Multiple Y Axes for Excel (Multy_Y)


Multy_Y creates 2 or more Y axes in Excel.

Multiple Y axes plots are created from existing Excel Charts. Each Excel chart appears as a new Y axis on the Multy_Y plot. The plot is a picture that appears on a separate Excel Chart.


Note: To create interactive Multiple Y axes plots, EZplot must be purchased instead. Interactive plots allow you to click on the plots and change titles, scales, labels, etc...  There are videos about Multy_Y on the EZplot page.

    The error occurs because "Visual Basic for Application" was not installed during the software installation. Close Excel. In the Windows Control Panel choose Add or Remove Programs (or Programs and Features in Windows Vista or Windows 7). Select Microsoft Office then Click Change. Select Add or Remove Features then in the Office Shared Features list select Visual Basic for Applications -> Run from My Computer and then Continue. You can then run the software when you reopen Excel.
