I apologize in advance for being such a noob.

I was interested in using Zoho Sheet to make some simple line charts for two columns of data.  I wanted the first column of data to represent the values of the  x axis, while the second column is the actual data set.  Every line chart I make, the x axis just ascends from zero upward in increments of .5 units.  I've looked through the menus in hopes of finding a way to define the x axis, but I can't find one.  I'm sure I've missed something.

Any help with this matter would be greatly appreciated.

Sincerely,

Dave Jones
