Comments on: History, statistics, data, and a call for graphing help http://cow.org/c/archives/24 Community supported Caltrain notices, one tweet at a time Wed, 15 Sep 2010 01:02:47 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: George http://cow.org/c/archives/24/comment-page-1#comment-27 George Thu, 30 Oct 2008 18:01:23 +0000 http://cow.org/c/?p=24#comment-27 I'm running a similar data gathering effort but so far have only worried about getting columar data out. With regards to the graphing, do you want to produce on demand web refreshable charts, or static files? My workflow would likely start with excel to model what data and what kind of graph / chart to go with. Colleagues at work are quite happy with an open source C# / .NET library called zedgraph.

Very intuitive, and lots of options for displaying multi-axis or multi-series data. Highly recommend xgobi over gnuplot.

It makes probably the best plots with the least adjustment. Xmgrace is an alternate, but you need to do a lot of manual tweaking, and it's autoscale is poor. I could help you with xmgrace, but with gnuplot, I'm also a beginner. I say bite the bullet and go with gnuplot. It makes probably the best plots with the least adjustment.

Sorry I can't help with the specifics. Does my backwards "329 NB ..." (train number then direction) screw up your pattern matching? Should I switch it around to the preferred format as outlined in your Updating guide? You’re a genius with this graphing idea. Sorry I can’t help with the specifics.
