  • Chart doesn't render if same values #15015

    Dear all,

    In my line chart, if the values are the same, I got a

    “Problem parsing d=”M 30,NaN L 30,NaN 30,NaN 133.5,NaN 238.5,NaN 343.5,NaN 448.5,NaN 553.5,NaN 658.5,NaN 763.5,NaN 868.5,NaN 973.5,NaN”

    If there is 1 different value, the chart renders fine.

    Here is the Json i’m using :

    [{“Id”:0,”Date”:”\/Date(1360593014540)\/”,”Value”:”22.50″},{“Id”:1,”Date”:”\/Date(1360593016590)\/”,”Value”:”22.50″},{“Id”:2,”Date”:”\/Date(1360593018487)\/”,”Value”:”22.50″},{“Id”:3,”Date”:”\/Date(1360593020103)\/”,”Value”:”22.50″},{“Id”:4,”Date”:”\/Date(1360593021733)\/”,”Value”:”22.50″},{“Id”:5,”Date”:”\/Date(1360593023347)\/”,”Value”:”22.50″},{“Id”:6,”Date”:”\/Date(1360593025150)\/”,”Value”:”22.50″},{“Id”:7,”Date”:”\/Date(1360593026713)\/”,”Value”:”22.50″},{“Id”:8,”Date”:”\/Date(1360593028370)\/”,”Value”:”22.50″},{“Id”:9,”Date”:”\/Date(1360593030223)\/”,”Value”:”22.50″}]

    And the settings of the chart :

    var settings = {
    title: "Historique des températures",
    description: "",
    source: dataAdapter,
    colorScheme: 'scheme01',
    showLegend: false,
    categoryAxis: {
    displayValueAxis: true,
    dataField: 'Date',
    axisSize: 'auto',
    showGridLines: false,
    unitInterval: unitInterval,
    description: 'Temps',
    formatFunction: function (value) {
    var date = new Date(value);
    return '[' + Digits2(date.getDate()) + ']' + Digits2(date.getHours()) + ':' + Digits2(date.getMinutes()) + ':' + Digits2(date.getSeconds());
    },
    },
    seriesGroups: [{
    type: 'line', // change the series type here
    valueAxis: {
    axisSize: 'auto',
    description: 'Value'
    },
    series: [{ dataField: 'Value', displayText: 'temp' }]
    }]
    };

    If you have an idea how to fix that ?
