function formatDataf(data)

            var formatArray = [];
            data.forEach(function (item) 

                item.value = 1;
                var sarry = formatArray.some(function (itemarr) //判断是否有重复的
                    if (item.x == itemarr.x && item.y == itemarr.y) 
                        itemarr.value = itemarr.value + 1;
                        return true;
                     else
