Short Description of Functionality

display of a time serie
display of a correlation
display of a frequency distribution

The program TTpegel is able to plot and analyse tidal high or low water level time series of different gauging stations. Analysis means correlation between different gauging stations and frequency distribution (histogram). The data come from a file of type pegelall.dat.

Input-Files

  1. File with tidal high and low water levels (height and time of occurrence) at different gauging stations (file type pegelall.dat)

Output-Files

  1. screen dumps to file of type bmp, eps, jpg, png or tif.

Methodology

After reading a file of type pegelall.dat with tidal high and low water levels and times of occurrence at different gauging stations the program is able to do the following:

  • display of time series for the active and reference gauging station
  • display of correlation between active over reference gauging station
  • display of frequency distribution (histogram) for the active gauging station

At the beginning of the program time series will be displayed. The user can change the function of display interactively via GUI.

The user has several choices:

  • change the active gauging station
  • change the reference gauging station
  • change between tidal high or low water
  • narrow down the time axis to a desired time frame
  • narrow down the times of occurrence to a specific set of days inside the time frame
  • narrow down the times of occurrence to a specific set of months inside the time frame
  • display or hide a legend
  • display or hide a linear regression (time series or correlation only)
  • display or hide a normal distribution function (histogram only)
