Including time/itration of progress as heading or index of video

I am trying to create video of movements of agent for which I use videowriter.

I want to include 'time' or 'number of iterations' of simulation progress on video/videowriter obtained from 'gscatter'.

I tried 'text(x ,y, 'num2str(iter))' but this gives the progress of time inside the field along with co-ordinate.

I want this time progress as a heading or on the side of video but not inside the spcae itself.
