Visualforceでエリアグラフ表示

Winter'13でグラフを表示するためのapex:chartが正式にリリースされました。

これを使用してエリアグラフを表示することができます。

Apex

public with sharing class Chart_AreaSeries {
    
    public List<Data> getData() {
        return Chart_AreaSeries.getChartData();
    }
    
    @RemoteAction
    public static List<Data> getRemoteData() {
        return Chart_AreaSeries.getChartData();
    }
    
    public static List<Data> getChartData() {
        List<Data> data = new List<Data>();
        data.add(new Data('Jan', 30, 90, 55));
        data.add(new Data('Feb', 44, 15, 65));
        data.add(new Data('Mar', 25, 32, 75));
        data.add(new Data('Apr', 74, 28, 85));
        data.add(new Data('May', 65, 51, 95));
        data.add(new Data('Jun', 33, 45, 99));
        data.add(new Data('Jul', 92, 82, 30));
        data.add(new Data('Aug', 87, 73, 45));
        data.add(new Data('Sep', 34, 65, 55));
        data.add(new Data('Oct', 78, 66, 56));
        data.add(new Data('Nov', 80, 67, 53));
        data.add(new Data('Dec', 17, 70, 70));
        return data;
    }
    
    public class Data {
        public String name { get; set; }
        public Integer data1 { get; set; }
        public Integer data2 { get; set; }
        public Integer data3 { get; set; }
        public Data(String name, Integer data1, Integer data2, Integer data3) {
            this.name = name;
            this.data1 = data1;
            this.data2 = data2;
            this.data3 = data3;
        }
    }
}
