我正在尝试使用 php 和 mySQL创建highstock的烛台图。
到目前为止,这是我的代码,如果有人可以帮助我,非常感谢:
这是我从 mySQL 数据库中检索数据并将其转换为 JSON 格式(datachart.php)的代码:
$conn = mysql_connect("localhost", "root", "") or die (mysql_error ());
$db = mysql_select_db ("b27sim") or die (mysql_error ());
$result=mysql_query ("SELECT date, open, high, low, close FROM mb27_daily") or die (mysql_error ());
$data = array();
$count = 0;
while ($row=mysql_fetch_array($result))
{
$newdate = strtotime($row['date']) * 1000;
$data[] = array( $newdate, (float)$row['open'], (float)$row['high'], (float)$row['low'], (float)$row['close']);
$count++;
}
echo json_encode($data);
这是 datachart.php 的结果:
[[1350252000000,369.72,371.02,368.09,370.22],[1349820000000,366.58,369.13,364.92,368.92],[1349733600000,367.38,369.93,366.82,368.64],[1349388000000,367.28,371.85,367.2,369.9],[ 1349301600000,362.75,366.24,362.22,365.61],[1349215200000,363.34,363.54,361.27,362.27],[1349128800000,360.79,362.73,360.33,361.77],[1349042400000,360.75,360.75,357.94,359.46],[1348783200000, 360.62,362.69,359.84,362.5],[1348696800000,356.39,361.01,355.32,359.34],[1348524000000,358,360.39,356.34,359.7],[1348437600000,357.96,360.99,355.92,356.89],[1348178400000,359.27,360.53, 356.93,360.53],[1348092000000,358.74,359.31,356.51,358.01],[1348005600000,357.97,361.82,357.24,359.86],[1347919200000,359.8,360.34,356.78,358.5],[1233010800000,119.28,122.42,119.28, 121.91]]
这是我在 index.htm 中的 javascript 代码:
$(function() {
$.getJSON('datachart.php', function(data) {
// create the chart
chart = new Highcharts.StockChart({
chart : {
renderTo : 'container',
},
rangeSelector : {
selected : 1
},
title : {
text : 'IB27 Price'
},
series : [{
type : 'candlestick',
name : '',
data : data,
tooltip: {
valueDecimals: 2
},
dataGrouping : {
units : [
['week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]]
]
}
}]
});
});
});
这是我调用容器的 div:
<div id="container" style="height: 500px; min-width: 500px"></div>
这就是结果:我得到的内部没有图表,但在底部显示时间线,在右上角显示日期范围等。
感谢你们在这方面的帮助,因为我在过去的 4 个小时里一直在敲我的头,因为这个...... :)
谢谢,拉兹
