I have a chart that has year on the X axis and a COMBO Y axis, which should display 4 series of data (three lines on left Y axis and 1 bar graph on right Y axis). All are good except that one of the lines i snot visible. The data shows up as being part of the data series and the legend for the missing line is present, just not the actual line of data. I have tried to do: 'Select Data/ Hidden and Empty Cells/ Connect data points with line' but can't get the last data to show up. Anyone know how I can fix it? Thank you!
