Fit Baidu map to multiple markers like Google Maps fitBounds

问题

Is there an equivalent in Baidu like fitBounds in GoogleMap? I have multiple markers on a Baidu map and I would like to show all the markers with the proper positioning and zoom level.

Just stumbling upon this thread. The answer to this question is:

var points = [Point_1,...,Point_n];
map.setViewport(points);

points is simply an array containing objects of type BMap.Point that you want within the map viewport.

It is possible to show multiple markers on Baidu Map.

Check their example here

I have displayed Baidu Map with an area of 230x125 so I have shown the China on the area like below:

var map     = new BMap.Map("id_of_map_loading_area");
var point   = new BMap.Point(101.841797,35.433724); //China on the center of the area
map.centerAndZoom(point,3);  // Change value 3 to see difference
map.enableScrollWheelZoom(); // Zoom effect to the map using mouse.

Although this answer worked for me, with the change of direct latlng object instead of BMap.Point object to make it work.
