从数据库中取出最近三十天的数据并生成柱状图

在终端用cd 命令进入文件目录
说明：此处例子我是拿项目中的一个例子讲解的。
1、新建一个项目 ：用终端输入：zf create project Airline 格式：zf create action project project-name 备注：这些格式可以在终端输入zf 查看
2、新建一个action ：zf create action dirgramshow index 格式：zf create action action-name controller-name
3、新建一个 model ：zf create db-table flightinformation
action 层代码：indexController.php


代码如下:

public function indexAction ()
{
// action body
$db = new Application_Model_DbTable_Flightinformation();
/*获取最近30天内的数目
* select day(boo_time) as day,count(boo_autoid)as count,boo_time from bookinformation
where flag_pass=0 and date_sub(now(), interval 30 day)<=date(boo_time)
group by DATE_FORMAT(boo_time,'%m %d')
*/
$sql = "select DATE_FORMAT(boo_time,'%m-%d') as day,count(boo_autoid)as count from bookinformation " .
"where flag_pass=0 and date_sub(now(), interval 30 day)<=date(boo_time) " .
"group by DATE_FORMAT(boo_time,'%m %d')";
$result = $db->getAllInfo($sql)->fetchAll();
$this->view->result=$result;
}

view 层代码：dirgramshow.phtml


代码如下:

<?php

color.push('#2D6B96');
<?php
}
?>
if(d!=""){

var myData = d;
var colors =color;
var myChart = new JSChart('graph', 'bar');
myChart.setDataArray(myData);
myChart.colorizeBars(colors);
myChart.setTitle('Airline diagram');
myChart.setTitleColor('#8E8E8E');
myChart.setAxisNameX('');
myChart.setAxisNameY('');
myChart.setAxisColor('#C4C4C4');
myChart.setAxisNameFontSize(16);
myChart.setAxisNameColor('#999');
myChart.setAxisValuesColor('#777');
myChart.setAxisColor('#B5B5B5');
myChart.setAxisWidth(1);
myChart.setBarValuesColor('#2F6D99');
myChart.setBarOpacity(0.5);
myChart.setAxisPaddingTop(60);
myChart.setAxisPaddingBottom(40);
myChart.setAxisPaddingLeft(45);
myChart.setTitleFontSize(11);
myChart.setBarBorderWidth(0);
myChart.setBarSpacingRatio(50);
myChart.setBarOpacity(0.9);
myChart.setFlagRadius(6);
myChart.setTooltip(['North America', 'U.S.A and Canada']);
myChart.setTooltipPosition('nw');
myChart.setTooltipOffset(3);
myChart.setSize(616, 321);
/*myChart.setBackgroundImage('<?php
//echo $this->baseUrl() . '/skin/image/ZJPchart_bg.jpg'?>');*/
myChart.draw();
}
</script>
</body>
</html>

model 层代码：Flightinformation.php


代码如下:

<?php
class Application_Model_DbTable_Flightinformation extends Zend_Db_Table_Abstract
{
protected $_name = 'flightinformation';
public function getAllInfo($sql){
$adapter = Zend_Registry::get('db');
$flightinformation = $adapter->query($sql);
return $flightinformation;
}
}

最后的效果图如下：

if ($ != jQuery) {
$ = jQuery.noConflict();
}
var isLogined = false;
var cb_blogId = 68465;
var cb_entryId = 2025928;
var cb_blogApp = "hailiang";
var cb_blogUserGuid = "52dd1425-7333-df11-ba8f-001cf0cd104b";
var cb_entryCreatedDate = '2011/4/23 22:49:00';
