Important: Unity Real Time™ online shows data points violating a statistical process control (SPC) rule with a status of "warning" in orange and data points violating a rule with a status of "reject" in red. Therefore, Bio‑Rad recommends not using orange or red for fill colors as it could make these data points difficult to see.
