PEMBUATAN GRAFIK MENGGUNAKAN Ms. Visual Basic

Halo teman Dunia IT!,

Apa kabar? disini admin akan membagikan tutorial nih cara membuat grafik dengan aplikasi Ms. Visual Studio, langsung aja langkah langkahnya :

1. Pastikan laptop telah terinstall Microsoft Visual Studio (Versi Bebas).

2. Buka aplikasi Microsoft Visual Studio.

3. Kemudian pilih new file - visual c++ - MFC Application.

4. Cari di sebelah kanan Solution explorer cari source file kemudian klik kiri,lalu klik Add - New item - C++ File (.cpp).

5. Masukkan Codingan yang telah anda buat sebelumnya, atau :

// nyobaView.cpp : implementation of the CnyobaView class

//

#include "stdafx.h"

// SHARED_HANDLERS can be defined in an ATL project implementing preview, thumbnail

// and search filter handlers and allows sharing of document code with that project.

#ifndef SHARED_HANDLERS

#include "nyoba.h"

#endif

#include "nyobaDoc.h"

#include "nyobaView.h"

#include "math.h"

#ifdef _DEBUG

#define new DEBUG_NEW

#endif

// CnyobaView

IMPLEMENT_DYNCREATE(CnyobaView, CView)

BEGIN_MESSAGE_MAP(CnyobaView, CView)

       // Standard printing commands

       ON_COMMAND(ID_FILE_PRINT, &CView::OnFilePrint)

       ON_COMMAND(ID_FILE_PRINT_DIRECT, &CView::OnFilePrint)

       ON_COMMAND(ID_FILE_PRINT_PREVIEW, &CnyobaView::OnFilePrintPreview)

       ON_WM_CONTEXTMENU()

       ON_WM_RBUTTONUP()

END_MESSAGE_MAP()

// CnyobaView construction/destruction

CnyobaView::CnyobaView()

{

       // TODO: add construction code here

}

CnyobaView::~CnyobaView()

{

}

BOOL CnyobaView::PreCreateWindow(CREATESTRUCT& cs)

{

       // TODO: Modify the Window class or styles here by modifying

       //  the CREATESTRUCT cs

       return CView::PreCreateWindow(cs);

}

// CnyobaView drawing

void CnyobaView::OnDraw(CDC* pDC)

{

       CnyobaDoc* pDoc = GetDocument();

       ASSERT_VALID(pDoc);

       if (!pDoc)

              return;

       int data[] = {15,10,30,40,10,30,20,20,40,60};

       int sisi = 200;

       int titikawal = 200;

       int a = 5 ;

       int b = 5 ;

       int i = 0 ;

       int grid = 10;

       int lgrid = 2;

       int titikakhir[] = {titikawal+sisi,titikawal+sisi};

       pDC->MoveTo(titikawal,titikawal);

       pDC->LineTo(titikawal,titikawal+sisi);

       pDC->LineTo(titikawal+sisi,titikawal+sisi);

      

       pDC->MoveTo(titikawal-a,titikawal+b);

       pDC->LineTo(titikawal,titikawal);

       pDC->LineTo(titikawal+a,titikawal+b);

       pDC->MoveTo(titikakhir[0]-b,titikakhir[1]+a);

       pDC->LineTo(titikakhir[0],titikakhir[1]);

       pDC->LineTo(titikakhir[0]-b,titikakhir[1]-a);

       for (i = 1 ;i < grid;i++ )

       {

              pDC->MoveTo(titikawal + (sisi/grid)*i,titikawal+sisi+lgrid);

              pDC->LineTo(titikawal + (sisi/grid)*i,titikawal+sisi-lgrid);

              pDC->MoveTo(titikawal + lgrid,titikawal+sisi-(sisi/grid)*i);

              pDC->LineTo(titikawal - lgrid,titikawal+sisi-(sisi/grid)*i);

       }

       for(i = 0 ; i < grid ; i++){

              if (i == 0){

                      pDC->MoveTo(titikawal + (sisi/grid)*i,titikawal+sisi-data[i]);

              }

              else{

                      pDC->LineTo(titikawal + (sisi/grid)*i,titikawal+sisi-data[i]);

              }

       }

}

// CnyobaView printing

void CnyobaView::OnFilePrintPreview()

{

#ifndef SHARED_HANDLERS

       AFXPrintPreview(this);

#endif

}

BOOL CnyobaView::OnPreparePrinting(CPrintInfo* pInfo)

{

       // default preparation

       return DoPreparePrinting(pInfo);

}

void CnyobaView::OnBeginPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)

{

       // TODO: add extra initialization before printing

}

void CnyobaView::OnEndPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)

{

       // TODO: add cleanup after printing

}

void CnyobaView::OnRButtonUp(UINT /* nFlags */, CPoint point)

{

       ClientToScreen(&point);

       OnContextMenu(this, point);

}

void CnyobaView::OnContextMenu(CWnd* /* pWnd */, CPoint point)

{

#ifndef SHARED_HANDLERS

       theApp.GetContextMenuManager()->ShowPopupMenu(IDR_POPUP_EDIT, point.x, point.y, this, TRUE);

#endif

}

// CnyobaView diagnostics

#ifdef _DEBUG

void CnyobaView::AssertValid() const

{

       CView::AssertValid();

}

void CnyobaView::Dump(CDumpContext& dc) const

{

       CView::Dump(dc);

}

CnyobaDoc* CnyobaView::GetDocument() const // non-debug version is inline

{

       ASSERT(m_pDocument->IsKindOf(RUNTIME_CLASS(CnyobaDoc)));

       return (CnyobaDoc*)m_pDocument;

}

#endif //_DEBUG

// CnyobaView message handlers

6. Klik F5 untuk start program, hasilnya seperti di bawah ini :
