dataType: "json",        //json
   success: function (data) {

       var arr = new Array();

           }
       });
   },

what result do you expect? What is the error message actually seen?

dataView should be in feature, not directly under toolbox.


http://www.echartsjs.com/opti.
toolbox.feature.dataView

myChart.setOption({ 
    ...,
    toolbox:{
        feature:{
            dataView:...
        }
    }
})
