Question

有一些方法可以在地图类型的图表中设置初始缩放吗？

我有这个选择：

m.setOption({
tooltip : {
    trigger: 'item'
},
toolbox: {
    show : true,
    orient : 'vertical',
    x: 'right',
    y: 'center',
    feature : {
        mark : {show: true},
        dataView : {show: true, readOnly: false},
        restore : {show: true},
        saveAsImage : {show: true}
    }
},
asoluteZoom : {start : 90, end : 100},
series : [
    {
        name: 'Name',
        type: 'map',
        mapType: 'world',
        hoverable: false,
        roam:true,
        data : [],
        markPoint : {
            symbolSize: 10,  
            itemStyle: {
                normal: {
                    borderColor: '#87cefa',
                    borderWidth: 1,       
                    label: {
                        show: false
                    }
                },
                emphasis: {
                    borderColor: '#1e90ff',
                    borderWidth: 5,
                    label: {
                        show: false
                    }
                }
            },
            data : [
                {name: "Hello!"},
            ]
        },
        geoCoord: {
            "Hello!":[-4.729075, 37.906475],

        }
    }
]

}）;

我尝试使用 asoluteZoom ，但没有任何反应。

您可以按照以下方式执行此操作，

var aryDictData = [[String:AnyObject]]()

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        var aryOptionName = [String]()
        var strOptionName = String()

        var cell = DeliveryTableViewCell()
        cell = tableView.dequeueReusableCell(withIdentifier: "DeliveryTableViewCell") as! DeliveryTableViewCell
        cell.selectionStyle = .none

        let productPrice = userDefault.object(forKey: ProductDesConstantNames.KAryStorePrices) as! [String]

         if indexPath.section == 0{
            if indexPath.row < (aryDictData[0]["storeName"]!).count{

               cell.lblItemName.text = ((aryDictData[0]["storeName"]! as AnyObject)[indexPath.row] as! String)

                cell.lblPrice.text = "$\(String(((Double(productPrice[indexPath.row])! + grandTotalProductPrice[indexPath.row]) * Double(numQuntity))))"

                cell.lblItemQuantity.text = "\(numQuntity)x"
                cell.lblItemQuantity.textColor = UIColor.init(red: 41/255, green: 144/255, blue: 85/255, alpha: 1.0)

                let data = aryPreviewOrder[indexPath.row] as! [[String:AnyObject]]
                print(data)

                for i in 0..<((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject).count {
                    let optionName = ((((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject)[i] as AnyObject)["option_name"] as! String)
                    let prices = ((((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject)[i] as AnyObject)["price"] as! String)

                    aryOptionName.append("\(optionName) ($\(prices))")
                    //                    aryOptionPrices.append("($\(prices))")

                    strOptionName = aryOptionName.joined(separator: "\n")
                    //                    strOptionPrice = aryOptionPrices.joined(separator: "\n")
                }
                cell.lblOptionNames.text = strOptionName
               }             
           }
     }
    return cell
}
