Hello Frank, thanks for using LatencyMON! The min y (the 0 on the y-axis) is calculated based on ALL the charts, this removes from the y-axis the values which are the same for all the charts and leaves the different part intact. In fact, the Y-axis is always the same across all the charts. This serves exactly the purpose of allowing comparison at a glance!
