How do i implement high-chart in asp.net (c#) ?

Hello everyone 
I have some problems in programming the following algorithm in ASP.NET which I’ll be so thankful anyone can help. 
I have a store procedure by the name of Sp_SumProblem  that takes@ S_date (Start Date), @F_date(Final Date) and a @personnel Code, as input variables and should print out type of foods and some bad factors of that particular food (For example Calorie, Fat, Salt etc.) as a number.
Example:
Food type          Problem                           Count
1                  Calorie                             5
2                  Salt                                6
3                  Calorie and Salt                    11
. 

In C#, I have two Text boxes that take a start and finish time and I should extract data from that store procedure at the meantime.

What I have tried:

I have programmed this store procedure by EDMX. Now, I am wondering how I can write down this values in C# and illustrate the percentage values in a Pie Chart (high charts). By percentage value, I mean the fraction of counts to total reserved food for every individual (extracted from another store procedure so-called Sp_Reservedfoodcount)
