效果图:

原代码如下:

var ImageName;//报表名称
var ImageType;//报表类型

var ImageWidth;//图片宽
var ImageHeight;//图片高


var BgImage;//背景图片
var BgR;//背景颜色R值
var BgG;//背景颜色G值
var BgB;//背景颜色B值

var FontSize;//字体大小
var FontColor;//字体颜色

var ItemArray;//数据数组
var ItemInterval;//两项间的间隔
var XName;//x轴的名称
var YName;//y轴的名称
var isScale;//是否显示刻度值
var margin;//边距

//字体
var font = 'arial.ttf';

report->setItem(temparray,interval,XName,YName,isScale);//参数(数组,间隔,X轴文字,Y轴文字,背景图片)
report->setBg(BgR,BgG,BgB,"logo.jpg");//参数(背景颜色)
report->setFont(10);//字体大小1-10
report->drawReport();
report->showImage("../images/report/".id.".png");//参数为保存的路径
