在后台的数据统计之中经常会使用到趋势图和数据统计图，下面就结合GOOGLE开发者上面的GoogChart类来整合了两种类型的统计图。
1、饼状图：
/** * @todo 饼状图 * @param $title 饼状图标题 * @param $color 饼状图的颜色范围 * @param $data 饼状图展示数据 * @return $url 饼状图生成后的URL地址 * @example * // Set graph data $data = array( ‘IE7‘ => 22, ‘IE6‘ => 30.7, ‘IE5‘ => 1.7, ‘Firefox‘ => 36.5, ‘Mozilla‘ => 1.1, ‘Safari‘ => 2, ‘Opera‘ => 1.4, ); // Set graph colors $color = array( ‘#99C754‘, ‘#54C7C5‘, ‘#999999‘, ); // Set graph title $title=‘浏览器使用统计‘; */ public function pieChart($title,$color,$data){ $chartPath=Yii::app() -> request -> baseUrl.‘/protected/extensions/chart/‘; include($chartPath.‘GoogChart.class.php‘); $chart=new GoogChart(); $chart->setChartAttrs( array( ‘type‘ => ‘pie‘, ‘title‘ => $title, ‘data‘ => $data, ‘size‘ => array( 400, 300 ), ‘color‘ => $color ) ); return $chart; }
2、走势图
/** * @todo 走势图 * @param $title 走势图标题 * @param $color 走势图每条线的颜色范围 * @param $data 走势图的数据 * @return $url 走势图生成后的URL地址 * @example * // Set graph data $data = array( ‘2007‘ => array( ‘January‘ => 31.0, ‘February‘ => 31.2, ‘March‘ => 31.8, ‘April‘ => 32.9, ‘May‘ => 33.7, ‘June‘ => 34.0, ‘July‘ => 34.5, ‘August‘ => 34.9, ‘September‘ => 35.4, ‘Oktober‘ => 36.0, ‘November‘ => 36.3, ‘December‘ => 36.3, ), ‘2006‘ => array( ‘January‘ => 25.0, ‘February‘ => 24.5, ‘March‘ => 24.5, ‘April‘ => 22.9, ‘May‘ => 22.9, ‘June‘ => 25.5, ‘July‘ => 25.5, ‘August‘ => 24.9, ‘September‘ => 27.3, ‘Oktober‘ => 27.3, ‘November‘ => 29.9, ‘December‘ => 29.9, ), ‘2005‘ => array( ‘January‘ => 15.0, ‘February‘ => 14.5, ‘March‘ => 14.5, ‘April‘ => 12.9, ‘May‘ => 12.9, ‘June‘ => 15.5, ‘July‘ => 15.5, ‘August‘ => 14.9, ‘September‘ => 17.3, ‘Oktober‘ => 17.3, ‘November‘ => 19.9, ‘December‘ => 19.9, ), ); // Set graph colors $color = array( ‘#99C754‘, ‘#54C7C5‘, ‘#999999‘, ); // Set graph title $title=‘浏览器使用统计‘; */ public function sparkLineChart($title, $color, $data){ $chartPath=Yii::app() -> request -> baseUrl.‘/protected/extensions/chart/‘; include($chartPath.‘GoogChart.class.php‘); $chart=new GoogChart(); $chart->setChartAttrs( array( ‘type‘ => ‘sparkline‘, ‘title‘ => $title, ‘data‘ => $data, ‘size‘ => array( 600, 200 ), ‘color‘ => $color, ‘labelsXY‘ => true, ‘fill‘ => array( ‘#f0f0f0‘, ‘#cccccc‘ ), ) ); return $chart; }
简单的几段代码就可以实现后台数据统计。
