Question

我正在Laravel中创建一个图表。它显示年度数据。我也想使用选择按钮显示每周，每月。如何分离数据？

    <script>

        var chartData = new Array();
        @foreach($monthlyVisits as $key => $val)
            chartData.push('<?php echo $val; ?>');
        @endforeach

        var barData = {
            labels: ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"],
            datasets: [{
                label: "Total Number of Visits",
                backgroundColor: 'rgba(26,179,148,0.5)',
                borderColor: "rgba(26,179,148,0.7)",
                pointBackgroundColor: "rgba(26,179,148,1)",
                pointBorderColor: "#fff",
                 // data: [ 150, 48, 40, 19, 86, 27, 90, 100, 75, 50, 60, 90]
                data: chartData
            }]
        };
        var barOptions = {
            responsive: true
        };
        var ctx2 = document.getElementById("barChart").getContext("2d");
        new Chart(ctx2, {
            type: 'bar',
            data: barData,
            options: barOptions
        });

        var polarData = {
            datasets: [{
                data: [
                    300, 140, 200
                ],
                backgroundColor: [
                    "#a3e1d4", "#dedede", "#b5b8cf"
                ],
                label: [
                    "My Radar chart"
                ]
            }],
            labels: [
                "App", "Software", "Laptop"
            ]
        };
    </script>

对于每月访问，您的查询应类似于：

    public function getMonthlyVisits()
    {
        $monthlyVisitors = DB::table('shorteners')
            ->select([
                DB::raw('MONTH(created_at) as month'),
                DB::raw('count(total_visits as total_visits'),
            ])
            ->groupBy('month')
            ->get();
    }

对于年度访问：

    public function getYearlyVisits()
    {
        $monthlyVisitors = DB::table('shorteners')
            ->select([
                DB::raw('YEAR(created_at) as year'),
                DB::raw('count(total_visits as total_visits'),
            ])
            ->groupBy('year')
            ->get();
    }

每周访问：

    public function getWeeklyVisits()
    {
        $monthlyVisitors = DB::table('shorteners')
            ->select([
                DB::raw('WEEK(created_at) as week'),
                DB::raw('count(total_visits as total_visits'),
            ])
            ->groupBy('week')
            ->get();
    }
