Get the forecast for tomorrow while you still have time to make changes. Correl already shows you the correlation between your habits and your mood. Now you can leverage that data to predict the future. If the forecast is good you have encouragement to keep doing things that are working. If it doesn't look great you can take action today and set yourself up for success.
You already know how your habits are correlated with your mood. Now you can see how they are correlated with each other. Heard of "habit stacking"? Maybe you'll find that taking a walk today is closely tied to how many calories you eat tomorrow. If losing weight is your primary goal you'll be glad to know what other habits are linked to it.
