http://202.109.105.148:31415/verifycode/buildchart.aspx?charttype=1如需要2D效果，则相应增加if3D=false

Answer 1

另外还有一种是点图，由于相对简单，就没有列出来
charttype=4

Answer 2

就是用C#使用GDI+函数做的，并不复杂，画完坐标系再画坐标，然后再画线或矩形等各种形状即可

czhenq(挨饿中……) ,能看一下你做的成果么？

Answer 5

good!
我有个问题:
http://community.csdn.net/Expert/topic/3553/3553456.xml?temp=.376034

Answer 6

怎么个做法，用在winform可不可以（要求打印）

Answer 7

可以，用在winform下，只要使用Stream就可以了，可以将图片直接显示在窗体上

Answer 8

在 winform里面调用如下：是MemoryStream
psLibBase.ClsBuildChart tmp = new psLibBase.ClsBuildChart();
tmp.ChartNameSize=11;
tmp.fontFamily="宋体";
tmp.chartYBuffer=40;
tmp.XYSize=9;

MemoryStream stmp = tmp.MakePieChart("红色,橙色,黄色,绿色,兰色,紫色,颜色一,颜色二,颜色三,testPie,color4,color5,color6"
,"10,20,15,8,11,15,25,8,8,18,10,5,15"
,"测试"
,450
,320);
Image frmimage = new Bitmap(stmp);
pictureBox1.Width=450;
pictureBox1.Height=320;
pictureBox1.Image = frmimage;

Answer 9

psLibBase是你的做的类吧,那在一个图中如何用到两种表示方法呢.我的需求是最后要打印出来(最好以类次报表的型式,不光是有图,还有其他数据)

Answer 10

weisai(与雪共舞) 
一个图中用两种方法表示，呵呵，为什么不用两个图呢，如上面代码中
建立两个pictureBox和两个Image就可以了啊，这样还可以把位置调整
成自己所要的位置wntpfi(宗)

Answer 11

关于weisai(与雪共舞)提到的问题你提到的需求，我觉得应该是一个封装的工作，打个比方
FORM的左上方是折线图，左下方是柱状图，右边是一个显
示数据用的DataGrid，这样就可以组合成你要的东东了~

Answer 12

我已经将其改成即支持.NET调用，也支持COM调用，即在ASP或VB等工具中也可以调用的了，ASP中调用程序如下
<%
Response.ContentType="image/png"
set test = server.createobject("psLibBase.ClsBuildChart")
Dim  objStream
    set objStream = test.MakeLineChart("红色,橙色,黄色,绿色,兰色,紫色,颜色一,颜色二,颜色三,testPie,color4,color5,color6,color7,color8,color9","100000,200000,150000,80000,110000,150000,250000,80000,80000,180000,100000,50000,150000,60000,170000,80000.5","测试",700,320,"单位(万)",true,"{0:N0}")
    Response.BinaryWrite  objStream.ToArray()
%>
