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.

ReactDOM.render(<App />, document.getElementById("charts"));You can add a title to the axis using title property to provide quick
information to the user about the data plotted in the axis. Title style can be customized using titleStyle
property of the axis.

majorTickLines and
minorTickLines properties in the axis.

ReactDOM.render(<App />, document.getElementById("charts"));You can customize the width, color and dashArray of the minor and major grid lines,
using majorGridLines and

ReactDOM.render(<App />, document.getElementById("charts"));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.

ReactDOM.render(<App />, document.getElementById("charts"));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.

ReactDOM.render(<App />, document.getElementById("charts"));To place an axis opposite from its original position, set
opposedPosition property of the axis to true.
