@idefix37 yes, you got the point.

@Polina-Nozdrina thanks for the prompt reply, it's basically in all the charts, moving through the time by the slider is not "accurate" like an arrow button is if you want to do steps by a single hours, i mean especially with small screens and in a marine environment with the boat moving because of the waves, it's easy to not be accurate and jump by couple of hours instead of one by one. For example happen to me that i whish to move by one hour back but for the reasons above i do slide for two, so i need to move one fwd again and, especially when the connection is not great, there's an uncertainness between the time of the slider position and the chart displayed. Hope i've been able to explain myself.

Hello, is there a way to see the back and forward arrows to do time steps one by one? play/pause button is ok to go forward but then the use of the time bar to get back is quite hard to manage, especially with mobile devices.
