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 exact number of rows and columns are 1,048,576 rows and 16,384 columns. You've never going to need this many!) You can click a number to highlight an entire Row. If you look at the image below, you'll see that Row 5 has been highlighted. The image above is from Excel 2007.
