You can run the following macros to set the limits on the x-axis. This kind of x-axis is based on a count, i.e. just because the first column is labeled some number, it is still 1 on the axis scale. Ex. If you want to plot columns 5 through 36, set 5 as the x-axis minimum, and 36 as the x-axis maximum.
the following excel restrictions per worksheet apply: 1  excel 2003: can handle 65k rows. 2  excel 2007 (and later): can handle 1M rows.
The XLS format is the same format as earlier versions. When you use this format, you are restricted to 256 columns and 65,536 rows. When you save an Excel 2007 or Excel 2010 workbook in XLS format, Excel runs a compatibility check.
