2. Ia GGU TIME GRAPH User Manual Page 4 of 57 September 2008 1 Preface The GGU TIME GRAPH program allows management evaluation and graphical visualisation of measured data in the form of hydrographs and contour lines The time component is at the fore front of these considerations For example we can represent long term years gauge measure ments as hydrographs and perform statistical evaluations for the measurement duration If the x and y coordinates of the data points are known the measured data for any given point in time can be visualised as position oriented graphics You can select from the following graphical formats for your data e Hydrographs e Contour lines e Colour filled contour lines e Colour filled 3D graphics Using GGU TIME GRAPH each data point can be allocated up to 50 000 value pairs in the form of a date a time and a corresponding value e g groundwater level Data input is in accordance with conventional WINDOWS operations and can therefore be learned almost entirely without the use of a manual Graphic output supports the true type fonts supplied with WINDOWS so that excellent layout is guaranteed Colour output and any graphics e g files in formats BMP JPG PSP TIF etc are supported DXF files can also be imported by means of the integrated Mini CAD module see the Mini CAD manual The program has been thoroughly tested No faults have been found Nevertheless liability for com
