气泡图中的气泡未按精确的年月值（x轴）对齐

Question

我有一个气泡图，它有一个简单的3列数据源。对于x轴我使用YYYY-MM格式，我想显示一些COUNT的总数。我期待所有气泡在x轴年月日期垂直对齐，但这不是我得到的。我想知道为什么？以及是否有理由进行这样的分配（ggplot2如何在年月日期选择那些x值而不是x值）？

代码：

正如@nielfws指出的那样，您正在使用geom_jitter，这实际上是geom_point(position = "jitter")的快捷方式。如果您更关心与x轴的对齐，可以使用position变量指定垂直闪避。

g <- ggplot(df, aes(x=YMDate, y=`Total Material Count`)) + 
  scale_y_log10() +
  scale_size_continuous(trans="sqrt",
                        range = c(2, 20),
                        breaks=c(1,5,10,50,100,500,1000,2000,3000)) +
  labs(subtitle="Size of Bubble= Total Material Count in MMRs",
       title="MMR Distribution - Monthly")

g <- g + geom_point(aes(col=Business, size=`Total Material Count`), alpha=0.7,
position = position_dodge(height = 1)) + 
  geom_smooth(aes(col=Business), method="lm", se=F)

您还可以在width中指定position_dodge选项。四处游来获得理想的效果。
