One note about graphs.
All the software I have seen uses log files that easily import or directly transfer into spreadsheets, perhaps Excel being the most common.
If you want good graphs however you have to do them yourself. The software cannot possibly know what kind of resolution you need in the graphs, and plotting up 50 gazillion data points so that the graph is useable requires massaging the data with your own spreadsheets.
My solution is to have an Excel template, paste the data into the template, have the template break the data down into 15 or more graphs that allow me to examine the data minute by minute, which is necessary for me to make accurate diagnosis of problems, which is our main use of the data aquisition system.
