Chartjs-Loading ViewBag data into a chart.js multichart

If it is an C# Array in the ViewBag:

var outcomeData = @Html.Raw(Json.Encode(@ViewBag.ChartOutput));

use Json.Encode and Html.Raw

Usefull Links:

• Check this for more information:
  MVC: Iterating a Viewbag array in javascript
• Or this for a 2D array if thats important for you: Pass 2D
  array from Controller Viewbag to JS

If it is a String in the Viewbag:
You can use the value from the ViewBag in JS like this:

var outcomeData = '@ViewBag.ChartOutput';

then you dont need the Html.Raw
