how to get database value by button into chart.

[mwy_liao]

I want click a button, and go to database select value and bring to create chart.
I used ajax to query data but can’t bring json into CanvasJS.

My sample code.

I pass query database, use DataService GetRandomDataForCategoryAxis replace.
Home/Index.cshtml have a CreateChart button.

@mwy_liao,

The response that you are passing to view seems to be string & not JSON. Passing JSON seems to be working fine. Please download updated sample from here.
