (possible values: "left","top", "right", "bottom")
ggplot2.stripchart(data=df, xName='dose',yName='len',
        groupName='dose', legendPosition="top")
# legendPosition can be also a numeric vector c(x, y)
ggplot2.stripchart(data=df, xName='dose',yName='len',
        groupName='dose', legendPosition=c(0.8,0.2))

• 標註背景邊框

# Change legend background color, title and text font styles
ggplot2.stripchart(data=df, xName='dose',yName='len',
    groupName='dose',
    #legendTitleFont=c(size, style, color)
    legendTitle="Dose (mg)", legendTitleFont=c(10, "bold", "blue"),
    #legendTextFont=c(size, style, color)
    legendTextFont=c(10, "bold.italic", "red"),
    #legendBackground: c(fill, lineSize, lineType, lineColor)
    legendBackground=c("lightblue", 0.5, "solid", "darkblue" )
    )

• 隱藏標註

# Change the order of items in the legend
 # legendItemOrder : character vector indicating 
# the order of items in the legends.

            groupName='dose',
            legendItemOrder=c("2", "1", "0.5"))
