pareto chart

Dear all,

I have a table with a column reporting the total failures as a funcion of the working day.

I have three other columns reporting the specific failures occurred.

I need to mine this information: which is the contribution of the specific failures to the total failure during the months.

I was thinking to have a pareto chart reporting the failures frequency in which each histogram report the percentage of each specific failures.

Can you help me with that? can I obtain this kind of graph with sas? do you think this is the best way to obtain the information I need?

I'm not familiar with pareto chart, googled and found it's basically bar chart (histogram) overlay with a line plot. Tranditional SAS/Graph can do this with
a little trick. If you can provide a sample what you want and sample data, I can surely give it a try. New SAS SG family proc maybe easier, especially with GTL.

If you want to try by yourself, here is the hint with traditional SAS/graph:

Use gplot, with plot statement (left y axis) to draw the bar chart by using
needle type symple. Then plot2 (right y axis) to draw the line plot...

Good luck.
