A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hello,
chances are the X Axis label source is not defined correctly.
Open the "Select Data" dialog for the chart and check the range selected in the Horizontal (Category ) Axis Labels setting. Make sure all desired columns are included.
Or select a data series in the chart and check the formula bar for the series formula
=SERIES(Sheet1!$A$4,Sheet1!$P$1:$S$1,Sheet1!$P$4:$AA$4,3)
The highlighted second parameter contains the range for the X axis labels. See how this one goes from column P to S, whereas the data goes from column P to column AA. Adjust the column S to read AA and the missing labels should appear.
