I want to plot a line between two know points in coordinate.

Like I have two points (1,2) and (3,4). I want to connect them with a line segment.

I try line([2,3],[3,4]) and plot([1,2],[3,4]). Both are set x and y limits not connect them.

Can anyone help?

Thank you

‘How can we add weight to edge after ploting the above line.’

Not sure what that means. Try the 'LineWidth' property to create a thicker line.

You need to plot the x-values in one vector and the y-values in another vector:

plot([1 3], [2 4])

The x-values in your two points are [1 3] and the y-values are [2 4].

put each point in an [x y] vector: p1 = [1 2], p2 = [3 4]. Then plot plot([ p1(1) p2(1)], [p1(2) p2(2)]);
