Example

To execute the example the HTML page must contain the MapChart component named map containing bar factors (see MapBar Constructor):

// Get accident bar factor
bar = mapBar.getLayer().getMapBarCollection()[3];
// Set visibility
bar.setIsVisible(true); 
map.refresh();
// Get bar factor identifier
barId = bar.getId();
// get data mapping identifier
barV = bar.getVisual();
dMapId = barV.getColorMappingsId();
// Select bar factor
selBar = {};
selBar[barId] = {};
selBar[barId][dMapId] = true;
map.setSelectedBars(selBar);
// Check attribute of hovering over bar factors
console.debug(map.getHoveredBars());

After executing the example selecting is set for the bar factor with the 3 index. The console shows identifiers of bar factors to which hovering is applied (the mouse cursor is hovered).
