[Solved] Legend not being displayed

<div class="chart-cell">
    <div id="chart" />
</div>

$.get("/chart/GetCustomPlotData", data, function (response) {
    if (response.Success) {
        var result = response.Result;

        if (result.IsAggregated) {
            $("#data-point-count").text(result.DataSet.ChannelData[0].Data.length + " of " + result.DataSet.DataPointsInFile);
        }
        else {
            $("#data-point-count").text(result.DataSet.ChannelData[0].Data.length);
        }

        // Format the data then generate the graphs
        var seriesData = [];
        for (var i = 0; i < result.DataSet.ChannelData.length; ++i) {
            var data = []
            for (var j = 0; j < result.DataSet.ChannelData[i].Data.length; ++j) {
                data[j] = { Time: new Date(FormatUtsDate(result.DataSet.ChannelData[i].Data[j].Time)), Value: result.DataSet.ChannelData[i].Data[j].Value }
            }

            seriesData[i] = {
                name: result.DataSet.ChannelData[i].Title !== "" ? result.DataSet.ChannelData[i].Title : result.DataSet.ChannelData[i].ChannelName,
                visibleInLegend: false,
                tooltip: {
                    template: "value: #= value.y #, time: #= FormatDate(value.x) #",
                    visible: true
                },
                type: "scatterLine",
                xField: "Time",
                yField: "Value",
                data: data,
                markers: {

                }
            }
        }

        $("#chart").kendoChart({
            series: seriesData,
            chartArea: {
                @* There is probably a better way to do this, but I can't think of it right now.
                This occurs before the divs are rendered so their widths at this point are not
                what they will be after rendering *@
                //width: 1074
            },
            xAxis: [{
                type: "date",
                baseUnit: "seconds",
                labels: {
                    step: (result.Columns == 3 ? 2 : 1)
                }
            }],
            yAxis: [{
                axisCrossingValue: [-50000]
            }],
            legend:{
                position: "left",
                orientation: "horizontal",
                visible: true
            },
            pannable: true,
            zoomable: true,
        });

        kendo.ui.progress($(".chart-loading"), false);
        $("#loading").hide();
        $("#nine-blocker-grid").show();
    }
    else {
        kendo.ui.progress($(".chart-loading"), false);
        $("#loading").hide();
        $("#error-message").text(response.Message);
        $("#error").show();
    }
});

All the series are being plotted, but for whatever reason the legend does not display. Just wonder if there is any obvious reason why that might be

Thanks

Hello Chris,

The legend will not be shown because the visibleInLegend option is set to false in the series configuration:

seriesData[i] = {
    name: result.DataSet.ChannelData[i].Title !== "" ? result.DataSet.ChannelData[i].Title : result.DataSet.ChannelData[i].ChannelName,
    visibleInLegend: false,
    ...

The dreaded pitfall of copy/paste.

Thanks for the help.
