What problem does this feature solve?

When drawing the function image, the set scale is always calculated from the leftmost end of the horizontal axis or the bottom of the vertical axis(like the graph as follows), we want the scale to start from 0 to both ends. As shown in the following figure, how to achieve the scale interval is still 6, but display the results of the scale is -18,-12,-6,0,6,12,18?
