Minor Tick Mark Labels in Charts

[jacksonstorms]

Hi and thanks for having me here,

I have a worksheet where the major unit is five and the minor unit is one. However, I can't seem to label the minor units. For example, 5, 10, 15, 20 etc is marked for the major units but 1, 2, 3 and 4 are not marked for the minor units. Is it possible to label the minor units with numbers like the major units? If so, how is this
done? Do these just have tick marks? I've attached a workbook to explain what I mean further. Thanks
