When I do a Print Preview, my graphs are complete with all data labels, axis titles, chart titles, gridlines, etc. When I print to my printer or to a .pdf (e.g., using Adobe PDF), I only get my gridlines, my 7 graphed lines usually with all of my x-axis labels and sometimes a few of my data labels (basically just my 7 graphed lines with nothing else). I do not get my data labels, y-axis titles, chart titles, etc.
I do monthly reports like this, and this problem just started a couple of months ago.
I have attached an example.
I am using MS Office Excel 2007 on a Windows 7 64-bit machine with 8GB of RAM.
