Plot data in matlab

Isn’t that just this —  

Scaled = @(data,Th) [data(:) ones(size(data(:)))] * ([Th 1; 0 1] \ [1; 0]);     % Scale Data By Threshold

Day{1} = [10; 
          30; 
          15];
Day{2} = [20; 
          40; 
          10];

A_Threshold = 70; 
B_Threshold = 80; 
C_Threshold = 85;
Thrshld = [A_Threshold; B_Threshold; C_Threshold];

for k1 = 1:numel(Day)
    for k2 =  1:size(Thrshld,1)
        DayScaled{k1}(k2,:) = Scaled(Day{k1}(k2,:),Thrshld(k2));
    end
end

% Day1 = array2table([DayScaled{1}].', 'VariableNames',{'A','B','C'});
% Day2 = array2table([DayScaled{2}].', 'VariableNames',{'A','B','C'});
% ScaledResult = table(Day1,Day2, 'VariableNames',{'Day 1','Day 2'})

Days = datetime(['03/06/2023';'03/07/2023'], 'InputFormat','MM/dd/yyyy', 'Format','MM/dd/yyyy');
ScaledResult = array2table(cell2mat(DayScaled), 'VariableNames',string(Days), 'RowNames',{'A','B','C'})

x = ones(size([Day{1}],2),1)*(1:size([Day{1}],1));

rgb = 'grb';
cmy = 'cmy';
xtl = {'A','B','C'};
mk = {'s','d'};
cgttt = [0.9 0.5 0.3];

figure
plot(Days, ScaledResult{:,1:end},'.-')
legend('A','B','C', 'Location','best')
