TimeDataPlotter

Purpose

Plotting data over time

Why another plotting program?

There are a lot of powerful programs out there for plotting data, for example GnuPlot, Ploticus and many others.

TimeDataPlotter doesn't want to compete with these, but is designed to occupy a niche that the heavyweight programs don't really fit in: Quick and interactive displaying of data rows over a time scale.

Design goals of TimeDataPlotter

• display one or more data lines over a time scale
• Deliver nice results instantaneously, without the need for any kind of configuration
• Allow for interactive zooming into the data

License

GNU GPL v2

Limitations

• Doesn't scale well to large datasets. 10^4 points work nicely, 10^5 is really sluggish.
• Zooming is only supported on the time axis
• Currently only ISO 8601 time stamps are understood. While it's easy to add other formats, I rather convert my data to ISO than have legacy date formats around...

Neither of these limitations are inherent, so I happily accept patches that address them :-)
