Configures the crosshair labels.
Crosshair labels appear on the chart axes when a user pauses on a series point. They display the argument and the value of this series point.
There are two crosshair labels on a chart - one for each crosshair line, and the label object described here configures both. If you need to set options individually for each label, use the label object within the crosshair.horizontalLine or crosshair.verticalLine object. Individual settings override common ones.
Because the crosshair labels are hidden by default, assign true to the label.visible field if you need them to be shown.

This option supports the following colors:
- Hexadecimal colors

Customizes the text displayed by the crosshair labels.
The text for the crosshair label to display.

To specify an individual function, which will be called for the horizontal or vertical line separately, use the customizeText option within horizontalLine.label or verticalLine.label object.
