WaveletListPlot
WaveletListPlot[dwd]
plots wavelet transform coefficients in the DiscreteWaveletData dwd.
WaveletListPlot[dwd,wind]
plots wavelet transform coefficients corresponding to the wavelet index specification wind.
WaveletListPlot[dwd,wind,func]
applies func to coefficients before plotting.
WaveletListPlot[{dwd1,dwd2,…},…]
plots wavelet transform coefficients from several DiscreteWaveletData objects dwd1, dwd2, ….
Details and Options
- WaveletListPlot works for DiscreteWaveletData coming from 1D array data.
- The wavelet index specification wind is the same as used by DiscreteWaveletData.
- WaveletListPlot[dwd] is equivalent to WaveletListPlot[dwd,Automatic].
- WaveletListPlot has the same options as ListPlot, with the following additions and changes: [List of all options]
-
AspectRatio Automatic ratio of height to width Joined True whether to join points Method Automatic what method to use PlotLayout "CommonXAxis" what layout to use for the plot PlotRange All range of values to include - The following settings for PlotLayout can be used to display multiple sets of data:
-
"CommonXAxis" coefficients are plotted against a common axis "CommonYAxis" coefficients are plotted using a common axis - With the setting "CommonXAxis", coefficients are plotted against a common horizontal axis where the independent axes are separately scaled to occupy the same amount of vertical space.
- With the setting "CommonYAxis", coefficients are plotted using a common vertical axis where the independent axes are separately scaled to occupy the same amount of horizontal space.
- Ticks and FrameTicks have the following settings with special interpretations in the direction perpendicular to the common axis:
-
Automatic refinement level Full full wavelet index - With the setting Method->"InverseTransform", the inverse transform of each coefficient array will be plotted.
- WaveletListPlot returns a Graphics object.

Use PlotLayout->"CommonXAxis" to identify structure, such as edges in coefficients:
Detail coefficients {…,1} are sensitive to edges:
Use PlotLayout->"CommonYAxis" to compare scale of coefficients:
Compare scale of constant and oscillatory parts:
Identify changing relative scale of coefficients:
Constant coefficient {…,0} dominates early and first detail coefficient {1} dominates later:
Compare clean data with data plus noise with a nonzero mean:
Plot multiple sets of coefficients on the same WaveletListPlot:
Highpass coefficients {…,1} are nearly the same, while lowpass coefficient {…,0} is different:
Properties & Relations (5)
WaveletListPlot plots vector wavelet coefficients with a common horizontal or vertical axis:
dwd[…,"ListPlot"] gives each coefficient as a separate list plot:
By default, WaveletListPlot shows the Automatic coefficients used in the inverse transform:
