Wave is a tool for displaying, analyzing and importing and exporting time series.


Supported formats

Use a Wave project file (*.wvp) to quickly import multiple series from multiple files at once.

Drag&Drop files onto Wave to import them quickly.

It is also possible to manually input time series, or use copy & paste from Excel.

Visualization & Navigation

Display time series in a highly customizable diagram (provided by TeeChart)

  • Overview: An overview chart shows you the full extent of the time series and the period currently displayed in the main diagram.
  • Axes: When importing time series, series are automatically assigned to different axes depending on their unit.
  • Zoom & pan: Use the mouse to zoom or pan.
  • Navigation bar: Use the navigation bar to set a custom display period and to navigate by a fixed time period.
  • Quickly switch time series on and off using the check boxes in the legend.

Save & Export

Save diagrams to the native TeeChart format (TEN-File) to preserve all data and formatting (for exceptions, see known issues below).

Export diagrams as image files (PNG, JPG, BMP)

Export time series to the following formats:

Edit & Analyze

Editing functions:

  • Cut time series to a specified time period or to another series' extent
  • Convert error values of a time series
  • Merge multiple time series into one while respecting priorities

Analysis functions:


The API is used by BlueM.Opt and BlueM.Win.

See the documentation.


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 after import.
  • NaN values can be visualized in the chart by pressing a button (see screenshot to the right).

Volume property

Wave calculates and displays the volume of a time series (e.g. for GoodnessOfFit analysis or in the properties window), if a time series' unit ends with "/s" (e.g. "m³/s"), by integrating the values over time. Time series with other units only have the Sum property.


Please refer to the Download page.

Known Issues

  • 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
