Plot specific columns in cell array

Hello,

I'm new to MATLAB and still learning :) I've been struggling with one such command execution.

I have a cell array c28_20chs which has 5 cells inside it as shown in the picture. I need to navigate to the individual cells and then plot col 3,4 together as x anf y axis.

Is there any structured command for it? I would really appreciate if any one could guide me.

for i=1:numel(c28_20chs)
  hL(i)=plot(c28_20chs{i}(:,3),c28_20chs{i}(:,4));
  if i==1, hold on; end
  if isempty(c28_20chs(i)), continue, end
end

Hello dpb.

Thanks for the code. Its indeed plotting the data, but i get an error-"Index in position 2 exceeds array bounds". What is this about?

Also can you please provide me a link to the -"background info on cell arrays for examples and explanation of dereferencing cell arrays" or suggest some keywords for me to find the correct info :)

Thanks!

Paste the error in context -- not having your data can't duplicate here.

As for the information on cell arrays, start with

doc cell

It has examples; there's also the links under "Topics" at the bottom of the page, one of which is titled <Access Data in Cell Array>.
