geotargeting | uses HTML5 geolocation to display a map visualization | Data Visualization library

You should create a wrapper around your JSON structure in Java and pass it through to the controller as a @RequestBody. Here is what worked for me:

Your method is returning json (and the only thing in the response is "OK" - it does not contain any data that could be used to update your chart). There is no point setting ViewBag properties unless you return a view (and the view is using those values).

Your method should either

1. Return a partial view containing the html for a new graph based on the values of hourlyData and in the success callbacl of your $.post() function, update the DOM by replacing the existing graph, or
2. Return json containing the data for updating the graph, for example var data = hourlyData.Select(x => new { device = x.Hour.ToString(...), geekbench = x.Sales }); return Json(data); so that in the success callback, you can the update the data in the graph (e.g. using hourlyGraph.setData(data);)
