GANG

Creates hydrograph plots

Input:

1^st line: data identification number, flag for index, free surface and transformation

2^nd line: number of elements/nodes for the hydrograph plot

3^rd line: node or rather element numbers (maximum 10 per line, separated by a blank or a tab) or rather (number < 0) one node per line (x- and y-coordinates, layer number nr). If more than one line is needed, the next lines shift accordingly.

4^th line: colour number for each first curve in a hydrograph plot, number of plots over each other

5^th line: minimum/maximum values, size of interval (if min=max, the program uses the global values)

6^th line: flag for spline-interpolation (1= with interpolation, 0 = without interpolation)

7^th line: flag for all hydrograph curves into one diagram? (1= yes, 0 = no)

8^th line: flag for nominal values (1 = with nominal values, 0 = without nominal values), background colour, scaling factor

With nominal values:

9^th line: colour number for nominal values

10^th line: name of the file which contains the nominal values

Generally, you can represent only transient data (identification numbers between 400 and 500) as a hydrograph plot.

If curves are presented with nominal values the calculated and the nominal values are recorded in an ASCII file (C <Node/element number>. txt) when the plogeo.ini command EDIF = 1 is set.

 

Curves with an additional horizontal line for reference data:

For the case in which each curve is plotted into its own map (7^th line of the GANG-command "all time-series curves into one diagram?"), an additional horizontal line can be plotted into each map (colour number +1). The level for this line is taken from a second identifier at this node/element. Hence, the second identifier must refer to steady-state data. Possibilities are input data (e. g. ground level - identification 85, z-coordinates - identification 13) as well as results at the end of the transient calculation (e. g. potential head - identification 306).
