Real time serial data plot

The real time serial data plot program available from this page plots Comma Separated Data Values (CSV) coming in over the serial port. Each record consists of single line terminated by a new line.

The program has the following features:

• Light and fast native program. The entire zip file is under 100KB
• Simple configuration
• Simple to use. Just unzip, edit the ini file and run. No installation necessary.
• Ability to save plots as image files
• Independently specify maximum and minimum of different data columns
• Ability to log all data received
• Parses hex data 0x13AB, floating point data and integer data
• Free

We will be updating the program as time goes on. Please check back for updates. If you wish the program to have additional features please request it using the form below.

Why another real time serial data plot program?

We needed to plot data coming in over the serial port from a product that we had developed. We figured this is an easy task and there should be loads of software available on the web to do this.

We spent a fruitless couple of hours searching for a simple, light program that would do it do out of the box. There are plenty of plotting programs there but none would do exactly that. Most of them required installations of weighty libraries. One of them nearly worked but then crashed when we ran it.

We finally gave in and coded this program.

Possible Features

While coding the program we thought of additional features, for example

• Ability to parse arbitrary framed binary data, for example packetized data with with a packet header and packet length and raw data as unsigned or signed, 8,16,32,64 bits, big endian or little endian
• Ability to read real time data from log files
• Support for additional platforms - Mac, Linux, BSD, Android
• Configuration GUI

These are not currently implemented as we did not need them in our application. We will implement these and other features, time permitting, if we receive enough feature requests.
