Plot a discrete wavelet scalogram:

The vertical axis represents refinement level and the horizontal axis represents time:

Use Full ticks to expand the labels on the vertical axis:

Specify wavelet indices to plot:

Show wavelet transform as a tree:

The second argument is used to specify wavelet indices:

Scale wavelet coefficients before plotting:

The third argument is used to specify a scaling function:

A scalogram gives a visual representation of a wavelet transform:

Perform a wavelet transform:

Darker colors indicate larger coefficients and lighter colors indicate smaller coefficients:

Use WaveletListPlot to complement a scalogram:

Color variations in the scalogram can be better visualized using WaveletListPlot:

WaveletScalogram works on DiscreteWaveletData generated from any transform:

Plot a scalogram for DiscreteWaveletTransform and DiscreteWaveletPacketTransform:

Plot a scalogram for StationaryWaveletTransform and StationaryWaveletPacketTransform:

Plot a continuous wavelet scalogram:

The vertical axis represents scales and the horizontal axis represents time:

Use Full ticks to expand the labels on the vertical axis:

Specify wavelet indices to plot:

The second argument is used to specify wavelet indices:

Scale wavelet coefficients before plotting:

The third argument is used to specify a scaling function:

A single frequency shows up as a horizontal band at the equivalent scale:

Multiple frequencies show up as multiple bands at the equivalent scales:

The Automatic setting for AxesOrigin is set to {0,0}:

Coordinates for vertical axes start from 0 at the bottom:

Put the axis origin at and , which is indicated by the 5 refinement level:

Blend two colors:

Reverse a color function:

Color by scaled coordinate:

No argument scaling on the left; automatic scaling on the right:

To use ColorFunction with a wider range, set ColorFunctionScaling to False:

Draw a frame around a plot:

Put a frame on specific edges:

Put a frame on left and right edges:

Put a frame on bottom and top edges:

Specify overall frame style, including the frame, frame ticks, and frame tick labels:

Place frame ticks on all the edges:

Use Full ticks to draw labels indicating octaves and voices {oct,voc} on the vertical axis:

Label frame ticks to indicate octaves:

Specify overall frame ticks style, including frame tick labels, using FrameTicksStyle:

Put grid lines across the scalogram:

Specify location for grid lines:

Specify overall grid lines style:

Use a nonlinear raster function as used by MatrixPlot:

Invert wavelet coefficients of DiscreteWaveletData:
