jQuery Chart - crosshair.label
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 properties 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 property accepts a function that will be called twice on each point - once for the horizontal line, and then for the vertical. To specify an individual function, which will be called for the horizontal or vertical line separately, use the customizeText property within horizontalLine.label or verticalLine.label object.
See the format section for information on accepted values.
When this property value is
undefined, the date-time axes display larger date range boundaries in labels. For example, if an axis displays months, it also displays a year near each instance of January. If an axis displays days, it also displays a month name near each first visible day mark.
Makes the crosshair labels visible. Applies only if the crosshair feature is enabled.
