我使用 JavaScript (PHP) 中的 Chartist.js 库创建了图表以图形形式显示值。 Y 轴的所有值均来自数据库。但我无法以千位分组格式显示 Y 轴。我想在交叉点的工具提示上显示千格式值(检查图像)

PHP代码

$clientData = $wpdb->get_results('SELECT * FROM clientsdata WHERE Client_Id = "'.$currentUser->ID.'"');
$months=array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
$selectedFieldData = array();
foreach($months as $month){ 
$value = '';
    foreach($clientData as $client){
        if($client->Month == $month && $client->Year == $selectYear){
            $value = $client->$fieldValue;
            break;
        }
    }
    if(!empty($value)){ 
            $selectedFieldData[] = $value; //See below - 1
        }
        else{
            $selectedFieldData[] = null;
        }
}

JavaScript代码(图实际代码)

1 - 如果我在这里使用 number_format，那么它会将值转换为千格式，但是数组在单独的位置获取值，因此实际值会中断。

谁能尝试解决这个问题？

最佳答案

最后，我的一位 friend 解决了这个问题。

1. 由 Jquery 修复 - 图中 Y 轴上以千为单位的数字。 工具提示上按“货币 :' '”固定的千位数字。

这是完整的代码。 PHP代码

$clientData = $wpdb->get_results('SELECT * FROM clientsdata WHERE Client_Id = "'.$currentUser->ID.'"');
$months=array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
$selectedFieldData = array();
foreach($months as $month){ 
$value = '';
    foreach($clientData as $client){
        if($client->Month == $month && $client->Year == $selectYear){
            $value = $client->$fieldValue;
            break;
        }
    }
    if(!empty($value)){ 
            $selectedFieldData[] = $value;
        }
        else{
            $selectedFieldData[] = null;
        }
}
