    What is MathGrapher
    MathGrapher is a Mathematical Graphics Tool. It ranks between graphical calculators and full-fledged mathematical tools like Mathematica.
    MathGrapher is powerfull and easy to use.
    Especially Students, Scientists and Engineers can benefit form this product.

    Is MathGrapher different from other graphical calculators
    MathGrapher will give you more than other mathematical graphing tools for a relatively low price (see Introduction in the main menu bar of this website)

    Why should I complete the questionnaire
    Mathgrapher is a new software product and, although we did our best to make it bug-free and user-friendly, we realize that improvements are possible. Therefore we would be very gratefull receiving your comments, wishes, or anything that might help to improve Mathgrapher.

    The downloaded file is too small
    It might occur that when you're trying to download one of our programs, the download will be 'completed' although only about 100k is actually downloaded. This is due to serverproblems. The installation file is 4.86MB. If the downloaded file is much smaller, just download again. The second time the download will be completed without any problems.
    If there are any other download / installation or runtime problem, please report this to support@mathgrapher.com

    Windows XP problems
    Some users experience problems when running Mathgrapher under Windows XP. Mathgrapher has a 3D Viewer window which uses OpenGl (a standard being used by many 3D programs, games and DVD players). If your video adapter does not support the OpenGl standard you may experience some or all of the following symptoms: (see also Microsoft Knowlegde Base
    1. An error at the start of the program saying: "Gino OpenGl driver error. 24 bit RGBA pixel format not available. In this case the image in the 3D Viewer may not be visible or distorted.
    2. No error message at the start, but the image in the 3D Viewer may not be visible or distorted.
    3. When you start Mathgrapher the screen blackens and your PC reboots giving you the message that a "serious error has been encountered".

    In order to check Mathgrapher's 3D Viewer do the following:
    1. Press Data in the main menu bar
    2. choose Select Tab below the data grid and push Select all
    3. Press the Prepare Graph button in the main menu bar. The 3D Graph window and the Properties window are opened.
    4. In the properties window menu bar press: 1) 3D, 2) 3D Viewer, and 3) Draw in 3D Viewer.
    A red shaded surface graph representing the data should the appear. If not continue reading.

    Solutions to Windows XP problems
    To resolve these problems you probably have to update your video adapter driver (instructions follow). Before you do that you must try to disable the hardware acceleration to see if avoiding hardware alleviates the problem.
    1. Disable hardware acceleration: Right-click on the Windows desktop and select "Properties". In the ensuing dialog box, select the "Settings" tab and click "Advanced". On this page, select the "Troubleshooting" or "Performance" tab, and slide the "Hardware acceleration" slider all the way to the left. Now click "OK" on each of the dialog boxes.
    2. Update your video adapter driver. One way to do it is to go to the windows update page and wait until the "SCAN FOR UPDATES" button appears on the screen and click it. When the scan is over click Driver Updates from the menu on the left and install the drivers that appear.
      It is not difficult to install (or update) a new driver yourself.
      • First thing is to check what kind of video card and graphics driver you are using
        1. Open the Display Properties dialog by either of the following ways:
        2. Right-click on any blank spot of your Desktop and select Properties.
        3. Click on the Start button > Settings > Control Panel > Display icon.
        4. Click on the Settings tab, and the click on the "Display Type" button. In Windows 2000 and XP, click on the "Advanced" button and then select the "Adapter" tab.
        5. Driver Information is in the middle of the Display Type dialog box. In Windows 2000 and XP, detaileinformation can be found by clicking on the "Properties" button.
        Note that the version number on the Display Type dialog box is a little bit different than the actual version number from the driver vendor's ReadMe file.

      • Next go to your video card provider and download the latest video adapter driver (Note that in some cases older versions are better than the newest ones).
        Here are some useful links:

      • It may be necessary to do an update rather than installing a new driver. Plug & Play operating systems have a habit of trying to install a previous driver when they restart. It can defeat your desire to install a new driver. To install a new driver, complete the following steps:
        1. Right-click on the display background and select properties to open the Display dialog (or go to Start / Settings / Control Panel / Display)
        2. Click the Settings tab.
        3. Click the Advanced button
        4. Click the Adapter Tab.
        5. Click the Properties button.
        6. Click the Driver Tab.
        7. Click the Update Driver button.
        8. In the Upgrade Device Driver wizard, click the Next button.
        9. Select the Display a list of known drivers…option. Click Next.
        10. Click on Have Disk… Use the Browse button to navigate to where the driver is unpacked and ready for installation.
        11. Select the file with the .inf extension.
        Hopefully your new driver installed smoothly. Check this by repeating the steps described above (Check Mathgrapher's 3D Viewer). Don't forget to disable hardware acceleration!!)
