Question

我是highcharts和php的新手。我试图用数据库中的数据填充高图。我尝试播放代码以获得我想要的结果，但我总是失败。当我跑步时，我总是得到空白页面结果。

请帮帮我。我非常需要它。谢谢！

这是我的高图

$result1 = mysql_query($SQL1);
$data1 = array();
while ($row = mysql_fetch_array($result1)) {
   $data1[] = $row['name'];
   $data2[] = $row['Qty'];

}

                }
            }
        }]
    });
});

    </script>

<div id="container" style="min-width: 500px; height: 400px; margin: 0 auto"></div>

</body>
   </html>

这是我的数据库连接：

<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "pos";
$prefix = "";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not  connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");

?>

请尝试以下示例。我认为它可以帮到你

SQL表

CREATE TABLE IF NOT EXISTS `sales` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `month` varchar(200) DEFAULT NULL,
  `amount` varchar(11) DEFAULT NULL,
  PRIMARY KEY (`id`)

) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=118 ;


INSERT INTO `sales` (`id`, `month`, `amount`) VALUES
(24, 'Apr', '15'),
(25, 'May', '40'),
(26, 'Jun', '26'),
(27, 'Jul', '31'),
(28, 'Aug', '39'),
(29, 'Sep', '25'),
(30, 'Oct', '27'),
(31, 'Nov', ' 32'),
(32, 'Dec', NULL);

这里我们创建新表并在其中插入一些数据。现在数据将如下所示

Table

                    }
                }
   }],
        }

        //Fetch MySql Records
        jQuery.get('js/data.php', null, function(tsv) {
   var lines = [];
   traffic = [];
   try {
    // split the data return into lines and parse them
    tsv = tsv.split(/\n/g);
    jQuery.each(tsv, function(i, line) {
     line = line.split(/\t/);
     date = line[0] ;
                                        amo=parseFloat(line[1].replace(',', ''));
                                        if (isNaN(amo)) {
                                                   amo = null;
                                        }
     traffic.push([
      date,
      amo
     ]);
    });
   } catch (e) {  }
   cursan.series[0].data = traffic;
   chart = new Highcharts.Chart(cursan);
  });
 });

js将从data.php的mysql导入数据并添加到以前在js中创建的图表。

<强> data.php

$con=mysql_connect('localhost','root','');
mysql_select_db("test", $con);
$result=mysql_query('select * from sales order by id');
while($row = mysql_fetch_array($result)) {
  echo $row['month'] . "\t" . $row['amount']. "\n";
}

我们的图表已满载。使用mysql记录，输出将显示在下面

<强>输出 Output

区域图的示例，您可以通过更改defaultSeriesType: 'area'

来更改图表类型

Answer 2

确保您拥有data格式的x,y for highchart

data = [{x:1,y:4500},{x:2,y:20}]

<强> FIDDLE

Answer 3

在这个系列中你有类似的东西

['<?php echo join($data2, "','"); ?>']

这意味着在数组的第一个元素中你有字符串，所以不调用php。我通过文章http://www.highcharts.com/docs/working-with-data/data-intro向familair提出建议。我建议使用json_encode，它允许sto返回json，然后在没有加入/解析的情况下进入javascript。
