| The Wave API provides a few methods for reading time series from files, manipulating and displaying them. | | The BlueM.Wave API provides methods for reading time series from files, manipulating and displaying them. |
| | |
| To access the API, include a reference to Wave.exe (or to the Wave project if you have the source code) in your .NET project.
| |
| | |
| Below are some examples.
| |
| | |
| ==Example1==
