Hello, I have a scatterplot that I need to save as .txt file and am confused as how to do so. My code is as follows:
data1 = readtable('600psi_15k_FT.txt');
data2 = readtable('1000psi_10k_FT.txt');
x1=data1.Var1;
y1=data1.Var2;
x2=data2.Var1;
y2=data2.Var2;
[peaks,locs]=findpeaks(y2,MinPeakHeight=0.003,MinPeakProminence=0.0006)
figure;
hold on;
plot(x1, y1, 'b-', 'DisplayName', '600psi');
plot(x2, y2, 'r-', 'DisplayName', '1000psi');
plot(x2(locs), peaks, 'ro', 'MarkerFaceColor', 'r', 'DisplayName', 'Peaks');
legend show;
hold off;
other_peaks = y1(locs);
scatter(peaks,other_peaks);
plot(peaks,other_peaks,'-o')

You have all the information available already in (x1,y1) and (x2,y2) and the findpeaks output.
That is apparently all the information available.
What else do you want from the plot calls?
