I have 32bit floating-point data running at 10kHz I would like to plot in real-time. The microcontroller pcb has only a RS-232 port and no other peripherals that would be useful to output data.

What is the best way to plot this data via Rs-232? Should I use something like labview to plot this on a computer?
 

Lab view And Matlab are good choices

But data transfer rate is an important issue ,RS 232 Doesn't have high speed...
So Actual realtime plotting may be a challenging factor
 

Ok. I'm more familiar with matlab. What is the easiest way to plot input data via rs-232 COM?
 

A Matlab real time plotting example

Once the data has been acquired you can use any of those plotting schemes in matlab
 

I think you can use Baud Rate from 19200 or higher. This will give double the speed of the running data.
 

any examples using rs-232 with matlab? does this require an additional toolbox?
