I’m using highcharts as shown in examples but for some reason it flat out

  • 0

I’m using highcharts as shown in examples but for some reason it flat out does not like my data. The only time I see a result is when I zoom out to all and then it only shows one point. Any clues as to what I’m doing wrong would be extremely appreciated.

how im getting my data:

$jsResult = array();
$arResults = $wpdb->get_results("SELECT tsDay, nPrice FROM sometable", ARRAY_A);

    foreach($arResults as $key => $val){

        //$val['nPrice'] = floatval($val['nPrice']);

        //$jsResult[$key][0] = ($val['tsDay']*1000);
        //$jsResult[$key][1] = intval($val['nPrice']);

        //$strDate = date("Y/m/d", $val['tsDay']);
        //$strDate = explode('/', $strDate);

        $jsResult[$val['tsDay']] = '['.($val['tsDay']*1000).', '.$val['nPrice'].']';
    }

    $jsResult = "[\n".implode(",\n", $jsResult)."\n]";
    ?>

the chart:

$(document).ready(function() {

    var data = <?php echo $jsResult; ?>;

    // create the chart
    window.chart = new Highcharts.StockChart({
        chart : {
            renderTo : 'graph',
            zoomType: 'x'
        },

        navigator : {
            series : {
                data : data
            }
        },

        rangeSelector : {
            selected : 5 // All
        },

        tooltip: {
            xDateFormat: '%Y-%m-%d %H:%M:%S'
        },

        xAxis : {
            ordinal: true
        },

        series : [{
            //type: 'candlestick',
            name : 'data',
            data : data,
            dataGrouping : {
                enabled : false
            },
            marker: {
                enabled: true,
                radius: 2
            }
        }]
    });

    here is what’s wrong with your chart your array going backwords with time you start with jun 15 then 14 ,13 and so on

    if you use reverse() you will get an array looks like this 

        var data = [ [1337922000000,1569.50], [1338267600000,1579.50] ,
                 [1338354000000,1540.00],[1338440400000,1558.00],
                 [1338526800000,1606.00],
                 [1338958800000,1635.00],[1339045200000,1606.00],
                 [1339131600000,1576.50],[1339390800000,1584.00],
                 [1339477200000,1603.50],[1339563600000,1619.50],]
