Through 3rd party software that came with a Matlab plugin, I am able to collect and call data from a file that is being populated in real time. The data being populated includes heart rate, blood pressure and ECG.
I want to know how to plot this live feed. It is being collected in real time, so ideally all 3 data streams should be plotted on the same time axis.
So far, I can call the file intermittently and see the latest data values in column format.
Thank you

Hi, sorry for my delay. I can't change the extension or those parameters.
However, I am able to create variables representing the different channels of data within the file. Can't I just use variables to plot the data?

More details would help. So far, the only thing I can suggest is to check "drawnow".
