I'm using Google chart api to show the graphs. It was working first time but now if i'm working on graphs then it is not showing the graphs. {
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[webView setDelegate:self];
NSString *strHtml = [[NSString alloc] initWithString:
开发者_StackOverflow社区 @"<html>"
@"<head>"
@"<script type=\"text/javascript\" src=\"https://www.google.com/jsapi\"></script>"
@"<script type=\"text/javascript\">"
@"google.load(\"visualization\", \"1\", {packages:[\"corechart\"]});"
@"google.setOnLoadCallback(drawChart);"
@"function drawChart() {"
@"var data = new google.visualization.DataTable();"
@"data.addColumn('string', 'DAY');"
@"data.addColumn('number', 'RATE');"
@"data.addRows(1);"
@"data.setValue(0, 0, 'M');"
@"data.setValue(0, 1, 20);"
@"var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));"
@"chart.draw(data, {width:320, height:300, title: 'Daily Winning Statistics',"
@"hAxis: {title: 'Year', titleTextStyle: {color: 'red'}},"
@"vAxis:{minValue:0,maxValue:100},"
@"colors:['red']"
@"});"
@"}"
@"</script>"
@"</head>"
@"<body>"
@"<div id=\"chart_div\"></div>"
@"</body>"
@"</html>"];
NSLog(@"string : %@",strHtml);
NSLog(@"Loading start..");
[webView loadHTMLString:strHtml baseURL:nil];
//[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://google.com/"]]];
NSLog(@"Loading finish");
[self.view addSubview:webView];
}
Is there any problem with baseURL ? or any other. Actually when i started code ,it was showing me graphs but now it's not showing. I don't know what's the wrong with this ?
And You can also copy HTML in API Playground where you can show the chart is showing there but not shown in webview.
URL : http://code.google.com/apis/ajax/playground/?type=visualization
I have just used HTML nothing more !
you can copy HTML code from this link : Copy HTML code
Plz help me
Thanks
I think the problem is that you defined only 2 columns
@"data.addColumn('string', 'DAY');"
@"data.addColumn('number', 'RATE');"
and you 're trying to add 3 values for each row
data.setValue(0, 0, 'M');"
"data.setValue(0, 1, 20);"
and you're not respecting the data types that you defined for each column.
