What is the issue with scaling on the x-axis when using Geom_tile in ggplot?

edit

The issue with scaling on the x-axis when using Geom_tile in ggplot is that each tile is plotted at the center of the corresponding x-value, which can result in the edges of the tile extending beyond the intended x-values. This can lead to visual distortions in the plot and make it difficult to compare the sizes of different tiles accurately.
