Question

我有以下模型（下面的迁移）与访问我网站的国家/地区拉出图表。我怎样才能拔出前10个国家？谢谢

return Charts::database(Visit::all(), 'donut', 'highcharts')
        ->title('Requests by country')
        ->dimensions(700, 300)
        ->responsive(true)
        ->groupBy('country');

这是我的表

        $table->increments('id');
        $table->timestamp('timestamp');
        $table->ipAddress('ip_address');
        $table->string('city')->nullable();
        $table->string('country')->nullable();
        $table->string('details')->nullable();

Answer 1

按顺序使用

return Charts::database(Visit::all(), 'donut', 'highcharts')
        ->title('Requests by country')
        ->dimensions(700, 300)
        ->responsive(true)
        ->groupBy('country')
        ->orderBy('column_name','asc')  
        ->take(10);

Answer 2

尝试传递已经过滤的信息，如下所示：

$info = DB::table('visits')
       ->select(DB::raw('count(*) as country_count, country'))
       ->groupBy('country')
       ->orderBy('country_count', 'desc')
       ->take(10)
       ->get();

return Charts::database($info, 'donut', 'highcharts')
    ->title('Requests by country')
    ->dimensions(700, 300)
    ->responsive(true);

在Laravel中按国家/地区选择前5名
