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.
This number of rows can be saved in the default format that version of Excel supports (e.g. XLSX). However, you will not necessarily be able to save in the older XLS format, which is still limited to 65,536 rows. Typing in a cell in row number 1048576 (e.g. A1048576) then saving to XLS format will cause a warning.
