Stacked Barchart

Question

I want to create a chart with stacked bars and a line, but it just works if I doesn't stack.

Public Class APPBWS_ChartData {
    Public String Month { get; set; }
    Public Double Data1 { get; set; }
    Public Double Data2 { get; set; }
    Public Double Data3 { get; set; }    
    public ChartData(String Month, Double Data1, Double Data2, Double Data3) {
        this.Month = Month;
        this.Data1 = Data1;
        this.Data2 = Data2;        
        this.Data3 = Data3;        
    } 
}

Public List<ChartData> getData() {
    List<ChartData> data = new List<ChartData>();
    data.add(new ChartData('Jan', CY_01_APPBWS, CY_01_APPBWS_STO, CY_01_ZS));
    data.add(new ChartData('Feb', CY_02_APPBWS, CY_02_APPBWS_STO, CY_02_ZS));
    data.add(new ChartData('Mar', CY_03_APPBWS, CY_03_APPBWS_STO, CY_03_ZS));
    data.add(new ChartData('Apr', CY_04_APPBWS, CY_04_APPBWS_STO, CY_04_ZS));
    data.add(new ChartData('May', CY_05_APPBWS, CY_05_APPBWS_STO, CY_05_ZS));
    data.add(new ChartData('Jun', CY_06_APPBWS, CY_06_APPBWS_STO, CY_06_ZS));        
    data.add(new ChartData('Jul', CY_07_APPBWS, CY_07_APPBWS_STO, CY_07_ZS));
    data.add(new ChartData('Aug', CY_08_APPBWS, CY_08_APPBWS_STO, CY_08_ZS));
    data.add(new ChartData('Sep', CY_09_APPBWS, CY_09_APPBWS_STO, CY_09_ZS));
    data.add(new ChartData('Oct', CY_10_APPBWS, CY_10_APPBWS_STO, CY_10_ZS));
    data.add(new ChartData('Nov', CY_11_APPBWS, CY_11_APPBWS_STO, CY_11_ZS));
    data.add(new ChartData('Dec', CY_12_APPBWS, CY_12_APPBWS_STO, CY_12_ZS));
    return data;
}

Answer 1

My fault, the problem was the space behind the Data1,SPACE.
