when I plot an image in point form the direction of Y Axis is changing!
how can I make 0-Y and 0_X in the same position
there is three dimention because I worke on volume image
label=I;
[X,Y,Z]=meshgrid(1:size(label,1),1:size(label,2),1:size(label,3));
label=label>0; % für logischen Eintrag
Data=label; % Für Farbeintrag
ind=Data(:)>0; % keine Null - einträge
px=X(ind);
py=Y(ind);
pz=Z(ind);
color=double(Data(ind));
%% point plot
set(gca,'YDir','normal')
plot3(px,py,pz,'.')
xlabel('X µm')
ylabel('Y µm')
zlabel('Z µm')

[X,Y,Z]=meshgrid(1:size(label,1),1:size(label,2),1:size(label,3));
That is incorrect. size(label,1) is the number of rows, and rows correspond to Y not to X. size(label,2) is the number of columns, and columns correspond to X not to Y.
