使用 ggplot 在 R 中绘制时间序列

Question

我有一个包含两列的数据框。第一个是发出请求的数据时间，格式为小时:分钟:秒。第二列包含完成请求所需的分钟数。

当我在 R 基础中使用“plot()”时，它会毫无问题地为我提供基本的散点图。当我尝试将其放入 ggplot 时，我得到以下结果：

“警告：[38;5;250m所有的美学长度都是1，但是数据有87行。[36mℹ[38;5;250m 你是想使用`annotate()`吗？[39m”。

它确实显示了一个图，但它只是带有单个点的两个轴。

我已将数据框放入 dput() 函数并粘贴下面的输出

我正在尝试使用 ggplot 将其绘制为散点图

ggplot(time_frame, aes(`Order Time`, `Order to Final (min)`)) + geom_point()
