Hi all,

Im very new to Matlab and im trying to create a looop that plots the following

scatter(MCR_full.MIB035.Reaches.R32.kin(:,1),MCR_full.MIB035.Reaches.R32.kin(:,3))

scatter(MCR_full.MIB035.Reaches.R41.kin(:,1),MCR_full.MIB035.Reaches.R41.kin(:,3))

scatter(MCR_full.MIB035.Reaches.R88.kin(:,1),MCR_full.MIB035.Reaches.R88.kin(:,3))

scatter(MCR_full.MIB035.Reaches.R90.kin(:,1),MCR_full.MIB035.Reaches.R90.kin(:,3))

scatter(MCR_full.MIB035.Reaches.R100.kin(:,1),MCR_full.MIB035.Reaches.R100.kin(:,3))

all on one plot

Any help with this would be fantastic thanks so much

How is this any different than what I showed you here:

https://www.mathworks.com/matlabcentral/answers/1564796-how-do-i-plot-different-fields-of-a-structure-in-a-loop#answer_809531

% Create sample data
MCR_full.MIB035.Reaches.R32.kin = rand(100, 3)
MCR_full.MIB035.Reaches.R33.kin = rand(100, 3)
MCR_full.MIB035.Reaches.R34.kin = rand(100, 3)
MCR_full.MIB035.Reaches.R41.kin = rand(100, 3)
MCR_full.MIB035.Reaches.R100.kin = rand(100, 3)
% Get all the fieldnames.
fieldNames = fieldnames(MCR_full.MIB035.Reaches)
% Get data from each field and plot it.
for k = 1 : numel(fieldNames)
    thisFieldName = fieldNames{k};
    fprintf('Plotting %s.\n', thisFieldName);
    thisArray = MCR_full.MIB035.Reaches.(thisFieldName).kin;
    x = thisArray(:, 1);
    y = thisArray(:, 3);
    % Unique, random color for each.
    thisColor = rand(1, 3);
    % Do the scatter plot
    scatter(x, y, 30, thisColor, 'filled');
    hold on; % Don't let subsequent plots blow away earlier ones.
end
grid on;
