问我可以从多个数据源(本例中为多个HighCharts )创建一个单一的GoogleSheets图吗？

        //Function to produce a data array ***Not Working - Cannot extract array from object method***
    function getData(){

    Highcharts.data({
        googleSpreadsheetKey: '12x66_QEkTKg_UzvpHEygdTmfnu7oH81pSQYn78Hxt80',
        googleSpreadsheetWorksheet: 4,
        startColumn: 16,
        endColumn: 22,
        startRow: 63,
        endRow: 76,

        parsed: function (columns) {
            var dataTest2 = [];
            var columnLength = columns[1].length;
            for (i = 0; i < columnLength; i = i + 1) { 
                dataTest2.push(columns[1][i]);

            }

            alert(dataTest2); //This works here, but not if I move it outside of the method, even if I return it.
            var testReturn = this.googleSpreadsheetKey; //trying to return any property using "this" - I've also tried this.googleSpreadsheetKey.value but still undefined
            return testReturn; //returns "Undefined" 
        }

    });


    }
