Hi everybody,

I'm trying to plot something like this, but just for a number of datapoints.

But keep on getting something like this instead:

I've tried using 'line' but doesn't work and also 'bo-' in the plot command. My code at the moment is:

xVal = [Ax, Bx, Cx];
yVal = [Ay, By, Cy];
plot(xVal, yVal,'bo-'), grid on, hold on
line(xVal, yVal)

Any help is appreciated thanks!

I managed to solve it using the following code:

for j = 1:13
    xVal = [Bx(j), Ax(j)];
    yVal = [By(j), Ay(j)];
    
    plot(xVal, yVal,'bo-'), grid on, hold on
    xlim([-0.4 0.4]), ylim([-0.4 0.5])
end

This worked for two points and just created another for-loop for the other two points.

Thanks for the input guys!

I tried something like this, but it's not quite what I'm after.
