我需要你对这个项目的建议,我试图用 MS SQL Server 数据库中的 php 提供一个像这样的“组合”谷歌图表。
我已经构建了以下视图,它为我提供了相关数据。稍后我将不得不为每个项目创建一系列这些图表(通过“ProjectUniqueId”标识)。
从到目前为止我得到的所有文档中,我了解到我必须以编程方式构建以下数据表
var data = google.visualization.arrayToDataTable([
['Week', 'Hrs VSE', 'Hrs PII', 'Hrs VDG', 'Hrs PIA', 'Hrs TCIS', 'Forecast' ],
['2013-W20', 165, 938, 522, 998, 450, 614.6],
['2013-W21', 135, 1120, 599, 1268, 288, 682],
['2013-W22', 157, 1167, 587, 807, 397, 1200],
['2013-W23', 139, 1110, 615, 968, 215, 2000],
['2013-W24', 136, 691, 629, 1026, 366, 569.5]
]);
作为此页面的一部分:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['corechart']});
</script>
<script type="text/javascript">
function drawVisualization() {
//Raw data
var data = google.visualization.arrayToDataTable([
['Week', 'Hrs VSE', 'Hrs PII', 'Hrs VDG', 'Hrs PIA', 'Hrs TCIS', 'Forecast' ],
['2013-W20', 165, 938, 522, 998, 450, 614.6],
['2013-W21', 135, 1120, 599, 1268, 288, 682],
['2013-W22', 157, 1167, 587, 807, 397, 1200],
['2013-W23', 139, 1110, 615, 968, 215, 2000],
['2013-W24', 136, 691, 629, 1026, 366, 569.5]
]);
var options = {
title : 'Actuals vs Forecast VLU Project per Cost-Center',
vAxis: {title: ""},
//Horizontal axis text vertical
hAxis: {title: "", slantedText:true, slantedTextAngle:90},
seriesType: "bars",
series: {5: {type: "line"}},
isStacked: true
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
google.setOnLoadCallback(drawVisualization);
</script>
我首先尝试手动构建dataTable(我将其理解为数组的“组装”)
1)构建“列标题”数组(CcName)
2)构建“行标题”数组(WeekValue)
3) 查询 (HoursValue) 特定 WeekValue,CcName 的每个单独值 ...
最后,我从未真正设法构建所需的数组,然后找到有关 JSON 的文档以及它如何提供帮助,但没有设法在我的代码中实现它。
<?php
$myServer = "XXXXXX";
$myUser = "reportuser";
$myPass = "";
$myDB = "HOURS";
//Connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");
//Select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
or die("Couldn't open database $myDB");
//Declare the SQL statement that will query the database
$query = "SELECT CcName, WeekValue, SUM(HoursValue) AS HoursValue FROM viewFunctionalHoursKpi WHERE Approval='Actuals' AND ProjectUniqueId=1286 GROUP BY CcName, WeekValue";
//Execute the SQL query and return records
$result = mssql_query($query)
or die('An error occured: ' . mysql_error());
$resultArray = array();
while ($record = mssql_fetch_array($result))
{
//Fill array
$resultArray[] = $record;
}
//Output in JSON format
echo json_encode($resultArray);
//Free result set memory
mssql_free_result($result);
//Close the connection
mssql_close($dbhandle);
?>
你们有什么建议?我绝对愿意通过更改我在 MS SQL Server 中获得的当前视图来更改数据的格式,但对我来说最困难的是如何将我从 php 获得的数据传输到这个 js dataTable(如果这是方法)。
谢谢你的帮助!
