Recently the company has an ArcGIS API for JS Project, need to use the Baidu echarts migration map effect, and Baidu that effect is a combination of Baidu map, how can be combined with ArcGIS API, online search, finally found in GitHub, GitHub Source code address: https://github.com/wandergis/arcgis-echarts; In this, thank the original author Wandergis selfless dedication;

Integrate your demo as follows:

Implementation ideas:

1. Customize the Echartslayer class, in order to bind the rendering effect of the Echarts migration map with ESRI maps, for example, the d of the render map effect is placed in the map container:

      this. _echartscontainer =       document.createelement (' div ');       = ' absolute ';       = "Moveecharts_map";       = map.height + ' px ';       = map.width + ' px ';       = 0;       = 0;      Map.__container.appendchild (div);

Binding Series events for maps:

      /** * handling of Bound map events * * @private*/self._bindevent=function() {Self._map.on (' Zoom-end ',function(e) {self.setoption (self._option);        }); Self._map.on (' Zoom-start ',function(e) {self._ec.clear ();        }); Self._map.on (' Pan ',function(e) {self._ec.clear ();        }); Self._map.on (' Pan-end ',function(e) {self.setoption (self._option);        }); Self._ec.getzrender (). On (' DragStart ',function(e) {Self._map.disablepan (); //self._ec.clear ();        }); Self._ec.getzrender (). On (' Dragend ',function(e) {Self._map.enablepan (); //self.setoption (self._option);        }); Self._ec.getzrender (). On (' MouseWheel ',function(e) {self._ec.clear (); Self._map.emit (' Mouse-wheel ', E.event)}); };

Specific can see GitHub source code

2.echarts migration diagram of the simulation data structure, here itself slightly modified, and GitHub source code to construct data inconsistent:

3. Invoke the implementation:

    function (map) {        varnew  moveechartsmap.echartslayer (map, echarts);         var chartscontainer = overlay.getechartscontainer ();         var mychart = overlay.initecharts (chartscontainer);         = mychart.onresize;        overlay.setoption (option);    }
