I am having problems displaying mulit-level x-axis labels. Even though I
have selected and increment of 1, the higher levels only print periodically.
For example, I have three years with monthly data by hours. The data are all
there but only one year label appears, one in five months, and all of the
hours labels. Is there a specific format in the spreadsheet that will allow
all levels to be printed to the graph? I have them each in separate columns
right now.
