MATLAB: How to connect dots on graph

MATLABplotting

I have a code that holds some energy values for some n states(n=1,2,3,4,5… etc) I want to connect these values for same n numbers. However, I have values by second variable which is E-field (=0.1 , 0.2 , 0.3… etc). I need to plot Energy values vs E-field. So i can only plot the values as dots. how can i connect them as i show in picture?
Here's my code that only plot dots:
