Overview

Adding a legend to Watchr graphs is easy. All you need to do is add "legend": "true" to the "plot" section of your config, as shown below.

Watchr Config: config.json

{
    "plots" : {
        "files" : {
            "fileName": "performance_*",
            "type" : "json"
        },
        "plot" : [
            {
                "name" : "Plot with Legend",
                "legend" : "true",
                "dataLines" : [
                    {
                        "name" : "Data Line",
                        "x" : {
                            "getPath": "performance-report/nightly_run_*",
                            "getKey" : "date",
                            "unit" : "date"
                        },
                        "y" : {
                            "getPath": "performance-report/nightly_run_*/measurement",
                            "getKey" : "value",
                            "unit" : "seconds"
                        }
                    }
                ]
            }
        ]
    }
}

Data File: performance_data.json

{
    "performance-report" : {
        "nightly_run_2021-04-05" : {
            "date" : "2021-04-05T22:21:21",
            "measurement": {
                "value":"1.0"
            }
        }
    }
}
