Flat JSON with multiple data for multi line chart

[Petar]

Hello,

I have relatively simple JSON structure that I would like to use for multi line d3 chart.

data=[
    {
        "sensid0_valhi": 40,
        "sensid0_vallow": 45,
        "time": "2017-04-25T21:05:12"
    },
    {
        "sensid0_valhi": 70,
        "sensid0_vallow": 75,
        "time": "2017-04-25T21:05:13"
    },
    {
        "sensid0_valhi": 80,
        "sensid0_vallow": 85,
        "time": "2017-04-25T21:05:14"
    }]

I need to bind 2 set of data from JSON: first pare time and sensid0_vallow and second pare time and sensid0_valhi.
How can I change my svg.line to create binding for 2 lines in graph:
What I have done so far I think is not OK:
var line = d3.svg.line()
    .x(function (d) {
            return x(d.vrijeme);
        })
    .y(function (d,i) {
            return y(d.value);
         })
  .interpolate("linear");

var chartBody = svg.append("g")
    .attr("clip-path", "url(#clip)");

    chartBody.append("svg:path")
        .datum(data)
        .attr("class", "line")
        .attr("d", line);

thanks
