CStatic-derived histogram control

Sample Image

Environment: VC5-6, Win9x, NT4-2000
Actually I wrote this code on VC6.0 and check them with BoundChecker 6.0.

The CAlexfStaticHistogram control is a lightweight class suitable for displaying histograms. You can add new columns, additional text, change text orientation and direction of motion (if you change data at runtime).

Using CAlexfStaticHistogram in a dialog is quite simple:
1. Include CAlexfStaticHistogram.h in your dialog class' header file.
2.Add member variables of type CAlexfStaticHistogram for every static text control you want to subclass.
3.Subclass the static text controls in your dialog's OnInitDialog() method and set the controls' style.


m_sHistogram.SetTextWidth(50); // Set text width (0 - no text)
m_sHistogram.SetTextLines(5);  // Set number of text lines (0 - none)
m_sHistogram.text[0] = "Z1";   // Set text (too easy to create special
m_sHistogram.text[1] = "Zz2";  // function for that)
// ...
m_sHistogram.SetMaxValue(99.9) // Set relatival maximum
m_sHistogram.Add(50);          // Add new column to histogram

If you want "dynamic" histogram - you can owerride, for example, OnTimer() and simply call:


m_sHistogram.Add(/*Value*/);

Please feel free to send me any suggestions about this control.

    Hi,

    It is a really cool control. I modified it a little bit to allow the user to select the bkcolor and the drawing color. There are minor changes, though. If you need them, I can email the new files to you.

    Best regards,

    Adrian.

    Hi! I hate pushing buttons, so I added this to your program. m_flag is defined in your header file and is intitially set "true" then the first time you press "add value" it starts the 1 second timer.

    void CAlexfHistogramDlg::OnButton1()
    {
    if (m_flag)
    {
    if (!SetTimer(1, 1000 /* Start timer*/, NULL)) // 1 second
    {
    MessageBox(_T("Not enough timers available for this window!"),
    _T("DLG:Histogram"), MB_ICONEXCLAMATION | MB_OK);
    }
    m_flag = false;
    }
    else
    {
    KillTimer(1);
    m_flag = true;
    }

    }

    void CAlexfHistogramDlg::OnTimer(UINT nIDEvent)
    {
    // TODO: Add your message handler code here and/or call default
    m_sHistogram.Add((DOUBLE) rand() / (DOUBLE) RAND_MAX * 100);

    CDialog::OnTimer(nIDEvent);
    }
