Remarks

You can use the Axis property to identify and access an axis at the inspected point; that is, when the HitCode property returns one of the following values:

Axis

The inspected point belongs to an axis in an XY diagram.

You can use Axis and Diagram properties to access the inspected axis and its parent diagram, respectively.

AxisValueLabel

The inspected point belongs to an axis value label in an XY diagram.

You can use AxisValueLabel, Axis, and Diagram properties to access the inspected value label and its parent axis and diagram, respectively.

AxisTitle

The inspected point belongs to an axis title.

You can use Title and Axis properties to access the inspected title and its parent axis, respectively. Cast the Title property value to the TdxChartAxisTitle class to access all public API members of the inspected axis title.

When the inspected point belongs to an axis, you can also use the Diagram property to access the parent XY diagram of the inspected axis.
