If you're less free spirit and more nerd (as Dave Ramsey likes to say) this graphing bundle might be perfect for you.
Want to color code? Do it. Shade things in? That's possible. But more importantly, you'll have a practical and straight-forward summary of the progress you're making whether it's going up or down without it all looking the same.
My favorite feature is there are sheets that start on January and others left blank to fill in how you see fit.
