I am putting together a Line - Column chart on 2 axes. The data series is very small: three business quarters, the column X axis is net dollars, the line X axis is net items. My problem is that the data points are showing for the line axis...but the line itself is not visible. When I format the the data series, the pattern pop-up clearly shows I've selected a navy blue, custom smoothed line with the data markers formatted to match.

I've tried every option in the formatting box and even rebuilt the chart but to no avail. Any insights or steps I may have missed?

Thanks,

NP
