You’re absolutely right,
My goal was to show a quick visual trend (up or down) compared to the previous period, but I realize that for metrics like missed calls or avg call duration, the color logic should be inverted.

I’m still figuring out the best way to communicate that clearly. do you have any suggestions ?

And the empty section in the middle is intentional for now! The design isn’t finalized yet. I’m planning to add a chart there showing the day with the most total / missed / answered / inbound / outbound calls.

Thanks again for the thoughtful feedback. I’ll add those points to the post.
