我似乎无法完成此工作,我需要在图表上显示每天的总订单量。
我通过以下代码获得了开放的闪存图表:
<?php
// Settings for Database Connection
include_once($root_folder_path . "includes/common.php");
include_once("./admin_common.php");
include_once("./ofc_chart_library/open-flash-chart.php");
$sql = "SELECT * from orders ORDER BY order_placed_date";
if (!$sql) die('Invalid query: ' . mysql_error());
$result = mysql_query($sql);
$data = array();
while($row = mysql_fetch_array($result))
{
$data[] = intval($row['order_total']);
}
/*
* Create a title object and set the text to present month.
*/
$title = new title( 'Monthly Sales Statistics for ' . date("F Y") . ' (US Dollar)' );
$title->set_style( "{font-size: 18px; font-family: Calibri; color: #808000; text-align: center;}" );
//Make our Bar Chart
$bar = new bar_filled('#f99bd6', '#ee0099');
$bar->set_values($data);
//Create a new Chart object
$chart = new open_flash_chart();
// add the title to the chart:
$chart->set_title( $title );
$chart->set_bg_colour("#FFFFFF");
// Display the bar object on the chart
$chart->add_element($bar);
/*
* Create a Y Axis object
*/
$y_axis = new y_axis();
$y_axis->set_range(0, 12000, 1000);
// Add the y-axis object to the chart
$chart->add_y_axis($y_axis);
echo $chart->toPrettyString();
?>
现在上述代码很好,这是快照:

我想要的是显示X轴上的日期,从我的MySQL数据库中获取日期值。
以下是我的数据库中存储日期的方式,该数据库是DateTime类型:
2008-12-30 00:06:24
2009-02-03 01:57:17
2009-02-03 01:58:27
2009-05-03 01:58:48
2009-06-03 02:00:31
2009-07-03 02:01:47
2009-07-03 02:02:31
2009-07-04 14:21:18
2009-07-04 14:21:36
2009-07-04 14:22:18
2009-07-04 14:23:29
2009-07-04 14:24:24
我尝试了以下代码以在x轴中显示日期:
<?php
include_once 'php-ofc-library/open-flash-chart.php';
//Connect to MySQL Database
$con = mysql_connect("localhost", "root", "password");
if (!$con) die('Could not connect : ' . mysql_error());
$db_selected = mysql_select_db("cart",$con);
if (!db_selected) die ("Could not find the database: " . mysql_error());
$sql = "SELECT * from orders ORDER BY order_placed_date";
if (!$sql) die('Invalid query: ' . mysql_error());
$result = mysql_query($sql);
$amountData = array();
while($row = mysql_fetch_array($result))
{
$amountData[] = intval($row['order_total']);
}
$chart = new open_flash_chart();
$chart->set_title(new title('Open Flash Chart Downloads'));
//Make Bar Chart
$bar = new bar_filled('#df95c3', '#f34db7');
$bar->set_values($amountData);
//Create a new Chart object
$chart = new open_flash_chart();
/*
* Create a title object and set the text to present month.
*/
$title = new title( 'Monthly Sales Statistics for ' . date("F Y") . ' (US Dollar)' );
$title->set_style( "{font-size: 18px; font-family: Calibri; color: #808000; text-align: center;}" );
// add the title to the chart:
$chart->set_title( $title );
$chart->set_bg_colour("#FFFFFF");
// Add the bar object to the chart
$chart->add_element($bar);
//
// create an X Axis object
//
$x_axis = new x_axis();
// grid line and tick every 10
$x_axis->set_range(
mktime(0, 0, 0, 1, 1, date('Y')), // <-- min == 1st Jan, this year
mktime(0, 0, 0, 1, 31, date('Y')) // <-- max == 31st Jan, this year
);
// show ticks and grid lines for every day:
$x_axis->set_steps(86400);
$labels = new x_axis_labels();
// tell the labels to render the number as a date:
$labels->text('#date:d#');
// generate labels for every day
$labels->set_steps(86400);
// only display every other label (every other day)
$labels->visible_steps(1);
// finally attach the label definition to the x axis
$x_axis->set_labels($labels);
$y_axis = new y_axis();
$y_axis->set_range(0, 3000, 200);
// Display the Axis on the Chart
$chart->set_x_axis($x_axis);
$chart->add_y_axis($y_axis);
echo $chart->toPrettyString();
?>
这是我得到的:

该数量正在显示,但在0 x轴处有一行。
如何解决此问题,因此请从数据库中获取订单日期,然后根据下达订单的日期在图表上显示它们。
============================================================
以下是订单总计的JSON数据和放置日期。
<?php
include_once 'php-ofc-library/open-flash-chart.php';
//Connect to MySQL Database
$con = mysql_connect("localhost", "root", "password");
if (!$con) die('Could not connect : ' . mysql_error());
$db_selected = mysql_select_db("cart",$con);
if (!db_selected) die ("Could not find the database: " . mysql_error());
$sql = "SELECT * from orders ORDER BY order_placed_date";
if (!$sql) die('Invalid query: ' . mysql_error());
$result = mysql_query($sql);
$dateData = array();
$TotalAmountData = array();
while($row = mysql_fetch_array($result))
{
$TotalAmountData [] = intval($row['order_total']);
$dateData[] = $row['order_placed_date'];
}
print '<pre>';
print_r( $TotalAmountData );
print_r( $dateData );
print '</pre>';[/code]
?>
这显示了以下JSON数据:
Array // This is the Total Order Amount Per Day
(
[0] => 2499
[1] => 199
[2] => 449
[3] => 299
[4] => 359
[5] => 279
[6] => 1359
[7] => 5099
[8] => 2621
[9] => 2169
[10] => 2249
[11] => 5509
)
Array // This is the DateTime on which the orders where placed
(
[0] => 2008-12-30 00:06:24
[1] => 2009-02-03 01:57:17
[2] => 2009-02-03 01:58:27
[3] => 2009-05-03 01:58:48
[4] => 2009-06-03 02:00:31
[5] => 2009-07-03 02:01:47
[6] => 2009-07-03 02:02:31
[7] => 2009-07-04 14:21:18
[8] => 2009-07-04 14:21:36
[9] => 2009-07-04 14:22:18
[10] => 2009-07-04 14:23:29
[11] => 2009-07-04 14:24:24
)
我试图通过删除日期的时间来选择日期:
SELECT DATE_FORMAT(order_placed_date, '%m-%d-%Y'), order_total FROM orders
但是上面的代码显示了JSON数据的空值
更新:有人可以帮忙吗?
解决方案
您的价值观真的每天总计吗?看起来这是每订单的总总额,以及订单的日期。
您的第一个图的问题是,您不会将您的价值贴上每天的总计 - 打开闪存图不会为您做到这一点。您可以作为SQL查询的一部分执行此操作(例如使用 日期() 通过解析和重新格式化日期,将数据定为日期),或使用PHP转换为PHP,并在同一天添加值。请注意,根据您处理X轴的方式,您可能还需要在几天内添加0个条目,而无需任何订单。
第二个图的问题在于,您每秒设置一个元素,但是您的数据应为每天。这里重要的是要了解 线图和散点图之间的区别 在开放式闪存图中。使用一维数据点绘制线路图,而散点图则用坐标绘制。
