Can you elaborate what do you mean by real time data?

RUDRAKSH 2016-5-28

I have a matrix which i have already plotted on a figure. that plot has time on x axes and my desired variable on y axes.

Now on my HIL Simulation i want to follow that data points. Hence i will be getting a value at a defined time steps and i want to plot that data point at the same plot.

在 MATLAB Online 中打开

FileInfo = dir('YourFileWithExtention');
TimeStamp = FileInfo.date;

The above code gives information about your file. You track the TimeStamp, once the file gets updated/ new data added into it, the timestamp changes; then you can read the uploaded data and plot in MATLAB figure to the existing plot.
