Hey everyone,
I have a subplot using this code. How can i change the colormap to instead show increasing "reds" (of the summer colormap) in the y direction instead of the x direction?
if true
% C = subplot(2,1,1);
plot(p2.t,p2.data,'b');hold on
scatter(p2.t,p2.data,sz,c,'filled','d');
B = scatter(DSA.Peak1Theory, DSA.Peak1DataA,'m');
A = scatter(DSA.Peak1DataF, DSA.Peak1DataA,'r');
legend([B,A],build1b,build1a)
colormap(C,summer)
title('DSA Spectra PS Oscillator');xlabel('Frequency (Hz)');ylabel('Amplitude (db*Vrms)');
hold off
end

Show a screenshot, because I don't know what you mean by you want the colormap to go in the x direction instead of the y direction. In fact, it doesn't go in any direction. Perhaps you were referring to the colorbar, but that goes in the y direction already, so that can't be what you were referring to.
Just throwing out a wild guess, maybe you want flipud:
imshow(grayImage);
colormap(gca, flipud(summer(256)));
colorbar;
or another wild guess, just pass the color you want for every marker into scatter(). You can do that you know.
