Axis customization in Vue Chart component

Axis Crossing
An axis can be positioned in the chart area using crossesAt and crossesInAxis properties. The crossesAt
property specifies the values (datetime, numeric, or logarithmic) at which the axis line has to be intersected
with the vertical axis or vice-versa, and the crossesInAxis property specifies the axis name with which the
axis line has to be crossed.
