I have multiple sets of XY data that look like the following graph, where each set has a different color. The maximum of the blue lines is an error and it should be at the same level as the black and red lines (i.e. around 1.9). The same may appliey to the minimum of the green line, which is erroneous, but it is not as critical as the blue line since at least it shows a monotnous increase. If I calculate the avreage of all values I will be entering spme unwanted error into the whole set, and the maximum of the blue curves will influence that average. How can I automatically make the program decide to bring the blue line also to the same level as the red and black ones?

The Q? is one of fundamental concept -- is it the population of points at each level of C or the correlation of A vs C for each unique set?

if I have correctly interpreted the request
% assuming all the lines have the same
% number of elements
% (numel(blueLine) = numel(redLine) ...
[maxBlueLine,idxMaxBlueLine] = max(blueLine); % locate the position of the incorrect value in the blue line
blueLine(idxMaxBlueLine) = redLine(idxMaxBlueLine); % alternatively one of the following assign the correct value
blueLine(idxMaxBlueLine) = blackLine(idxMaxBlueLine);
blueLine(idxMaxBlueLine) = mean([redLine(idxMaxBlueLine) blackLine(idxMaxBlueLine)]);
