How is your data? How you want the plot? There are various ways to display the data in MATLAB.

datta is all large numbers eg vec1 = [115600, 765840, 123423] vec2 = [115100, 765440, 543245] vec3 = [123600, 763210, 324323]

ant all im trying to do is get a lone graph to show each population at a certain year value but i cannot get any results plotted

I think you have to make year vector to plot your data, like:

vec1 = [115600 765840 123423];
vec2 = [115100 765440 543245];
vec3 = [123600 763210 324323];
year = [2000 2005 2010];
figure
plot(year,vec1)
hold on
plot(year,vec2)
plot(year,vec3)
legend({'vec1','vec2','vec3'})
