Question

晚上好，晚上好。我有一个高亮图表，显示今年的所有月份。我想要的只是添加一个下拉列表月份，如果我选择一个月，图表将特别在下拉列表中选择的月份更改数据。请帮助我

继承我的data.php代码。此代码只会获取没有特定月份和年份的数据。现在我想要的是将月份下拉列表（例如1月 - 12月）与当前年份放在一起，如果我从下拉列表中选择一个月，则图表也会更改数据。

      <?php
$con = mysql_connect("localhost","root");

if (!$con) {
  die('Could not connect: ' . mysql_error());
}

    mysql_select_db("bfp", $con);

    $query = mysql_query("select city, sum(Miscellaneous) as Miscellaneous, 

sum(Residential) as Residential, sum(Assembly) as Assembly, sum(Educational) as `Educational, sum(Institutional) as Institutional, sum(Mercantile) as Mercantile,   sum(Business) as Business, sum(Industrial) as Industrial, sum(Storage) as Storage, sum(Mixed) as Mixed, sum(total) as total from report_structure group by city ");`

$category = array();
$category['name'] = 'City';

$series1 = array();
$series1['name'] = 'Business';

$series2 = array();
$series2['name'] = 'Storage';

$series3 = array();
$series3['name'] = 'Residential';

$series4 = array();
$series4['name'] = 'Assembly';

$series5 = array();
$series5['name'] = 'Educational';

$series6 = array();
$series6['name'] = 'Institutional';

$series7 = array();
$series7['name'] = 'Mercantile';

$series8 = array();
$series8['name'] = 'Industrial';

$series9 = array();
$series9['name'] = 'Miscellaneous';

$series10 = array();
$series10['name'] = 'Mixed';




while($r = mysql_fetch_array($query)) {
    $category['data'][] = $r['city'];
    $series1['data'][] = $r['Business'];
    $series2['data'][] = $r['Storage'];
    $series3['data'][] = $r['Residential'];
    $series4['data'][] = $r['Assembly'];
    $series5['data'][] = $r['Educational'];
    $series6['data'][] = $r['Institutional'];
    $series7['data'][] = $r['Mercantile'];
    $series8['data'][] = $r['Industrial'];
    $series9['data'][] = $r['Miscellaneous'];
    $series10['data'][] = $r['Mixed'];

}

$result = array();
array_push($result,$category);
array_push($result,$series1);
array_push($result,$series2);
array_push($result,$series3);
array_push($result,$series4);
array_push($result,$series5);
array_push($result,$series6);
array_push($result,$series7);
array_push($result,$series8);
array_push($result,$series9);

array_push($result,$series10);





print json_encode($result, JSON_NUMERIC_CHECK);

     mysql_close($con);
?>

结束data.php

这是我的structure.php数据加载。任何人都可以帮助我吗？

Answer 1

你可以用两种不同的方式来做。

将整个数据按月保存为单独的数据集。追加他们制作一整年的数据。当用户选择下拉列表中的任何月份时，更新系列数据或重新呈现图表
您可以对xAxis使用setExtremes（）方法，具体取决于下拉列表中选择的月份。

如果用户从6月1日到6月30日选择june set xAxis extremes。

希望这会对你有所帮助

通过在下拉列表中选择月份来获取高图更改图表
