To be a little more clear, what I want to do is pull some data form the last line of some files, and then pass that data, come computations on that data, the number of files, etc to out-chart. So I have to construct an object of the type out-chart is expecting. This seems like it would be common enough to have some stock scripts for powershell that would do so.
I think I'll be able to figure it out by looking at thinks like the output of stuff like import-csv ./perf.csv |get-member but it would be much easier if someone had it done already and I could just stick in the part that generates the data I want!
