Customization

The fill and textStyle property of the crosshairTooltip is used to customize the background color and font style of the crosshair label respectively. Color and width of the crosshair line can be customized by using the line property in the crosshair.

Crosshair label customization

The crosshairLabelRender event is triggered before each crosshair axis label is rendered in the stock chart. This event provides the ability to customize the appearance and content of crosshair labels, or to conditionally prevent specific labels from being displayed.

The event arguments include:

  • text – The default text for the crosshair label. You can modify this value to display custom content.
  • value – The actual data value at the crosshair position.
  • axisName – The name of the axis associated with the label.
  • axisOrientation – The orientation of the axis, either Horizontal or Vertical.
  • textStyle – Font properties for the label text, allowing customization of font family, size, weight, and color.
  • fill – The background color of the crosshair label.
  • cancel – Set this to true to prevent the label from being rendered.
