General TCPIP/Serial Live Plot Utility for MATLAB

This utility is published on MATLAB Central File Exchange Link

Live plot utility plots ASCII coded streaming data over TCP/IP or serial connection.  Demo files are attached for ease of use. Current code should cover a variety of situation. Modify the code to suit your special need. 

Data format: 

Each line of the streaming data is considered as a sample. The first 

column is considered as a label of data. It have to match with a 

preset keyword to be considered as a valid sample. The following 

columns are numbered 2, 3, 4 .... Data can be extracted from these 

columns. For example,

      TestPlot 0.001 2.641 231 0

is a sample with keyword TestPlot. The following columns contains 4 

numbers that available for plotting.

Usage:

To plot data, issue a command

    live_plot(data, conn);

to open up the plot window, where data contains description of data 

stream and datasrc contains information about the underlying connection 

of data.

  data.keyword contains keyword of data to be plotted data.columns 

                  is a vector contain all the columns need to be plot 

  data.Ts sample time of data, this is used to 

                  recover the real time vector of plot. It is assumed 

                  data comes at a constant frequecy. 

  data.Twindow set the width of plot window in same unit as Ts. 

  data.YRange Y direction range. Set to -1 for adaptive.

  conn.type Type of connection 'tcpip' or 'serial' 

  conn.host Remote host name of data, valid for 'tcpip' only. 

  conn.port Remote tcpip port, or COM port number, in integer. 

  conn.baud Baudrate of communication, in integer, valid for 

                  'serial' only.
