Hi there i have a for loop plotting multiple lines on the same graph, with the help of @Marius I have managed to get each line a different color in a color scheme (jet). However how can I add a colorbar to the plot? I have tried myself right at the end of the script but its not working?
function TempSalplot(datafile)
datafile=importdata(datafile);
A=datafile.data; %depth,distance,salinity,temp are in column 28,2,14,11 of datafile respectively;
figure;
for z=[1:3:max(datafile.data(:,28))]; %max is around 16
col = jet(z);
for depthi=[1:length(A(:,28))];
if A(depthi,28)>z-0.5 & A(depthi,28)<z+0.5;
B(depthi,1)=A(depthi,2);
B(depthi,2)=A(depthi,14);
B(depthi,3)=A(depthi,11);
B(all(B==0,2),:)=[];
[C,ia,idx]=unique(B(:,1),'stable');
val=accumarray(idx,B(:,2),[],@mean);
M12=[C val];
[C,ia,idx]=unique(B(:,1),'stable');
val=accumarray(idx,B(:,3),[],@mean);
M13=[C val];
M=[M12,M13(:,2)];
end
end
plot(M(:,2),M(:,3),'.-','color',col(z,:));
xlabel('Salinity (psu)');
ylabel('Tempurature (degC)');
hold on
end
h=colorbar('ticks',[1:max(z)]); %This doesn't seem to be working?
caxis([1,max(z)]);
end
The colors in the colorbar just dont match the colors on the graph? Print screen of figure -->http://prntscr.com/8qecy1

just a quick glance so not sure if this is what you are looking for but you should put the call to create the colors of jet outside of your for-loop
figure;
col = jet(max(datafile.data(:,28)));
for z=[1:3:max(datafile.data(:,28))]; %max is around 16
