I am trying to add the data points used to generate the main effects plot to the plot as well.

%doe_full = xlsread('doe_full.xlsx','A2:AC22');
response_variables = {'...'}'; %this is a long cell, not part of the issue
for i_rv = 1 : length(response_variables)
    [figh,axesh] = maineffectsplot(doe_full(:,8+i_rv), doe_full(:,6:8),'varnames',{'RPM', 'feed rate', 'air pressure'});
    set(axesh,'FontSize',14);
    set(axesh(1).XLabel,'FontSize',18)
    set(axesh(1).YLabel,'FontSize',18)
    set(axesh(2).XLabel,'FontSize',18)
    set(axesh(3).XLabel,'FontSize',18)
    subplot(1,3,2);
    title(sprintf('Main effects of the predictor variables on %s',response_variables{i_rv}),'FontSize',18);
%{    
    for i_pv = 1 : 3
        axesh(i_pv);
        hold on;
        scatter(doe_full(:,5+i_pv), doe_full(:,8+i_rv));
        hold off;
    end
%}
    savefig(sprintf('data/doe_results/maineffects/%02d_%s.fig',i_rv,response_variables{i_rv}));
    hold off
end

The code generates the main effects plots just like it's supposed to. However, adding the scatter plots using the commented out section is not working: I am attempting to use axesh(i_pv) to select the correct subplot and then add the data points using scatter(). However, only a few points are added and they do not appear to be using the existing x-axis.

What am I doing wrong?

One of the problems is that the x axes are not actual data. If you dig through the plot properties, the actual X data is [1,2,3... etc] If you look at the code for the plots, they are using tick labels to replace the 1,2,3... etc. with the data from your groups. So, to add data you will have to determine which x index your plot belongs too. So, if your x data is feed rate 10, the x data you put to your scatter plot is 3. Not very convenient for adding data, but there it is.
