Excel_Format_Axis

Hello there.

I am trying to format an axis for a line graph that I am making in excel. When I click on the Format Axis and go to the axis options, it will not allow me to change the axis options. Right now the options that I have are to "Automatically select based on data", "Text axis", and "Date axis". With the other graphs that I have in this same file I am able to format the axis by a bound range. Wondering how I can switch from "Automatically select based on data" to creating my own range bound or just manually selecting from the data I am trying to use. Wish I could insert images here but it says that I am not allowed to do so. Let me know what y'all think. Cheers.
