regionStyle Object Set the styles for the map's regions. Each region or marker has four states: initial (default state), hover (when the mouse cursor is over the region or marker), selected (when region or marker is selected), selectedHover (when the mouse cursor is over the region or marker and it's selected simultaneously). Styles could be set for each of this states. Default value for that parameter is:

  },
  selectedHover: {
  }
}
regionLabelStyle Object Set the styles for the regions' labels. Each region or marker has four states: initial (default state), hover (when the mouse cursor is over the region or marker), selected (when region or marker is selected), selectedHover (when the mouse cursor is over the region or marker and it's selected simultaneously). Styles could be set for each of this states. Default value for that parameter is:
{
  initial: {
    'font-family': 'Verdana',
    'font-size': '12',

    "stroke-width": 2,
    cursor: 'pointer'
  },
  selected: {
    fill: 'blue'
  },
  selectedHover: {
  }
}
markerLabelStyle Object Set the styles for the markers' labels. Default value for that parameter is:
{

}
markers Object | Array Set of markers to add to the map during initialization. In case of array is provided, codes of markers will be set as string representations of array indexes. Each marker is represented by latLng (array of two numeric values), name (string which will be show on marker's tip) and any marker styles.
series Object Object with two keys: markers and regions. Each of which is an array of series configs to be applied to the respective map elements. See DataSeries description for a list of parameters available.
focusOn Object | String This parameter sets the initial position and scale of the map viewport. See setFocus docuemntation for possible parameters.
labels Object Defines parameters for rendering static labels. Object could contain two keys: regions and markers. Each key value defines configuration object with the following possible options:
  • render {Function} - defines method for converting region code or marker index to actual label value.
  • offsets {Object|Function} - provides method or object which could be used to define label offset by region code or marker index.
Plase note: static labels feature is not supported in Internet Explorer 8 and below.
selectedRegions Array | Object | String Set initially selected regions.
selectedMarkers Array | Object | String Set initially selected markers.
onRegionTipShow Function (Event e, Object tip, String code) Will be called right before the region tip is going to be shown.
onRegionOver Function (Event e, String code) Will be called on region mouse over event.
onRegionOut Function (Event e, String code) Will be called on region mouse out event.
onRegionClick Function (Event e, String code) Will be called on region click event.
onRegionSelected Function (Event e, String code, Boolean isSelected, Array selectedRegions) Will be called when region is (de)selected. isSelected parameter of the callback indicates whether region is selected or not. selectedRegions contains codes of all currently selected regions.
onMarkerTipShow Function (Event e, Object tip, String code) Will be called right before the marker tip is going to be shown.
onMarkerOver Function (Event e, String code) Will be called on marker mouse over event.
onMarkerOut Function (Event e, String code) Will be called on marker mouse out event.
onMarkerClick Function (Event e, String code) Will be called on marker click event.
onMarkerSelected Function (Event e, String code, Boolean isSelected, Array selectedMarkers) Will be called when marker is (de)selected. isSelected parameter of the callback indicates whether marker is selected or not. selectedMarkers contains codes of all currently selected markers.
onViewportChange Function (Event e, Number scale) Triggered when the map's viewport is changed (map was panned or zoomed).
