You can use to plot the required graphs

c2 = splitapply(@(x) {x}, c(2:end,:), findgroups(c(2:end,end)));

titles = {'accX', 'accY', 'accZ', 'Average'};
for ii=1:4
  f = figure;
  ax = gca;
  hold(ax);
  title(titles{ii});
  for jj=1:length(c2)
      plot([c2{jj}{:,1}], [c2{jj}{:,ii+1}], 'DisplayName', c2{jj}{1,end})
  end
  legend()
end

[Image Analyst]

I think he wanted separate plots for each (not all 4 on the same graph), and for each plot to have different colors in each time segment depending on the word in column 6 (starting, stopping, moving).

[Girish Kanika]

Yes Image Analyst is right I want to see the plot like this as shown in fig

But thankyou people for your responses.

Hi @Ameer Hamza I tried your code I couldn't get how the different activities are getting plotted please refer the following link:

"https://www.mathworks.com/examples/matlab/community/32165-human-activity-classification-based-on-smartphone-sensor-signals#14"

I couldn't get how the "plotAccelerationColouredByActivity(t, acc, actid, {'Vertical acceleration'},actlabels)" this is done.

[Ameer Hamza]

plotAccelerationColouredByActivity(), is not a MATLAB built-in function. This function is part of the Sensor Data Analytics Webinar. In order to use that function, you will need to download and place in MATLAB path.
