How do I give the legends for two different values, those individually are calculated multiple times?

I have percentage value graph of two values dependent on the laser angle. These two values are calculated multiple times. I tried to give the legends by the command legend('per Tape irradiated','per substrate irradiated'), but then both the legends are given with the same color. I want to have the corresponding legends according to the percentage of Tape and Substrate irradiated. Percentage Tape irradiated should be blue and percentage of substrate irradiated should be blue.

"These two values are calculated multiple times" - this does not allow to reproduce the problem. Please post some minimal code, which causes the same effect. Otherwise posting an answer will require guessing, what you exactly do.

Well, I'll guess... :) You're calculating the red set of results first, then the blue and then only pass two label strings to legend; hence you label the first two lines which are both red. You need to save the line handles to at least the first red and first blue calculation and then use those handles to associate the labels to the appropriate handle with the alternate legend syntax

"legend(subset,__ ) only includes items in the legend for the data series listed in subset. Specify subset as a vector of graphics objects. ..."
