1. Create a new datasource - say `props.dataSources.marker1`.
2. In that datasource create two data points. (I don't know what your x-axis is so I've just used the default t\_stamp. You'll need to modify to suit.)

```auto
0
    t_stamp : "Tue Aug 09 2018",
    y: 0
1
    t_stamp : "Tue Aug 09 2018",
    y: 1

```

1. Add a new `props.series`. Set the following items:

```auto
1
    data
        source : marker1
        x : t_stamp
        y : y
    xAxis : <set to same as your existing series>
    yAxis : <set to same as your existing series> 
    line
        appearance
            stroke
                color : red

```

1. Do the same for `marker2` if required.
