SFDC：棒グラフと折れ線グラフ

<apex:chart>タグで棒グラフと折れ線グラフを一緒に表示する方法です。

Apexクラス・サンプル

public class Chart_ChartTips {

    public List<Data> getData() {
        return Chart_ChartTips.getChartData();
    }
    
    @RemoteAction
    public static List<Data> getRemoteData() {
        return Chart_ChartTips.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;
        }
    }
}

Visualforceページ・サンプル

<apex:page controller="ChartController">
    <apex:chart height="400" width="700" data="{!data}">
        <apex:legend position="right"/>
        <apex:axis type="Numeric" position="left" fields="data1"  title="Opportunities Closed" grid="true"/>
        <apex:axis type="Numeric" position="right" fields="data3"  title="Revenue (millions)"/>
        <apex:axis type="Category" position="bottom" fields="name"  title="Month of the Year">
            <apex:chartLabel rotate="315"/>
        </apex:axis>
        <apex:barSeries title="Monthly Sales" orientation="vertical" axis="right"  xField="name" yField="data3">
            <apex:chartTips height="20" width="120"/>
        </apex:barSeries>
        <apex:lineSeries title="Closed-Won" axis="left" xField="name" yField="data1"  fill="true" markerType="cross" markerSize="4" markerFill="#FF0000"/>
        <apex:lineSeries title="Closed-Lost" axis="left" xField="name" yField="data2"  markerType="circle" markerSize="4" markerFill="#8E35EF"/>
    </apex:chart>
</apex:page>

<chart>内に<apex:barSeries>や<apex:lineSeries>などを一緒に宣言することで

様々なグラフを一緒に表示できるようです。

他にも組み合わせがあるかもしれないです。
