My x axis values are changing not moving

I have a problem with my x axis, my chart looks like the first chart:

if you can notice the x axis values are not sliding or moving to the left, the values are changing, and I don't want that

I want my x axis to look like the second chart.

where my x axis values are shifting to the left. How can I achieve this?

Thanks
