I have a workbook with three sheets: data and two charts. I've been using the
first chart for some years and decided to add a second slightly different chart.
My problem is that on my first chart sheet, the chart is fine, but the
background is solid grey, i.e., no gridlines visible. When I created the second
chart, again the chart is fine but I can't seem to find out how to make the
background grey like the first chart. Maybe I stumbled on to it by "blind luck",
but all I see is the chart on a "bed" of empty grid lines. Help, please!
