I have just finished dealing with a virus issue (I think) on my computer and Excel was left not displaying charts. Not certain that the virus issue was related to the Excel issue but the bottom line is that for some reason, Excel will not display charts. The data is still there and I can select data and attempt to "insert" a chart but the chart will not work and display. I have loaded older files and the charts do not display on those files either.

Any idea?
