Plot regression with time

Dear all,
Sorry for the novice question, I have a dependent variable (y) and an independent variable (x). Just to show how these two variables relate to each other I can use plotregression function, however each observation belongs to a different time point and i need to have time factor in my plot to show how the change of these two variables could be related to time. Which plot would you recommend in MATLAB? I would prefer the most visually appealing as my aim is to present my data.
Thanks in advance

A common way to show 2D data is via images. You could have time along one axis, your independent variable x along the other axis, and your dependent variable y as the image intensity. If you don't have all x for all t, then you could fill out the 2D matrix for the missing x,time pairs with TriScatteredInterp(). If the image is nice and smooth, then you might also look to display it with surf() instead of imshow() or image().

Can you just stitch together the 5 images side by side? Or else make a movie (animated gif) where it plays the different time point images over and over?

Probably the first option as it is going to be presented on paper.
