“plot” function for some repetitive X values

Show older comments
Hi, I would like to use “plot” function for some repetitive X values e.g: 1:10 and again 10:1 but the Y values are differ(in one curve).
I want to show effect of increasing value [1:10] and the decreasing value [10:1] in one figure.*
Could you please let me know what the solution is?
Thanks,

I need help in below plot, my xaxis values = [0 10 20 30 40 50 60 70 80 90 80 70 60 50 40 30 20 10 0]. i want to unfold this graph so that my xaxis must follow the original trend ie 0-->90-->0.

I am not sure if I understand correctly.. is this what you are looking for?
myTicks = 1:20;
y = rand(1,length(myTicks));
plot(myTicks,y)
set(gca, 'xTick', myTicks);
% Modifying Tick Labels in X-axis
myTicks(myTicks > 10) = 10:-1:1;
set(gca, 'xTicklabel', myTicks)

Update after comment.
Let X be a matrix with two columns and the values in your comment:
plot(X(:,2))
set(gca, 'xTick', 1:size(X,1))
set(gca, 'xTicklabel','')
h = get(gca, 'XLabel');
set(h,'Units','data');
pos = get(h,'Position');
y = pos(2);
hLabels = zeros(1,size(X,1));
labels = num2str(X(:,1));
for i = 1:size(labels,1)
hLabels(i) = text(i,y,labels(i,:));
end
set(hLabels,'Rotation',45,'HorizontalAlignment','right')
Or you can do:
plot(X(:,2))
set(gca, 'xTick', 1:size(X,1))
set(gca, 'xTicklabel', num2str(X(:,1)))

Are you sure you are typing it correctly? Copy and paste this example. It should work fine.
X = rand(10,2);
plot(X(:,2))
set(gca, 'xTick', 1:size(X,1))
set(gca, 'xTicklabel','')
h = get(gca, 'XLabel');
set(h,'Units','data');
pos = get(h,'Position');
y = pos(2);
hLabels = zeros(1,size(X,1));
labels = num2str(X(:,1));
for i = 1:size(labels,1)
hLabels(i) = text(i,y,labels(i,:));
end
set(hLabels,'Rotation',45,'HorizontalAlignment','right')

What effect do you want? You can always split them and plot them separately.
x=1:10;
y1=2*x+10;
y2=x.^2;
x=[x x];y=[y1 y2];
plot(x,y)
If you don't like the line from x=10 to x=1, replace the last line with,
plot(x,y,'r*');
To split:
idx1=1:10;
idx2=11:20;
figure;
plot(x(idx1),y(idx1),'r',x(idx2),y(idx2),'b');
