我正在使用示例中所示的 highcharts,但由于某种原因,它完全不喜欢我的数据。我看到结果的唯一一次是当我缩小到全部然后它只显示一个点。关于我做错了什么的任何线索将不胜感激。
我如何获取我的数据:
$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]";
?>
图表:
$(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
}
}]
});
来自 Highcharts 的样本数据绘制得很好:
