篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用ggplot绘制时导入库存数据问题相关的知识，希望对你有一定的参考价值。
我一直试图导入这个雅虎财务代码并使用ggplot绘制它，但每当我尝试这样做时，x轴显示多行（如下所示）。另外，如附图所示，我不确定为什么日期会以这种方式出现。谢谢
这是代码
axdata <- read.csv("AXJO.csv")
axdata$Date <- as.Date(axdata$Date)
plt <- ggplot(axdata, aes(x =Date, y = axdata$Close))
这是数据。我保留了所有重要的细节，但删除了大量的价格数据和日期，以保持字符数限制。
> dput(axdata)

我会的
答案
首先，看起来您在阅读数据时遇到问题。您的所有字段都已作为字符而不是数字读入。你需要检查那里发生了什么。
其次，如果要加载yahoo数据，可以使用quantmod包。
library(quantmod)
# get the data
axdata <- getSymbols("^AXJO", from = "2018-09-01", auto.assign = FALSE)
绘制数据：
chartSeries(axdata)
或者你想在tidyquant软件包中处理整洁的数据。但是，这也安装了很多其他软件包，但你会得到一些额外的功能，如geom_candlestick，所以你可以在ggplot2中绘制股票数据。
library(tidyquant)
axdata2 <- tq_get("^AXJO", from = "2018-09-01")
axdata2 %>%
ggplot(aes(x = date, y = close)) +
geom_line()
以上是关于使用ggplot绘制时导入库存数据问题的主要内容，如果未能解决你的问题，请参考以下文章
