Many distributions may have the same low order cumulants. GAMMADIST (which
is closely related to CHIDIST) is the most general skewed continuous
distribution natively provided in Excel.

http://en.wikipedia.org/wiki/Gamma_distribution
gives the mean, variance, skewness, and kurtosis in terms of the parameters
of the distribution. In particular, alpha=4 with beta=2.5 would have the
population mean=10 and population SD=5, but its population skewnss is 1.

I have some sales data that I am looking to chart based on it's
distribution. Using the NORMDIST function I was able to construct a
normal distribution chart for the mean and StDev of the data - however
how can I chart the data if it has a positive skew?

ie: Mean of 10, StDev of 5, and a Skewness of 1.28. I would like to
create a distribution curve based on those parameters.

Thank you!
