geom_bar的宽度和间隙（ggplot2）

我想使用ggplot制作条形图。当我做export>copy to clipboard并绘制图，然后尝试调整图的大小后，随着我更改图的大小，条形图之间的间隙会发生变化（条形图之间的间隙会更改其位置）。

我希望我对此很清楚。我使用了以下代码：

ggplot(df, aes(Day, Mean)) +
 geom_histogram(stat = "identity", position = "stack") +
 theme(axis.text = element_text(size=12, colour =  'black')) +
 ylim(0, 50) + xlim(0, 365)

我曾尝试同时使用geom_bar和和geom_histogram，两者似乎都给出了相同的情节。随着我调整尺寸，条形之间的间隙也会改变。

PS我必须绘图365 bars，每个代表一年的一天。如果您认为我不清楚，请随时编辑问题。

这是用代码生成的图。您可以清楚地看到两者之间的不均匀间隙。
