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.
But it depends on the cell size of the data and colum numbers. Hence forth the volume of data is restricting the rows in the excel, this is what we experienced. It is not mandatory to show 1048576 rows in one work sheet.
