Qatium simulates the behavior of each network using the EPANET toolkit, which can raise some errors while it is calculating and/or finishing the simulation process without returning the results for all the hours shown in the timeline.

In the hours when there are results, they will be shown on the map, in the asset details, and in the pressure, flow, and tank autonomy panels. But if for a selected time step there are no available results, the graph in the asset detail will be updated and only show results in the time steps with data.

While the simulation is running, the graph is being calculated and drawn. For very large and complex networks, it might take longer to display the network.

Remember that live data graphs are available only when and where readings are available.
