绘制作物日历
我有一个csv文件（crop_calendar.csv），其中包含特定地区作物发育阶段的信息。基本上每行都有以下结构：
crop_name sowing_dat emergence_date flowering_date maturity_date harvest_date
例如：
Winter_wheat 18.08 28.08 24.06 30.07 3.08
Winter_rye 18.08 28.08 15.06 23.07 29.07
Spring_wheat 27.04 10.05 1.07 4.08 7.08
Spring_barley 27.04 12.05 27.06 1.08 5.08
现在，我想将这些信息放在一个看起来像这样的图形中：
知道如何使用大量裁剪（行）和不同位置吗？

这是一个例子，假设你有播种的day.of.year（）和每个作物和每个国家的三个时期的持续时间（以天为单位）。

答案 1 :(得分：2)
要在每个"color=.."的{{1}}来电中添加图例广告aes()，然后使用参数geom_linerange()添加scale_color_identity() - 这将使用颜色名称作为实际颜色。使用guide="legend"，您可以更改图例中的标签。要删除月份之间的行，请在labels=内添加minor_breaks=NULL。
scale_y_date() 
答案 2 :(得分：1)
猜测你想做什么有点困难。只有3个日期，您无法重现您显示的图表（每个作物需要4个日期）。目前还不清楚这些数字代表什么（大概是几周？）。如果这只是一个关于绘图的问题，这将让你开始。否则，请澄清问题。
df <- read.table(text="crop_name emergence_date maturity_date harvest_date
wheat 13.04 25.05 30.06
corn 12.02 21.30 23.11", header=TRUE)
require(ggplot2)
ggplot(df, aes(x=crop_name)) +
geom_linerange(aes(ymin=emergence_date, ymax=maturity_date), color="green3", size=5) +
geom_linerange(aes(ymin=maturity_date, ymax=harvest_date), color="yellow", size=5) +
coord_flip() + ylim(0, 52)

好的编译答案和其他研究，这是我最终得到的解决方案：
inDf <- read.table(text="crop sowing emergence flowering maturity harvesting

Maize 25/05/2013 6/06/2013 18/08/2013 10/09/2013 12/09/2013", header=TRUE)
inDf[, "sowing"] <- as.Date(inDf[, "sowing"], format = '%d/%m/%Y')
inDf[, "emergence"] <- as.Date(inDf[, "emergence"], format = '%d/%m/%Y')
inDf[, "flowering"] <- as.Date(inDf[, "flowering"], format = '%d/%m/%Y')
inDf[, "maturity"] <- as.Date(inDf[, "maturity"], format = '%d/%m/%Y')
inDf[, "harvesting"] <- as.Date(inDf[, "harvesting"], format = '%d/%m/%Y')
ggplot(inDf, aes(x=crop)) +
geom_linerange(aes(ymin=sowing, ymax=emergence), color="green", size=5) +
geom_linerange(aes(ymin=emergence, ymax=flowering), color="green3", size=5) +
geom_linerange(aes(ymin=flowering, ymax=maturity), color="yellow", size=5) +
geom_linerange(aes(ymin=maturity, ymax=harvesting), color="red", size=5) +
coord_flip() + scale_y_date(lim = c(as.Date("2012-08-15"), as.Date("2013-09-01")),breaks=date_breaks(width = "1 month"), labels = date_format("%b"))+
ggtitle('Crop Calendar')+ xlab("")+ylab("")

我现在要添加图例并删除每个月之间的所有白线。有任何想法吗？感谢
