Question

我用它来绘制列高图jsfiddle 我用它来gt JSON：

<?php
    $query = mysql_query("SELECT
                                sales_raport_all.from_date,
                                sales_raport_all.to_date,
                                sales_raport_all.konto,
                                SUM(sales_raport_all.saldo_sprzedazy),
                                SUM(sales_raport_all.wartosc_kosztowa),
                                SUM(sales_raport_all.marza),
                                klienci_ax_all.sales_group,
                                klienci_ax_all.nazwa
                            FROM
                                sales_raport_all
                            INNER JOIN
                                klienci_ax_all
                            ON
                                sales_raport_all.konto=klienci_ax_all.konto_odbiorcy
                            WHERE
                                YEAR(from_date) = YEAR(CURDATE())
                            GROUP BY
                                sales_raport_all.from_date,
klienci_ax_all.sales_group
                            ORDER BY
                                sales_raport_all.from_date,
klienci_ax_all.sales_group");

$raw = array();
$dates = array();
while ($r = mysql_fetch_array($query)) {
$date = $r['from_date'];
if (!in_array($date, $dates)) $dates[] = $date;
$sales_group = $r['sales_group'];
$raw[$sales_group][$date] = intval($r['SUM(sales_raport_all.saldo_sprzedazy)']);
}
$data = array();
$data[0] = array('name' => "Date", 'data' => $dates);
foreach ($raw as $name => $d) {
$new_data = array('name' => $name, 'data' => array());
foreach ($dates as $date) {
    $new_data['data'][] = isset($d[$date]) ? $d[$date] : 0;
}
$data[] = $new_data;
}

print json_encode($data);

小提琴我用

chart3Options.series[0] = json[1];
...

有一种简单的方法来定义json中的所有数据吗？这个数据是可变的，如果我声明了11个变量，那么只有7个，那么图表就不会绘制一个日期的JSON输出：

[{"name":"Date","data":["2014-01-01"]},{"name":"IN","data":[2580]},{"name":"KD","data":[5030]},{"name":"\u0141S","data":[12628]},{"name":"NN","data":[400]},{"name":"SG","data":[12979]},{"name":"TD","data":[15096]}]

array_push($json,$result);

?>

JSON给我：

[{"name":["2014-01-01","2014-01-01","2014-01-01","2014-01-01","2014-01-01","2014-01-01"],"category":["IN","KD","\u0141S","NN","SG","TD"],"data":[2580,5030,12628,400,12979,15096]}]

系列看起来很棒，但我不知道如何更改类别，例如 http://jsfiddle.net/rubJS/

你可以在javascript中处理它。换句话说，不是为每个<x,y>对定义变量，而是返回数据并让javascript构建系列。例如，给定当前输出，您可以在单独的数组中准备X和Y值（在javascript中），并编写一个函数将这些值推送到系列中。它可以这样做（使用jQuery作为例子）：

function build_chart(x_values, y_values, options)
{
   jQuery.each(x_values, function(item) {
        options.xAxis.categories.push(x_values[item]);
    });

    var series = {
        data: []
    };

    jQuery.each(y_values, function(item) {
        series.data.push(parseInt(y_values[item]));
    });

    options.series.push(series);
    chart = new Highcharts.Chart(options);

    return chart;

}

变量options定义没有series成员的图表模板（由上述函数添加）

修改

在问题中进行编辑后，这里是jsFiddle支持它。请注意，JSON中的数据表示为数组数组。每个数组中的第一个元素对应于第一个类别，每个数组中的第二个元素对应于第二个类别等。

除了不正确的json格式（已被编辑）之外，您需要将日期作为高级图表中的分类或使用日期时间类型的轴，然后将日期解析为时间戳。
