Here's the big picture. I need to Design an Excel spreadsheet that will import a csv text file that is 575 colums wide (fields) and 720 rows (records) that I can then graph.
Now the details. The purpose is to be able to graph historical data from a Data Logger that collects data every two minutes (720 rows a day) for 575 different pieces of equipment, and I will only need to graph a couple things at a time. I started doing this through Access and imported the file into a 2-D Array in VBA since there is the 256 column (field) limit, then just pulled the data I needed out of the array and put it into a table which I could use to chart. But all the access guys say that Excel is much better at charting and more flexible so I decided to see what was possible on this side. I was thinking of approaching it simlarly in Excel but instead of a temp charting table I would use a Sheet. I really am doing no calculations and the only user input will be to select what pieces of equipment they want to graph and the time frame for which to graph. I currently don't have plans for the ability to do more than one day as that would be more than one file import but it would be a nice feature.
I guess what I'm looking for is a little direction from those of you who are more seasoned in this to hopefully make this development a little less painful. Thanks!
