How to generate visual graph for classified behaviour?

I have a 285768x1 cell which has word outputs such as 'standing''step' etc which are linked to time. Each row is equal to 0.02s of time. The labels are for IMU data (which is graphed by MATLAB with waveforms). My question is how do i visualise the data?

- create a graph with time and behaviour, to label the waveforms - maybe use one axis of the accelerometer and label it with colour (red when stepping or blue when standing etc). -create a percentage of behaviour recorded? so I can detect activity budgets.

At the moment there are no plots I can perform. Any help regarding how to do this would be much appreciated.

Thankyou!!

Attach your data..it can be done..

Answer 1

Let str be your cell of size 285768x1 having strings. And let A be the corresponding 285768xn data matrix. To visualize the data having a string 'standing' do this:

idx = strfind(str,'standing') ;  % get indices of string standing 
A_standing = A(idx,:) ;  % this gives you whole data with string standing   
pcolor(A_standing) ;    % surf plot 
shading interp 
colorbar

Hi KSSV, thanks for your answer!

I was able to fo the first part for the idx. Which gives me a number labelled for standing. However the second part i get an error: Function 'subsindex' is not defined for values of class 'cell'. Am i doing something wrong?

Thankyou :)

How is A? Do you have a matrix or cell? It depends on how the data is.

[Katrina Anderson]

The time frame is a double, and the orignal data with the 'standing''stepping'is a cell. Then the waveforms are also all double.

Sorry, Im still learning a lot haha

Can you attach your data..with the code you tried.

Thankyou!! i will attach a few files as the entire workspace is too large.

This is the time data.

And this is an example of what my data looks like from the sensor. This is just one acc axis but it might give you a better idea of what im trying to do.

So i used the code you gave me, and i was able to successfully apply the strfind, which gave me a number 1 for each 'standing'. But the A_standing was the error.

>> A_standing = acctime(idx,:) ; Function 'subsindex' is not defined for values of class 'cell'.

is that how im supposed to code it?

Thankyou!!
