Implementing RGraph in iOS applications

I am trying to implement RGraphs into my iphone application. However, I am unable to get how to include the files and how to run the javascript on my UIWebview so that it would display the graph.

It would be great if someone could help me out.

 

thanks for the reply.. I did look into Coreplot but it was a bit too complicated for me.. so I was looking into some alternatives..

 

Calling Javascript using UIWebView

I am trying to call a javascript in a html page using the function -

Code:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writablePath = [documentsDirectory stringByAppendingPathComponent:@"BasicGraph.html"];
NSURL *urlStr = [NSURL fileURLWithPath:writablePath];

NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *myPathInfo = [[NSBundle mainBundle] pathForResource:@"BasicGraph" ofType:@"html"];
[fileManager copyItemAtPath:myPathInfo toPath:writablePath error:NULL];

[graphView loadRequest:[NSURLRequest requestWithURL:urlStr]];
[graphView stringByEvaluatingJavaScriptFromString:@"methodName()"];

Here is the javascript on the html page -

Code:

<script>
function methodName()
    {
        alert(hi);
    } 
window.onload = function ()
    {
      // Code Omitted
    }
</script>

However, the function methodName() is not getting called but after window.onload = function () everything is working fine..

I am trying to integrate RGraphs into my application and Basic.html is the html page in which the javascripts are written.

It would be great if someone could help me out with this.

 

Thank you.. I figured out that just before I saw your reply.. and I forgot to set the webview delegate to self.. now it is working..
thanks...
