Hello, I am a novice Excel user so please excuse my ignorance of most excel features.
I have been given the task of charting a row of numbers over a 48 month period. I marked the row of data I want on the spreadsheet and created a line chart. The Y axis looks fine. It has the values that I need. The problem is the X axis. By default it has numbers 1 to 48. I need the values on the X axis to be the month and year (Feb-05) contiguously to Dec-08. I have tried many things and when I am able to get the month and year to appear properly on the X axis, the chart data disappears. I have tried modifying values for both the x and y axes, but I can not get the line data back on the graph. I am sure I must be overlooking something very basic.

I appreciate any assistance you can provide!
