Charting data sent via serial port in real time
Often it is needed to chart in real time the values coming from the serial port (RS-232). In Arduino environment it is a common need. If you have some values, only one possibility is offered by the Arduino IDE: to use the serial monitor. But on the serial monitor, the values are textual and also they are difficult to read during the elaborations.
I found a simple tool made with QT graphic libraries, that needs only a light parametrization for plotting in an easy way the serial values. The sw is SERIALCHART. Some details and explenation here: http://robottini.altervista.org/charting-data-sent-via-serial-port-in-real-time/
