Hints: Crosshair Cursor

A Cartesian Chart can show a hint as a standard tooltip or a Crosshair Cursor.

How to: Specify the Crosshair Cursor behavior

Use the following code to specify the Cartesian Chart's hint type:

Hint hint = new Hint();
hint.setEnabled(true);
chart.setHint(hint);
CrosshairHintBehavior behavior = new CrosshairHintBehavior();
behavior.setMaxSeriesCount(3);
behavior.setGroupHeaderTextPattern("{A$MMM/dd/YYYY}");
hint.setBehavior(behavior);

The Hint.setBehavior(HintBehavior) method specifies the hint's behavior. The following behaviors are available:

Behavior Example Description
TooltipHintBehavior Tooltip A hint behaves like a tooltip.
CrosshairHintBehavior Crosshair A hint behaves like a crosshair cursor.

How to: Configure a hint interaction with an axis

In addition to a hint-series interaction, Cartesian Chart's hint interacts with an axis. The following code demonstrates how to disable a specific axis' Crosshair line and label:

AxisHintOptions axisHintOptions = new AxisHintOptions();
axisHintOptions.setLabelVisible(false);
axisHintOptions.setLineVisible(false);
yAxis.setHintOptions(axisHintOptions);

The following symbols configure how the Crosshair Cursor interacts with an axis:

Symbol Description
AxisHintOptions The axis hint options storage.
AxisBase.setHintOptions(AxisHintOptions) Specifies axis hint options.

How to: Snap the Crosshair label to a chart's corner

The Crosshair label can follow the Crosshair's argument line or settle any chart corner.

Static crosshair label

The following sample demonstrates how to snap the Crosshair label to the Chart's top-right corner:

Hint hint = new Hint();
chart.setHint(hint);
CrosshairHintBehavior behavior = new CrosshairHintBehavior();
behavior.setMaxSeriesCount(3);
hint.setBehavior(behavior);
StaticCrosshairLabelPosition crosshairLabelPosition = new StaticCrosshairLabelPosition();
crosshairLabelPosition.setVerticalAlignment(LabelPositionVerticalAlignment.TOP);
crosshairLabelPosition.setHorizontalAlignment(LabelPositionHorizontalAlignment.RIGHT);
behavior.setLabelPosition(crosshairLabelPosition);

The following position modes specify the label's position:

Position Sample Image Description
StaticCrosshairLabelPosition Crosshair static label A Crosshair's Label has a static position.
LineTrackingCrosshairLabelPosition Crosshair dynamic label Defines the crosshair label's behavior when it follows the cursor.
