Axis Customization in Vue Chart component

14 Apr 2021 / 8 minutes to read

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.

Multiple Axis

In addition to primary X and Y axis, we can add n number of axis to the chart. Series can be associated with this axis, by mapping with axis’s unique name.

Inversed Axis

When an axis is inversed, highest value of the axis comes closer to origin and vice versa. To place an axis in inversed manner set this property isInversed to true.
