How do I remove the blank area behind 0 in my plots?

I want to remove the white space behind the lowest x-axis value in my plot. How do I get rid of this?

UPDATE : I found the solution. I just added two lines. One removing the expansion and the other expanding the right side. (I might have worded this incorrectly, I'm sorry as English is not my native language.)

scale_y_continuous(expand = c(0,0)) +
  expand_limits(y = c(0, 400)) # Could be anything depending on the values of the axis
