An easy way to plot in a Visual Studio 2019 C++ program.

Question

I want to use Visual Studio 2019 C++ on my Windows 10 machine for simulation of a complex system (An alternative is OCTAVE, but that is not so fast). I need to plot data as the execution progresses.
I have searched the internet for ways to do the plotting and gnuplot is a possibility, but it is very complex to install and make work, and the descriptions, which I have found of how to install and use it, are incomplete.

Is there a step by step description for idiots/novices of how to install and use gnuplot in Visual Studio 2019 C++ ?

Is there a free plotting library offering 2D and 3D plotting in Visual Studio 2019 C++ and a step by step description of how to install and use?

I am aware that I may transfer data from the application to a plotting application, but that does not meet my needs.

Sorry, but I really need a complete and detailed description of the installation and use.

Another simple way is to use System.Windows.Forms.DataVisualization.Charting
with C++/ CLR (Create C++ Windows Forms application in Visual Studio 2017)

A test (Chart added from Designer) :

        this->chart1->Series->Clear();  
		this->chart1->Titles->Clear();  
		Title^ title1 = (gcnew Title());  
		title1->Text = L"Title Test";  
		this->chart1->Titles->Add(title1);  
  
		Series^ series1 = (gcnew Series());  
		series1->Name = L"Series Test";  
		this->chart1->Series->Add(series1);	  
  
		//series1->XValueType = ChartValueType::Auto;  
		this->chart1->ChartAreas[0]->AxisX->Interval = 1;		  
		series1->ChartType = SeriesChartType::FastLine;  
		  
		series1->Points->AddXY("January", 100);  
		series1->Points->AddXY("February", 200);  
		series1->Points->AddXY("March", 300);  
		series1->Points->AddXY("April", 500);  
		series1->Points->AddXY("May", 400);  
		series1->Points->AddXY("June", 800);  
		series1->Points->AddXY("July", 1000);  
		series1->Points->AddXY("August", 700);  
		series1->Points->AddXY("September", 500);  
		series1->Points->AddXY("October", 300);  
		series1->Points->AddXY("November", 600);  
		series1->Points->AddXY("December", 700);

Here's a YT video "A detailed walkthrough of setting up Visual Studio C++ to call Gnuplot on a Windows machine."

Also, there's Python based plot library.,People who are familiar with matplotlib tool in Python, there is a very elegant interface available to call matplotlib of python from C++. A simple example may look like this (source) and the matlabplotcpp.h is available here.

 #include "matplotlibcpp.h"
 namespace plt = matplotlibcpp;
 int main() {
     plt::plot({1,3,2,4});
     plt::show();
 }

I must get in touch with the developer in order to create a service-providing structural engineer website. Please get in touch with me if you can do this.
