Hello everyone I got the following problem.
I loaded an image into MatLab now the image has a matrix of 720x752x3
I have a Data matrix that is 10x2
I want to plot the datapoints into my image but when I use normal plot I get an error that my data has more than 2 dimensions. Does anyone have an idea how to fix that?
Thanks for helping me

Ahhh, now things are tidy again ;)
@ Andre589 I'd be glad to help but I agree with Jan that we need to see your code.

clear all
close all
I = imread('test.png');
imshow(I)
C = [115 182
225 113
328 58
515 426
422 460
309 535
100 150
478 628
322 411
490 541 ];
plot(C,?)
The result should look like I get the data points I have in my Matrix C into my image I

I'm guessing that you want to plot the coordinates listed in C on top of the image.
I = imread('test.png');
imshow(I)
axis on %this will show you the axis ticks; note the y axis is reversed!
hold on
plot(C(:,1), C(:,2), 'bx')
