For a discrete probability mass function, you can plot the cumulative
distribution using an XY (Scatter) chart with error bars. For instructions,
see Tushar Mehta's web site

For a continuous probability density function, you can plot the cumulative
distribution using an XY (Scatter) chart using many pairs of x and f(x) in
worksheet cells (and optionally using the "smoothed line" format).

What is the simplest way to plot a commulitive distribution function
graph? I
would like to add several graphs in one chart if possible.
