This example creates the serial port object s, connects s to the device, writes and reads text data, disconnects s from the device, removes s from memory using delete, and then removes s from the workspace using clear. If you use the help command to display help for delete, then you need to supply the pathname shown below. You can also disconnect obj from the device with the fclose function. If you issue delete while obj is connected, then the connection is automatically broken. If obj is connected to the device, it has a Status property value of open. If multiple references to obj exist in the workspace, then deleting one reference invalidates the remaining references. Because you cannot connect an invalid serial port object to the device, you should remove it from the workspace with the clear command. When you delete obj, it becomes an invalid object. Set(plotGraph2,'XData',time,'YData',data(1,:)) Д¬lear count dat delay max min plotGraph plotGraph1 plotGraph2 plotGrid.Delete (serial) (MATLAB Functions) MATLAB Function ReferenceДЄ serial port object or an array of serial port objects.

Set(plotGraph2,'XData',time(time > time(count)-scrollWidth). The list shows all the serial ports you can access on your computer and can use for serial port communication. 'YData', data(2,time > time(count)-scrollWidth)) Set(plotGraph1,'XData',time(time > time(count)-scrollWidth). 'YData', data(3,time > time(count)-scrollWidth)) Set(plotGraph,'XData',time(time > time(count)-scrollWidth). The object does not use this data directly, but you can access it using the get function or the dot notation. Configure UserData to store data that you want to associate with a serial port object. However, because of the time it takes to do fscanf(), you can't obtain and plot a signal in real time faster than every 50ms or so without aliasing. Data you want to associate with a serial port object, specified as a MATLAB array.

If you still need assistance, here is my modified version of the code I used to plot three data lines from an accelerometer. Hot Network Questions Flatten simple list Can comparison operator be defaulted outside of class definition in. I actually used the code from the same source you are for one of my projects. Reading data from Arduino in Matlab through serial port. I need to plot all the 3 datas (data, data2, data3) on the graphic with different colors. %Close Serial COM Port and Delete useless VariablesД¬lear count dat delay max min baudRate plotGraph plotGrid plotTitle s. Therefore, many of the commands in the example are specific to this instrument. The instrument is a Tektronix TDS 210 two-channel oscilloscope connected to the serial port COM1.

Set(plotGraph,'XData',time,'YData',data) This example illustrates how to communicate with a serial port instrument by writing and reading text data. %set(plotGraph,'XData',time(time > time(count)-scrollWidth),'YData',data3(time > time(count)-scrollWidth)) %plot(time(time > time(count)-scrollWidth),data3(time > time(count)-scrollWidth)) ДЄxis() Set(plotGraph,'XData',time(time > time(count)-scrollWidth),'YData',data3(time > time(count)-scrollWidth)) ScrollWidth = 10 % display period in plot, plot entire data log if 0) Define serial port with a baud rate of 115200 rate 115200 if ispc s serial(COM1, BaudRate,rate) elseif ismac Note that on OSX the serial device. XLabel = 'Elapsed Time (s)' % x-axis label PlotTitle = 'Serial Data Log' % plot title Here is the matlab code that I'm using to plot one of the data: clear I also managed to plot one data at a time with some code I found on mathworks and modified it a bit, which does not suit my project. so now I have 3 datas that I want to plot (data, data2, data3) in real time ON THE SAME GRAPHIC. My application reads data from sensors trough an ARDUINO UNO platform and then trough serial port I managed to read all the data that I need in MATLAB.
