I prefer this over having to install python like some of the other graphing programs do. It's written in java so you'll need the JRE.

Also, showing multiple graphs requires manual scaling, but in spite of all this, it's still very useful. Live Graph is slightly buggy when caching data and I haven't found a way to set a moving window to display results. Live Graph is a better option and I use it in conjunction with Tera Term which gets the data via the USB/serial link (and saves it to a log file which then Live Graph polls).

Using this library, the time to setup a communication between Arduino and PC went from usually half a day to 5 minutes. plot complex data (not just a time varying value)Īll of the above without using proprietary solutions or bloated GUIs.write quickly PC scripts to control an Arduino.I developed it because I could not find a solution that would allow me to: Then you can connect, ls(list) received topics, print data received on a topic, pub(publish) on a topic, or open a plot on a topic to display received data in real-time Once installed with pip, the command line can be started with pytlm I believe those features are simply unique for such a project. Once, again the plots will figure everything out, plot your data in 2D or 3D space and you can focus on developping your app. In a near future, it is planned to add support for spatial coordinates (xyz data), that will allow you to plot immediately spatial data. The plots opened from the command line interface understand the type of data, and for arrays, rather than plotting each sample versus time, sample will be plotted against its own index.

For now arrays and sparse arrays can be send from the embedded board. The protocol supports complexes data structures. It is able to open high-performance plots (much higher that what can be done with matplotlib) just by typing a command. The power of this library comes from the desktop command line interface (that requires no programming skills in python). If you don't want to read this long post, see A walkthrough of all the awesome features in it It is a communication protocol, highly simple to use, with a clean interface, that enables bidirectionnal communication with Arduino/Mbed devices.

# Note reverse video here ^^^ til I find a way to put it in the script Something I found very useful was to script it to reload my terminal program's logfile periodically so i got a dynamic graph as my experiment progressed.Įdit: Here is the GnuPlot script that plots it: #!/usr/local/bin/gnuplot -rv

Advantages: It's very flexible, scriptable, and freely available.ĭisadvantages: A bit complex to learn (but I figured out how to get started in a few minutes, and quite functional in an hour or two), runs in a terminal window (if you consider that a disadvantage).
