Hi,
If you don't have the handles of the plot in the figure here is a demonstration for you.
Please read the comments carefully.
%% demo data preallocation
n = zeros(1,12);
x = cell(12,1);
y = cell(12,1);
hFig = figure;
% randomly creating x and y data and plotting
for i = 1:12
n(i) = randi(20,1,1);
x{i} = rand(n(i),1);
y{i} = rand(n(i),1);
hAxes{i} = subplot(6,2,i); % hAxes axis object handles in a cell array (12 handles you have)
hPlot{i} = plot(hAxes{i},x{i},y{i},'LineStyle','none','Marker','*'); % hPlot plot line object handles (12 handles you have)
end
% -------------------------------------------%
% Gathering data from plotted figure
%% FIRST OPTION IN CASE YOU HAVE HANDLES
%% If you know the position use this: (That I choose the 6th position)
myPlotHandle = hPlot{6};
xdata = myPlotHandle.XData;
ydata = myPlotHandle.YData;
% You can also use this from the position: (Axes' children is a plot line object. Our hPlot{6} is hAxes{6}.Children )
xdata = hAxes{6}.Children.XData;
ydata = hAxes{6}.Children.YData;
%%% OR %%%
%% SECOND OPTION IN CASE YOU DON'T HAVE THE OBJECT HANDLES
% click to a point or a data line in the axis. You should click on a data
% plotted.
% run the code below: (gco function gets you the current object(that means last focused or last clicked object), in this case that will be your plot handle like above)
myPlotHandle = gco;
xdata = obj.XData;
ydata = obj.YData;
% you can click for each 12 plot data and run the code so you will get them
% one by one.
