I came across strange problem in matlab, i did a simple line plot using following code in a loop. i want to draw the line joining the markers. in principal it ishing , but the plot is just showing markers not joined by the line. I also t style property seperately, but did not work. Wonder what is preventing matlab to draw the line in plot
plot(x,y,'--o')

"I wonder if something is preventing plot command to draw a line."
Your code. My guess is that you are plotting scalar values in a loop, which will show individual markers unconnected by a line.
If you want to have markers joined by lines then you must provide plot with vectors/matrices of data.
In the unlikely event that you really are calling plot just once then please click the paperclip button to upload the exact data vectors/matrices that you call it with, all saved in one .mat file. And show us the exact code used.

In practice this means
- within the loop use indexing to add the data to a vector/matrix,
- after the loop call plot once with that complete vector/matrix.

Another alternative would be to create an animatedline before the loop and addpoints to it inside the loop.
axis([0 360 -1 1]);
h = animatedline;
for x = 0:360
addpoints(h, x, sind(x))
drawnow expose
end
You can specify property values for animatedline like Marker, LineStyle, Color, etc. when you create it.
