Hi all,

I am plotting a 2D plot using command

plot(X,Y,'-mo',...
    'LineWidth',2,...
    'MarkerEdgeColor','k',...
    'MarkerFaceColor',[.49 1 .63],...
    'MarkerSize',4)

Where X and Y are the array of discreate points. The line joining top point A to point M is expected .later the line from M go directly on point Y depending on the Y height I guess, but I dont want this . I want to see the joining line as A.....G... M-N-O-P-Q.....Y..... as a sequence.

Thanks in advance.

These data point is not constant and not consistent as a different programm generate the data with different time step.
