I am trying to bind data to graph through razor. I pull data through a jquery ajax call and planning to bind the resultant data to graph. Is there any option to include razor code inside jquery success function? How can I bind count values to x,yValues in chart code?
https://www.asp.net/web-pages/overview/data/7-displaying-data-in-a-chart
@{
var CountsPath = Server.MapPath("~/Content/Images/counts.jpg");
if (File.Exists(CountsPath))
{
File.Delete(CountsPath);
}
var PathName = "~/Content/Images/counts.jpg";
if (!File.Exists(Server.MapPath(PathName)))
{
var chartImage = new Chart(600, 400);
chartImage.AddTitle("Count");
chartImage.AddSeries(
chartType: "Pie",
name: "Sales",
axisLabel: "Count",
xValue: new[] { "2011", "2014" },//need from json
yValues: new[] { "40", "285" });//need from json
chartImage.Save(path: PathName);
}
}
Jquery script
<script>
$(document).ready(function () {
$.ajax({
type: 'get',
url: '/Home/GetSales',
success: function (data) {
//Bind sales data counts by year result to graph
},
error: function (response) {
alert(response.Message);
},
dataType: 'json'
});
});
</script>
Result Json:
{"Sales":[
{"Year":"2011", "loc":"ca"},
{"Year":"2014", "loc":"wa"},
{"Year":"2011", "loc":"wi"}
]}
Edit: Or Can I use jquery result groupd by inside Razor code?
As @Stephen Muecke said, this kind of solution is not possible, but, perhaps, you can try it by using a partial view to render your graph in the server and then, inject it with ajax in your web page.
Something like this:
<div>
your page content
<div id="graph">
</div>
</div>
script:
$("#graph").load("MyAction", { yourdata }, function() { yourcallback });
And in "MyAction":
public ActionResult MyAction( ... ) {
...
return PartialView(Model);
};
So, in this case, in 'MyAction' partial view, you can generate your graph.
