+From the "Node" layer you can plot level or storage on Basin nodes.
+From the "Edge" layer you can plot flow over flow edges.
+Note that before switching between these, you typically have to click "Clear" to clear the selection.
+If you run a simulation with the model open in QGIS, you have to close and re-open the "iMOD Time Series Plot" panel for the new results to be loaded.
