谷歌折线图不使用 PHP 显示 MySQL 查询答案

【问题标题】：Google Line Chart not displaying MySQL query using PHP谷歌折线图不使用 PHP 显示 MySQL 查询

【问题描述】：

您好 StackOverflow 社区，我正在努力在 Google 折线图中使用 PHP 显示 MySQL 查询。问题是折线图没有显示。我会感谢任何能够为我指明正确方向的人。以下 MySQL 查询是我试图在折线图中表示的内容：

SELECT
    DATE(`VISIT_TIME`) AS `Date`,
    SUM(IF(HOUR(`VISIT_TIME`) = 0,
    1,
    0)) AS `TwelveAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 1,
    1,
    0)) AS `OneAM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 2,
    1,
    0)) AS `TwoAM`, 
    SUM(IF(HOUR(`VISIT_TIME`) = 3,
    1,

    SUM(IF(HOUR(`VISIT_TIME`) = 4,

    SUM(IF(HOUR(`VISIT_TIME`) = 5,

    SUM(IF(HOUR(`VISIT_TIME`) = 9,

    SUM(IF(HOUR(`VISIT_TIME`) = 10,

    SUM(IF(HOUR(`VISIT_TIME`) = 11,

    SUM(IF(HOUR(`VISIT_TIME`) = 14,

    SUM(IF(HOUR(`VISIT_TIME`) = 15,

    SUM(IF(HOUR(`VISIT_TIME`) = 18,
    1,
    0)) AS `SixPM`,
    SUM(IF(HOUR(`VISIT_TIME`) = 19,
    1,

    SUM(IF(HOUR(`VISIT_TIME`) = 20,

    SUM(IF(HOUR(`VISIT_TIME`) = 21,

    SUM(IF(HOUR(`VISIT_TIME`) = 22,

    SUM(IF(HOUR(`VISIT_TIME`) = 23,

以下查询显示过去 7 天每小时的请求数。

我希望在谷歌折线图中表示这些数据，如下图所示：

我为响应 DroopSnoot 所做的尝试：

我从 WhiteHat 的回答中得到的信息：

【问题讨论】：

您到底遇到了什么问题？
当我按照手册编写所有内容时，折线图未显示的问题。从逻辑上讲，它应该可以工作，我已经花了很多时间唉！无济于事。作为最后的手段，我来 StackOverflow。
不要尝试手动创建 JSON。在 PHP 中填充适当的数据结构，然后使用json_encode 创建适当的输出。
您能详细说明一下吗？我不确定 JSON 是不是问题。
到目前为止，您似乎还不确定问题出在哪里根本 - 所以至少将其排除为潜在的错误原因，但要以“正确的方式” ” 开始。

标签： php html mysql charts google-visualization

【解决方案1】：

这里有一些问题。

首先，列标题中有 25 个值...

['Date', 'TwelveAM', 'OneAM', 'TwoAM', ...

但行数据中有 26 个值...

echo "['".$result['Date']."',".$result['TwelveAM']."','".$result['OneAM']."' ...

有两个 TwelvePM 值，我们将在最后删除一个，
因为它与最后一列标题不匹配。

接下来，正如您在评论中提到的，
逗号和撇号的数量可能会令人困惑。
这是您不应尝试手动构建 JSON 的原因之一。

改为在 PHP 中构建数组，然后在写入页面时对 JSON 进行编码。

<?php
  $data = array();
  $data[] = ['Date', 'TwelveAM', 'OneAM', 'TwoAM', 'ThreeAM', 'FourAM', 'FiveAM', 'SixAM', '7AM', '8AM', '9AM', '10AM', '11AM', '12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM'];

  $fire = mysqli_query($connect, $sevenDaysHours);
  while($result = mysqli_fetch_assoc($fire))
  {
    $data[] = [$result['Date'], $result['TwelveAM'], $result['OneAM'], $result['TwoAM'], $result['ThreeAM'], $result['FourAM'], $result['FiveAM'], $result['SixAM'], $result['SevenAM'], $result['EightAM'], $result['NineAM'], $result['TenAM'], $result['ElevenAM'], $result['TwelvePM'], $result['OnePM'], $result['TwoPM'], $result['ThreePM'], $result['FourPM'], $result['FivePM'], $result['SixPM'], $result['SevenPM'], $result['EightPM'], $result['NinePM'], $result['TenPM'], $result['ElevenPM']];
  }
?>

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable(<?php echo json_encode($data); ?>);

  var options = {
    title: 'Company Performance',
    curveType: 'function',
    legend: { position: 'bottom' }
  };

  var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

  chart.draw(data, options);
}

这就是你要找的零件...

编辑

如果数值是 PHP 中的字符串，
然后尝试将JSON_NUMERIC_CHECK 参数添加到编码语句。

<?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>

让我们将 JSON 数据分配给它自己的变量。
然后我们可以将结果发送到控制台进行检查。
如果还是不行，请从控制台分享一个示例。

<?php
  $data = array();
  $data[] = ['Date', 'TwelveAM', 'OneAM', 'TwoAM', 'ThreeAM', 'FourAM', 'FiveAM', 'SixAM', '7AM', '8AM', '9AM', '10AM', '11AM', '12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM'];

  $fire = mysqli_query($connect, $sevenDaysHours);
  while($result = mysqli_fetch_assoc($fire))
  {
    $data[] = [$result['Date'], $result['TwelveAM'], $result['OneAM'], $result['TwoAM'], $result['ThreeAM'], $result['FourAM'], $result['FiveAM'], $result['SixAM'], $result['SevenAM'], $result['EightAM'], $result['NineAM'], $result['TenAM'], $result['ElevenAM'], $result['TwelvePM'], $result['OnePM'], $result['TwoPM'], $result['ThreePM'], $result['FourPM'], $result['FivePM'], $result['SixPM'], $result['SevenPM'], $result['EightPM'], $result['NinePM'], $result['TenPM'], $result['ElevenPM']];
  }
?>

var jsonData = <?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>;
console.log(JSON.stringify(jsonData));

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {

为了得到想要的图表，
我们需要将列交换为行，反之亦然。
这很可能很难通过更改查询来实现。
但是我们可以很容易地在 JavaScript 中创建一个新的数据表。

所以，几乎所有内容都保持不变。
除了我们将添加以下例程来创建一个新的数据表，
交换了列和行。
然后使用新的数据表绘制图表。

var jsonData = <?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>;

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable(jsonData);

  // create new data table with columns and rows swapped
  var dataHours = new google.visualization.DataTable();
  dataHours.addColumn('number', 'Hour');
  for (var row = 0; row < data.getNumberOfRows(); row++) {
    var dateColumn = dataHours.addColumn('number', data.getValue(row, 0));
    for (var col = 1; col < data.getNumberOfColumns(); col++) {
      var dateRow = dataHours.addRow();
      dataHours.setValue(dateRow, 0, col);
      dataHours.setValue(dateRow, dateColumn, data.getValue(row, col));
    }
  }

  var options = {
    title: 'Company Performance',
    curveType: 'function',
    legend: { position: 'bottom' }
  };

  var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

  chart.draw(dataHours, options);  // <-- draw chart with new data table
}

以下是一个工作示例，显示了交换之前和之后...

google.charts.load('current', {
  packages:['corechart']
}).then(function () {
  var data = google.visualization.arrayToDataTable([
    ['Date', 'TwelveAM', 'OneAM', 'TwoAM', 'ThreeAM', 'FourAM', 'FiveAM', 'SixAM', '7AM', '8AM', '9AM', '10AM', '11AM', '12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM'],
    ['2020-08-14', 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25],
    ['2020-08-15', 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50],
    ['2020-08-16', 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75],
    ['2020-08-17', 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100]
  ]);

  // create new data table with columns and rows swapped  
  var dataHours = new google.visualization.DataTable();
  dataHours.addColumn('number', 'Hour');
  for (var row = 0; row < data.getNumberOfRows(); row++) {
    var dateColumn = dataHours.addColumn('number', data.getValue(row, 0));
    for (var col = 1; col < data.getNumberOfColumns(); col++) {
      var dateRow = dataHours.addRow();
      dataHours.setValue(dateRow, 0, col);
      dataHours.setValue(dateRow, dateColumn, data.getValue(row, col));
    }
  }

  var options = {
    chartArea: {
      left: 64,
      top: 48,
      right: 32,
      bottom: 64,
      height: '100%',
      width: '100%'
    },
    height: '100%',
    legend: {
      alignment: 'center',
      position: 'bottom'
    },
    width: '100%'
  };

  var chartBefore = new google.visualization.LineChart(document.getElementById('chart_before'));
  chartBefore.draw(data, options);

  var chartAfter = new google.visualization.LineChart(document.getElementById('chart_after'));
  chartAfter.draw(dataHours, options);
});

.chart {
  height: 260px;
}

【讨论】：

希望这会有所帮助，如果它仍然不起作用。你需要在谷歌浏览器中按 F12 来打开开发工具。然后找到顶部的控制台选项卡，并提供以红色显示的任何消息。这些是错误...
非常感谢您的回答！我觉得我现在至少在某个地方。我在谷歌浏览器数据列中显示轴#0 不能是字符串类型×你知道是什么导致了这个消息吗？我不确定如何解决这个问题。
这意味着 y 轴的值来自 php 作为字符串，而不是数字。见上面的编辑，我们将数据分配给它自己的变量。然后我们可以发送到控制台进行检查。请分享控制台的结果示例。
嗨白帽！首先非常感谢您，现在终于可以使用了！然而，这不是我想象的图表的样子。我已经编辑了我的问题并附上了一张结果图片。我很抱歉继续下去，因为您对我的帮助非常大，是否可以进行调整，使其看起来和感觉就像我说的我希望它看起来像原来的图表？
这可能需要另一个问题，但让我们看一下。因此，您似乎希望 x 轴上的小时数和每个日期都是一个系列（线）。对吗？
