第一步：创建Store数据源

var myData = [];
    myData.push({ 'name': '1', 'Oil_Production': '30', 'Water_Injection': '55', 'Gas_Production': '23' });
    myData.push({ 'name': '2', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '3', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '4', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '5', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '6', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '7', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '8', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '9', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '10', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '11', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
    myData.push({ 'name': '12', 'Oil_Production': '20', 'Water_Injection': '25', 'Gas_Production': '63' });
