To view the hydrograph, first select the objects in Map View or Schematic View, then click the Hydrograph button in Simulation tab. The Hydrograph window will appear.

The hydrographs of selected objects are plotted at the bottom of the plotting area. The figure above is the rainfall plot. These two plots have same time scale. To zoom in, simply scroll the mouse scroll wheel up or draw a rectangle to the area of interest on the plot. To zoom out, scroll the mouse wheel down or select the Un-Zoom or Undo All Zoom/Pan from the context menu. All graph options available from the context menu are described in Table 10-4.
