Hello,

I am using the plot(x,y) for the following:

time = [16;17;18;19;20;21;22;23;0;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15]

y = [value1; value2;...]

When I plot(time,y) I get the following graph: http://imageshack.us/photo/my-images/707/jo9f.jpg/

Does anyone know why that diagonal line is created connecting the x values of the points (23,y) and (0,23) when Matlab plots (23,y) and then (0,y1)?

Why is it that Matlab can only plot sequentially, and is there a way around this?

Thanks!

Andrew

在 MATLAB Online 中打开

[sortedTime sortingIndex] = sort(time);
sortedY = y(sortingIndex);
plot(sortedTime,sortedY)
