【问题描述】：
我正在尝试使用 fusioncharts 创建图表，我正在使用 AJAX 查询来获取数据，下面是我生成图表的方式。
我的问题是融合图表需要查看例如“值”：“1”，因为我需要能够使用“0”：“1”，因为下面是我的 php
我的 PHP 脚本获取昨天和今天每个小时的登录信息
$yesterdays_date = new datetime(date('d.m.Y',strtotime("-1 days")));
$query = "SELECT DATE(login_date) as date, HOUR(login_date) as hour, COUNT(*) as logins FROM logins WHERE login_date >= '".$yesterdays_date->format('Y-m-d')."' GROUP BY DATE(login_date), HOUR(login_date)";
//storing the result of the executed query
$result = $conn->query($query);
//initialize the array to store the processed data
$jsonArray = array();
$array = array(
'today' => array(
"seriesname" => "Logins Yesterday",
"data" => array(
'0' => 0,
'1' => 0,
'2' => 0,
'3' => 0,
'4' => 0,
'5' => 0,
'6' => 0,
'7' => 0,
'8' => 0,
'9' => 0,
'10' => 0,
'11' => 0,
'12' => 0,
'13' => 0,
'14' => 0,
'15' => 0,
'16' => 0,
'17' => 0,
'18' => 0,
'19' => 0,
'20' => 0,
'21' => 0,
'22' => 0,
'23' => 0,
),
),
'yesterday' => array(
"seriesname" => "Logins Today",
"renderAs" => "line",
"showValues" => "0",
"data" => array(
'0' => 0,
'1' => 0,
'2' => 0,
'3' => 0,
'4' => 0,
'5' => 0,
'6' => 0,
'7' => 0,
'8' => 0,
'9' => 0,
'10' => 0,
'11' => 0,
'12' => 0,
'13' => 0,
'14' => 0,
'15' => 0,
'16' => 0,
'17' => 0,
'18' => 0,
'19' => 0,
'20' => 0,
'21' => 0,
'22' => 0,
'23' => 0,
),
),
);
//check if there is any data returned by the SQL Query
if ($result->num_rows > 0) {
//Converting the results into an associative array
while($row = $result->fetch_assoc()) {
if($row['date'] == $yesterdays_date->format('Y-m-d')){
//- Yesterdays data
$array['yesterday']['data'][$row['hour']] = $row['logins'];
}else{
//- Todays data
$array['today']['data'][$row['hour']] = $row['logins'];
}
//$jsonArrayItem = array();
//$jsonArrayItem['date'] = $row['date'];
//$jsonArrayItem['hour'] = $row['hour'];
//$jsonArrayItem['logins'] = $row['logins'];
//append the above created object into the main array.
//array_push($jsonArray, $jsonArrayItem);
}
}
//set the response content type as JSON
header('Content-type: application/json');
//output the return value of json encode using the echo function.
echo json_encode($array);.
我从 PHP 脚本返回的数据
我的 jQuery 来生成昨天和今天的登录比较图表
function getLogins(){
$.ajax({
url: '/ajax/getLoginsToday.php',
type: 'GET',
success: function(data){
var chartProperties = {

apiChart = new FusionCharts({

}
],
"dataset": [

{

"renderAs": "line",

},
{

}
]
}
]
}
});
apiChart.render();
}
});
}
在我上面的 jQuery AJAX 成功块中，您可以看到我正在尝试通过 AJAX 数据设置数据集，但 fusioncharts 需要将其视为“值”：“1” 而我的数据格式为“0”：“1”，“23”：“4”。
将其转换为 fusioncharts 所需格式的最佳解决方案是什么？
