Syntax

updateTooltipPosition3d();

Description

The updateTooltipPosition3d method updates tooltip position for an area of 3D map layer.

Example

To execute the example the HTML page must contain the MapChart component named map and the ). A map with the Sphere topobase must also be loaded (see the page with description of the MapChart.AmbientLightValue propertyToolBar property named MapType (see . Example of Creating the MapChart Component). A map with the Sphere topobase must also be loaded (see the page with description of the MapChart.AmbientLightValue property).

Draw a tooltip for an area of 3D map layer with the RU identifier:

// Get map layer area with the RU identifier
var shape = map.getShape("RU");
// Enable a tooltip showing
shape._tooltipOn = true;
// Create a new tooltip
var toolTip = new PP.MapToolTip({
    Chart: map
});
// Set the tooltip for the map layer area
shape.setToolTip(toolTip);
// Get setting for the tooltip
var vals = map.getTooltipValues(shape, "No data");
// Render created tooltip
toolTip.draw(map.getLayer("Regions"), map.getToolTipLayer(), vals);
// Set the tooltip layout
var vec = shape.getCenter();
var cx = Math.sqrt(vec.dot(vec));
shape._tooltipRelX = Math.atan2(vec.getX(), vec.getZ());
shape._tooltipRelY = Math.asin(vec.getY() / cx);
// refresh the tooltip layout
shape.updateTooltipPosition3d();

After executing the example a tooltip is shown for the 3D map layer area with the RU identifier:
