I feel like this is a simple problem but I can't seem to figure out where I'm going wrong.

This is what I have at the moment:

I'm trying to smoothly intersect with all the coloured boxes, dodging the dark green obstacles. However, my lines keep starting at x = 1, and ending 1 unit too far as well. They also don't intersect well.

Where am I going wrong? Any help is appreciated, thanks.

Hi,

For interpolation of first line you are using 14 points which is Xi= 0:1:13; but I can see only 13 points for 2nd plot which is Xi2=12: -1.0: 0.0;

For intersection, keep your Xi2= 13: -1.0: 0.0;

Since you are interpolating the data, so it smoothens its own and does not provide expected result. To avoid that, you can increase size of X2 and Y2. Try something like,

X2= [13 11 9 7 5 3 0];

Y2= [6 3 1 0.5 1 3 6];

I hope this helps you to get expected result.
