How to add XY-line to bar chart creating a multitype chart with another axis?

Question

Just wondering if there would be a possibility to create such a Jasper report chart that would be a combination of many chart types?

In my case I would like to comb

Answer 1

This is follow up on this question How to populate chart data with JavaBeans collection dataSet? (see my answer to understand further details if you like a simple bar chart and use the series expression dynamically)

To achieve a multi axis chart you should use <multiAxisChart> and it will become a little bit more complicated. We can not use the dynamic seriesExpression anymore and need to define each series manually, therefore I will use your original bean but still in a separated datasource.

Java bean

public class WorkingHours {

    private int month = 0;
    private double hoursNormal = 0;
    private double hoursTravel = 0;
    private double hoursOvertime = 0;
    private double hoursTotalCumulative = 0;

    public WorkingHours(int month, double hoursNormal, double hoursTravel, double hoursOvertime, double hoursTotalCumulative) {
        super();
        this.month = month;
        this.hoursNormal = hoursNormal;
        this.hoursTravel = hoursTravel;
        this.hoursOvertime = hoursOvertime;
        this.hoursTotalCumulative = hoursTotalCumulative;
    }
    //getter and setter
}

Fill with data (use your logic) and pass as java.util.List in parameter

List<WorkingHours> list = new ArrayList<WorkingHours>();
list.add(new WorkingHours(1, 2.3, 1.2, 2.1,4.1));
list.add(new WorkingHours(2, 5.3, 2.2,3, 9.1));
list.add(new WorkingHours(3, 3.1, 0.5, 2.0, 20.5));
Map<String, Object> paramMap = new HashMap<String, Object>();
paramMap.put("CHART_DATA", list);

        </band>
    </summary>
</jasperReport>

Key points:

We use <multiAxisChart> with 2 <axis> on one the <lineChart> on the other <barChart>, for the <barChart> we define every <categorySeries> separately.
