我怎样才能将这些数据点清楚地添加到图表中，而不会让它们看起来像它们那样？

Question

我有两个数据框（本问题末尾的dput()s）我希望绘制到同一个图表上。

我希望能够显示任何给定日期（列）的第一次和第二次预约号码，以及每个日期接种的每种疫苗的数量，按地点细分。我对原始数据执行了count（使用dplyr），但我认为通过每天按站点绘制，它导致我的图表显示堆叠值而不是单个/总值：

我高度怀疑我的处理方法是错误的，这就是导致列和行看起来像它们的方式的原因；它在很多层面上似乎都是错误的。

我认为列被分解成段（因为它们是许多值的组合），都堆叠在一起，我相信线也是如此。

就这一行而言，显然有问题，因为它似乎从一列跳到下一列；没有平滑/流畅的过渡。我已按单日值拆分数据，但仍然会发生这种情况。

（为了这个例子，我添加了粗体颜色；这个图表不是最终形式。）

我尝试使用merge 来组合数据集，但仍然收到相同的结果；我确信有更好的方法来做到这一点。

任何建议都会很棒。

merge 数据帧的代码：

merged <- merge(df, df2, by = 1)
colnames(merged)[1] <- "apptDTS" # Change first column name

图表代码：

ggplot(merged) +
geom_col(aes(apptDTS, n.x), fill = "yellow", colour = "black") +
geom_col(aes(apptDTS, n.y), fill = "blue", colour = "black") +
geom_line(aes(x = apptDTS, y = n.x),
          colour = "green") +
geom_line(aes(x = apptDTS, y = n.y),
          colour = "red")

dputs:

Answer 1

如果我理解正确，OP想要显示

• 任何给定日期的第一个和第二个约会号码
• 每个日期接种的每种疫苗的数量
• 按位置细分。

但是，我不确定我是否完全理解了这些要求。因此，我的回答可能需要根据 OP 的反馈进行调整。

以下是我将使用我喜欢的工具执行的操作（我使用 data.table 比使用 dplyr 更熟悉和更快）。最重要的是，我不是merge()，而是rbind() 两个输入数据集，第一次和第二次约会都有一个 id 列。

library(data.table)
library(magrittr)
cols <- c("appDTS", "siteLocation", "vaccineType", "n")
combi <- list(df, df2) %>% 
  lapply(setDT) %>% 
  lapply(setnames, cols) %>% 
  rbindlist(idcol = "appt") %>%
  .[, appt := factor(appt, labels = c("First", "Second"))]

# 1st plot
ggplot(combi) + 
  aes(appDTS, n, fill = appt) + 
  geom_col() +
  scale_fill_brewer(palette = "Paired")

# 2nd plot
ggplot(combi) + 
  aes(appDTS, n, fill = vaccineType) + 
  geom_col() +
  scale_fill_brewer(palette = "Accent")

# 3rd plot
ggplot(combi) + 
  aes(appDTS, n, fill = siteLocation) + 
  geom_col()

请注意，我为每个图选择了不同的调色板，以可视化不同的变量进行颜色编码。

编辑

OP 有clarified:

我想要一个在 x 轴上显示日期的图， y 轴上的计数，包括条形图和两条线 表明每天每种疫苗接种了多少次。

为了绘制每天接种的疫苗数量，我们需要进一步汇总数据。使用data.table，这是由

完成的

combi[!is.na(n), .(n = sum(n)), by = .(appDTS, vaccineType)]

现在，可以通过以下方式创建带有线条叠加的图

ggplot(combi) + 
  aes(appDTS, n, fill = appt) + 
  geom_col() +
  scale_fill_brewer(palette = "Paired") + 
  geom_line(
    aes(appDTS, n, colour = vaccineType),
    data = combi[!is.na(n), .(n = sum(n)), by = .(appDTS, vaccineType)],
    inherit.aes = FALSE, size = 1) +
  scale_color_brewer(palette = "Set1")

需要inherit.aes = FALSE 以避免由于聚合数据集中缺少appt 变量（映射到fill 美学）而出现错误消息。
