I am facing a problem related to the visualization of input data in the ReadFromFile Expression area. When I set the time step to 'Annual' and enter data for both Demand and Head Flow, no plot of the input data is generated in the ReadFromFile Expression window. However, when I change the time step to 'Monthly' using the same dataset, a plot appears.

Could anyone please clarify whether it is acceptable to proceed without the input data plot in the ReadFromFile Expression area when using the annual time step, or if this indicates a potential issue in my setup?

Any guidance or suggestions will be greatly appreciated.
