Hello. I am trying to plot with different colours (2D plot). I have an index 1 : 46, and for each array, I want a different colour.
Thanks.
figure
hold on
for ind=1 : 46,
plot(plane_des2(ind).Altitude, plane_des2(ind).IAS,'.');
xlabel('Horizontal Displacement');
ylabel('Unfiltered Airpseed');
title('Airpseed vs Displacement')
end
hold off

It doesn't have to be different colours. I just want to be able to tell the difference between the plots of each indexes. Thanks.

There is an enhanced plot routine in the file exchange that can use combinations of values to make multiple lines more visible; unfortunately I do not recall the submission name at the moment. One that would help would be http://www.mathworks.com/matlabcentral/fileexchange/47921-plotpub-publication-quality-graphs-in-matlab
In the meantime:
maxind = 46;
colortab = jet(maxind); %distinct colors
figure
hold on
for ind=1 : maxind,
plot(plane_des2(ind).Altitude, plane_des2(ind).IAS,'.', 'Color', colortab(ind,:));
if ind == 1 %save time on the rest
xlabel('Horizontal Displacement');
ylabel('Unfiltered Airpseed');
title('Airpseed vs Displacement');
end
end
hold off
