This control creates a simple Pie Chart in a dialog

Sample Image - pie_chart_ctrl.gif


This control class CPieChartCtrl is derived from CWnd. The purpose is to create a simple 2D pie chart in a dialog. The code is created and compiled with Visual C++ 5.0 SP3 under Windows 98.

How to use

  1. Use the MS Visual C++ dialog editor to place a custom control on the dialog, and enter "PIE_CHART_CTRL" as the Class name.

  2. Add a CPieChartCtrl class member in the header file
    #include "PieChartCtrl.h"
    CPieChartCtrl m_wndChart;
  3. Subclass the class member with the control in InitDialog()
    m_wndChart.SubclassDlgItem(IDC_PIECHART1, this); //IDC_PIECHART1 is the control ID
  4. Use these functions to edit to chart
    // SetTitle(CString) - Set the chart title text
    m_wndChart.SetTitle("Chart Title");
    // Reset() - Reset the chart and delete all pieces
    // AddPiece(COLORREF colorBack, COLORREF colorText, 
    //            int nAngle, int strInfo = "");
    // Add one piece into the chart
    m_wndChart.AddPiece(colorBack, colorText, nAngle, strInfo);
