如何传递图表的值，在以下网址中。

How to pass the value for chart, in this below url.

NSString * myurl = @http://chart.apis.google.com/chart?chf=bg,s,67676700&chs=300x225&cht=p&chd=s ：Uf9a& chdl = 30°| 40°| 50°| 60°;
NSString * theurl = [myurl stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding];

下面是我的相应代码：

NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:theurl] cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                    timeoutInterval:60.0];                                              

NSURLResponse* response;
NSError* error;
NSData *imageData=[NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error];
NSLog(@"%@",error); 
NSLog(@"%@",response);
NSLog(@"%@",imageData); 

UIImage *myimage = [[UIImage alloc] initWithData:imageData];

graphimage.image=myimage;

推荐答案

嘿，你必须把自己的输入本身，但你需要知道参数和它为什么使用。请检查此API文档以了解该参数
http：// code.google.com/apis/chart/image/docs/making_charts.html

Hey you have to put your own input in the url itself but you need to know the parameters and what for it is used. check this API doc to know about that parameters http://code.google.com/apis/chart/image/docs/making_charts.html

http://chart.apis.google.com/chart ？chf = bg，s，67676700& chs = 300x225& cht = p& chd = s：Uf9a& chdl = 30 °| 40°| 50°| 60°

http://chart.apis.google.com/chart?chf=bg,s,67676700&chs=300x225&cht=p&chd=s:Uf9a&chdl=30°|40°|50°|60°

在此网址中，您可以更改chf chs值。

In this url change the chf chs value whichever you want.
