pChart是一个开源的图表生成库,主要涉及3个Class:pChart.class, pData.class, pCache.class,可生成20多种简单或复杂的图表,支持PNG,JPG,GIF通用图片格式。数据源可以来自于Database,CSV,当然也可以手写。使用该程序PHP需要开启GD服务,先来看看pChart的工作流程:
主要分为三步:
- * 读取用于生成图表数据(数据库、文件)
- * 设计图表样式(圆角、底色等)
- * 制作标签、题目、图例并生成图表
下面看一个简单的柱状图表:
代码如下:
<"pChart/pData.class"); include("pChart/pChart.class"); // Dataset definition $DataSet = new pData; //图表数据 $DataSet->AddPoint(array(1,4,-3,2,-3,3,2,1,0,7,4),"Serie1"); $DataSet->AddPoint(array(3,3,-4,1,-2,2,1,0,-1,6,3),"Serie2"); $DataSet->AddPoint(array(4,1,2,-1,-4,-2,3,2,1,2,2),"Serie3"); $DataSet->AddAllSeries(); $DataSet->SetAbsciseLabelSerie(); //数据图例 $DataSet->SetSerieName("Microsoft","Serie1"); $DataSet->SetSerieName("IBM","Serie2"); $DataSet->SetSerieName("Google","Serie3"); // Initialise the graph $Test = new pChart(700,230); //设置图表尺寸、样式 $Test->setFontProperties("Fonts/tahoma.ttf",8); $Test->setGraphArea(50,30,680,200); $Test->drawFilledRoundedRectangle(7,7,693,223,5,240,240,240); $Test->drawRoundedRectangle(5,5,695,225,5,230,230,230); $Test->drawGraphArea(255,255,255,TRUE); $Test->drawScale($DataSet->GetData(),$DataSet->GetDataDescription(),SCALE_NORMAL,150,150,150,TRUE,0,2,TRUE); $Test->drawGrid(4,TRUE,230,230,230,50); // Draw the 0 line $Test->setFontProperties("Fonts/MankSans.ttf",6); $Test->drawTreshold(0,143,55,72,TRUE,TRUE); // Draw the bar graph //柱状图要使用drawBarGraph() $Test->drawBarGraph($DataSet->GetData(),$DataSet->GetDataDescription(),TRUE,80); // Finish the graph //制作图例、标题、字体等属性 $Test->setFontProperties("Fonts/MankSans.ttf",10); $Test->drawLegend(596,150,$DataSet->GetDataDescription(),255,255,255); $Test->setFontProperties("Fonts/MankSans.ttf",10); $Test->drawTitle(50,22,"Example",50,50,50,585); //生成图表 $imageFile = "example12.png"; $Test->Render($imageFile); echo '<img src="/UploadFiles/2021-04-02/'.$imageFile.'">代码:
<"pChart/pData.class"); include("pChart/pChart.class"); // Dataset definition $DataSet = new pData; $DataSet->AddPoint(array("Memory","Disk","Network","Slots","CPU"),"Label"); $DataSet->AddPoint(array(6,4,7,4,5),"Serie1"); $DataSet->AddPoint(array(2,3,5,2,4),"Serie2"); $DataSet->AddSerie("Serie1"); $DataSet->AddSerie("Serie2"); $DataSet->SetAbsciseLabelSerie("Label"); $DataSet->SetSerieName("Reference","Serie1"); $DataSet->SetSerieName("Tested computer","Serie2"); // Initialise the graph $Test = new pChart(400,400); $Test->setFontProperties("Fonts/tahoma.ttf",8); $Test->drawFilledRoundedRectangle(7,7,393,393,5,240,240,240); $Test->drawRoundedRectangle(5,5,395,395,5,230,230,230); $Test->setGraphArea(30,30,370,370); $Test->drawFilledRoundedRectangle(30,30,370,370,5,255,255,255); $Test->drawRoundedRectangle(30,30,370,370,5,220,220,220); // Draw the radar graph //要使用drawRadarAxis()生成雷达效果 $Test->drawRadarAxis($DataSet->GetData(),$DataSet->GetDataDescription(),TRUE,20,120,120,120,230,230,230); $Test->drawFilledRadar($DataSet->GetData(),$DataSet->GetDataDescription(),50,20); // Finish the graph $Test->drawLegend(15,15,$DataSet->GetDataDescription(),255,255,255); $Test->setFontProperties("Fonts/tahoma.ttf",10); $Test->drawTitle(0,22,"Example",50,50,50,400); $imageFile = "example8.png"; $Test->Render($imageFile); echo '<img src="/UploadFiles/2021-04-02/'.$imageFile.'">2, 双座标曲线图:
3, 层叠柱状图:
4, 多图表:
图表的种类已经相当丰富了,具体图表设置请参考

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
