Folks, could anyone recommend a decent free graphing package? Open source would be nice. Primarily I want to read data from the serial port and graph it so one that could do that, based on config of some sort for data format, would be great.
Faling that, a package that could take a feed of any sort and produce nice graphs would do. I'm a software engineer by trade so no issue in writing something to pull/push data from the serial port to the software but I don't want to re-invent the wheel in terms of GUI and producing the graphs.
I've been using a "processing" GUI I found on the arduino forum, which is fine, but a bit limited and clunky, though it does provide the ability to send data on the serial port too which is handy.
