Excel spreadsheet scatter_plots.xls bundled with NetSTORM includes a macro to produce scatter plots comparing modeled and observed storm volumes, peak discharges, peak velocities and peak depths for each gage location. Plots can be produced by first pasting the contents of the ModGage.xls spreadsheet generated by SWMMReporter (see Step 10 in the SWMM Reporter description), and then running the Excel macro CreateCharts.
