In order to generate a chart report from a JSON file you have to :

  1. Write the JSON file with the chart configuration.

    {
        "type": "line",
        "data": {
            "datasets": [{
                "data": [20, 50, 100, 75, 25, 0],
                "label": "Left dataset",
                "fill" : true,
                "backgroundColor" : "rgba(66, 182, 244, 0.2)",
                "borderColor" : "#42b6f4",
                "yAxisID": "left-y-axis"
            }, {
                "data": [0.1, 0.5, 1.0, 2.0, 1.5, 0],
                "label": "Right dataset",
                "fill" : true,
                "backgroundColor" : "rgba(244, 65, 86, 0.2)",
                "borderColor" : "#f44156",
                "yAxisID": "right-y-axis"
            }],
            "labels": ["Jan", "Feb", "Mar", "Apr", "May", "Jun"]
        },
        "options": {
            "scales": {
                "yAxes": [{
                    "id": "left-y-axis",
                    "type": "linear",
                    "position": "left"
                }, {
                    "id": "right-y-axis",
                    "type": "linear",
                    "position": "right"
                }]
            }
        }
    }

  2. Write the SIL script which reads the JSON file.

    string json = readFromTextFile("multipleAxes.json");
    SILReportingChart chart = fromJson(json);
     
    return chart;

The generated report:
