Plot a 1D signal¶
Plot a basic vector. Then, you can visualize this vector as a continuous line, markers, histogram or compute the time-frequency map or power spectrum density (PSD).
- Mouse wheel : to zoom over the canvas
- Mouse press and hold : to move the center of the camera
- Double click : insert an annotation under the mouse cursor
- <delete> : reset the camera
