Description: Graph Legends are not displayed sometimes on newer version of Windows

Cause: Some of the fonts such as "Arial Narrow" are not installed with newer version of Windows.

WORKAROUND 1: 

Look if the recorded macro, sets the legend font to "Arial Narrow" or Arial Narrow Bold" .These fonts are not installed on the newer version of Windows. Change the font to use more standard "Arial"

WORKAROUND 2:

Set registry settings to explicitly map the “Arial Narrow” and “Arial Narrow Bold” to other fonts

For Example: 

Set registry : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes

"MS Shell Dlg"="Microsoft Sans Serif"

"Arial Narrow"="Arial"

"Arial Narrow Bold"="Arial Bold"
