Empirical cumulative distribution function (ecdf)

[alternat]

Am I able to plot the empirical cumulative distribution function (ecdf) on Excel? And if so, how do I do it? Thanks.

Just to clear things up...

I'm no expert at this, but I think that ECDF just involves plotting the data using a line graph at discrete intervals instead of continuously as in CDF, and it looks like this - http://faculty.biu.ac.il/~htmldoc/matlab/toolbox/stats/ecdf.gif

Just to be sure, please check the Wikipedia entry at http://en.wikipedia.org/wiki/Empirical_distribution_function for this, although I think I understood it correctly.
