help with plotting matrix

I Have to plot my K_tilde_linear matrix that i created where the x values start at 1 and go to 15. The Y values are supposed to be the K_tilde matrix. When i simply type plot(K_tilde_linear) i get my desired graph except it is not a smooth linear curve, it has a bunch of lines going vertically. Can someone help me with this please. Attached is a picture of my current graph as well as my code. Thank you

Not sure if this is what you want or not. Looks like the only values in the matrix are on the diagonal.

plot(1:14,diag(K_tilde_linear));
