Analysis of the place of emotions in the month

It's really interesting to enter your mood for the day! But the only problem is that we enter our emotions and what caused them, without following up. But let's imagine that, for personal analysis purposes, we wanted to know which days in the month we were angry and/or anxious, or which days our emotions were impacted by studies, in order to make a comparison with the rest of the month. An aui feature would be great: it would allow you to choose an emotion or a cause, and have it displayed on the calendar, with the corresponding days differentiated (in red, for example). Be careful to leave the 30/31 days, and differentiate the others, so you can really see how much space it takes up.

Thank you, otherwise the application is top!!
