Axis Customization in Angular Stock Chart component

05 Aug 2021 / 6 minutes to read

Axis Crossing

An axis can be positioned in the Stock 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.
