Handling the csv file generated by Application data logging

[BRIan]

Excel is OK but it takes a while to set up a download into a graph and is awkward to manipulate, especially when there is a heap of data points. Has anybody come across a quick method to manipulate the data and enable zooming, truncating etc to home in on a particalar time slice?

You could do a lot with visual basic, C++ or some other code language.
Question is, who is the intended user, your self or a customer?

I'm sure there are data manipulation programs out there, doing all sort of different tasks.

I have used Gnuplot http://www.gnuplot.info/ for this, because it is a lot faster than working with a spreadsheet. For plotting various log files. But it takes some time to learn, and make a script that works good for your data and application.

I'm also happy to know if someone know of a simple program to plot graphs from custom log data files.
