Dear ALL,
Basically i want to generate 4 figure windows each having 8 graphs on it corresponding to the cases when y=[20 50 80 110 140 170 200 230]
For each case i need to get the index of y pass it to each of the last four columns of the table to get the corressponding values and the x coorinate at which they occure. making them now pairs of( x,y) and then make a plot for each 4 columns. I.e plot (x, mean velocity), (x,stdvelocity), (x,mean_pd), (x,std_pd)
I did that for the first case for y=20 and the resulting grapgh was good see attachment.
Please how do i extend that to the remaining columns? perhaps a for loop and how can i pass the yindex to the the table?
attached is my data,first figure and below is my code :
many thanks in advancedataplot.png
Generating the table of average values
Average_Table = table(xcoordinate,ycoordinate,mean_velocity,std_velocity, mean_pd ,std_pd);
for jj = 20 :30 :230
yindex=find(ycoordinate == jj);
% Deleting the first index to eliminat the offset value at y=20
if jj ==20
yindex(yindex==1)=[];
end
% getting the indices corresponding to each case.
newX=(xcoordinate(yindex));
newY =mean_velocity(yindex);
% table of newx and newY
tableXY =[newX newY];
% soting out the table in descending order
sortedtable =zeros(length(tableXY),2);
sortedtable(:,1)=sort(tableXY(:,1));
sortedX = sortedtable (:,1);
for N =1:length(tableXY)
sortedtable(N,2) =tableXY(find(ismember(tableXY(:,1),sortedtable(N))),2);
% sorted Y coordinates
sortedY = sortedtable(:,2);
end
hold on
plot(sortedX,sortedY,'color',rand(1 ,3),'marker','*','DisplayName',['Y =',num2str(jj)]);
xlabel('x position');
ylabel('mean velocity');
legend show
%
drawnow;
end

Is this in any way different to your previous question?

Hello Guillaume, its the same question. the code you proded did run but the out put was not what i expected. i expected 4 plots each with 8 lines. please i guuess not its more understandable since i have my data,first plot and entire code uploaded....
