How do I use "surf" function in C++ with matlab coder?

Hello, I'm trying to use matlab coder to convert a "surf" function. I generated the .lib files and it can be compiled in Visual Studio, but it won't show any figure during debug, how can I achieve this? Thanks! Following is my code.

matlab code:

if true
function threed_surf (x,y,z)
[XX,YY]=meshgrid(x,y);
surf(XX,YY,z);
end
end

C++ test code:

if true
#include "threed_surf.h"
#include <iostream>
using namespace std;
int main()
{
  double x[20] = { 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 };
  double y[20] = { 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 };
  double z[400]= { 0 };
  threed_surf(x, y, z);
  system("pause");
  return 0;
}
end

P.S "if true... end" not in my code, but for the format of the bbs

Take a look at all functions supported for C/C++ code generation (surf is not one of them): https://www.mathworks.com/help/coder/ug/functions-supported-for-code-generation-categorical-list.html
