Wave calculates and displays the Volume property of a time series (e.g. for [[Wave:GoodnessOfFit|GoodnessOfFit]] analysis or in the properties window), if a time series' unit ends with "/s", "/min", "/h" or "/d" (e.g. "m³/s", "mm/h", etc.) and its interpretation is either Instantaneous, BlockLeft or BlockRight, by integrating the values over time while respecting the interpretation. Time series with other units or interpretations only have the Sum property. NaN nodes cause the adjacent timesteps to not contribute to the volume (depends on the interpretation).

It is also possible to manually Icon chart line edit.png enter time series, or Icon page paste.png paste clipboard data from Excel and Talsim-NG.

Comandline interface

Wave has a commandline interface for importing and converting time series, see Wave:CLI for details.

API

The API is used e.g. by BlueM.Opt and BlueM.Win but allows using Wave from within any .NET project.

See the API docs here: https://bluemodel.github.io/BlueM.Wave/api/

Notes

Error values

Visualization of NaN values
  • "NaN", "Infinity" and "-Infinity" in import files are recognized and accepted.
  • Unreadable values are converted to NaN during import.
  • If a file format has a specified error value (e.g. -777 for ZRXP and UVF), then any corresponding entries are also converted to NaN.
  • NaN values are displayed as gaps in the chart and are ignored when performing analysis functions.
  • Custom, user-specified values can be converted to NaN Icon error convert.png after import.
  • NaN values can be visualized in the chart by pressing a Icon chart line error.png button (see screenshot).

Volume property

Wave calculates and displays the Volume property of a time series (e.g. for GoodnessOfFit analysis or in the properties window), if a time series' unit ends with "/s", "/min", "/h" or "/d" (e.g. "m³/s", "mm/h", etc.) and its interpretation is either Instantaneous, BlockLeft or BlockRight, by integrating the values over time while respecting the interpretation. Time series with other units or interpretations only have the Sum property. NaN nodes cause the adjacent timesteps to not contribute to the volume (depends on the interpretation).

Supported date range

Wave supports dates between 01.01.0001 and 31.12.9999.

The chart display can only show dates between 01.01.0100 and 31.12.9000. Time series with dates before 01.01.0100 and after 31.12.9000 are cut for display purposes, but all nodes are still available for analysis and export and are shown in the properties and time series values dialogs. (#68)

Downloads

Known Issues

  • When saving a chart to the native TEN format of TeeChart, certain Timeseries properties such as Interpretation, Datasource and sometimes Unit are lost.
  • When saving a chart to the native TEN format of TeeChart, any NaN values contained in the series are lost (i.e. the nodes with the NaN values are omitted from the series). fixed in v1.9.1
