SVX Convert Waterfall to Colormap VI

Owning Palette: Transient Spectra VIs

Requires: Sound and Vibration Toolkit

Converts Waterfall Graph data to Colormap data.

The SVX Convert Waterfall to Colormap VI will convert the specified array of 2D waveform signals and return the information plotted in a Colormap of spectral results as an intensity graph.

plot type specifies the type of colormap to display. The default is Frequency-Time.

0Frequency-Time (default)—Displays the time on the x-axis and frequency on the y-axis.
1Time-Frequency—Displays the frequency on the x-axis and the time on the y-axis.
2Order-Time—Displays the time on the x-axis and the order on the y-axis.
3Time-Order—Displays the order on the x-axis and the time on the y-axis.
4Frequency-RPM—Displays the RPM on the x-axis and the frequency on the y-axis.
5RPM-Frequency—Displays the frequency on the x-axis and the frequency on the y-axis.
6Order-RPM—Displays the RPM on the x-axis and the order on the y-axis.
7RPM-Order—Displays the order on the x-axis and the RPM on the y-axis.
waterfall graph data specifies an array of 2D waveform signals in three dimensions.
z0 specifies the initial value of the first plot on the z-axis.
dz specifies the interval between plots on the z-axis.
plots specifies the data on the waterfall graph.
x0 specifies the initial value on the x-axis.
dx specifies the interval between points on the waterfall graph.
Y specifies the values of the points on the waterfall graph.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
colormap returns the spectral results converted from the waterfall data. You can display this cluster as a Colormap to show the transient results on an intensity graph with a rainbow color scale.
spectral map returns the 2D array of magnitude data converted according to the scaling parameters.
X scale returns the scaling information associated with the first index of the 2D spectral map.
offset returns the x value associated with elements (0, n) of spectral map.
multiplier returns the x-axis spacing between consecutive elements in a column.
Y scale returns the scaling information associated with the second index of the 2D spectral map.
offset returns the y value associated with elements (n, 0) of spectral map.
multiplier returns the y-axis spacing between consecutive elements in a row.
attribute returns additional information about the spectra. LabVIEW uses this information to display the data properly and to perform extended measurements.
X axis unit label returns the unit label of the x-axis.
Y axis unit label returns the unit label of the y-axis.
error out contains error information. This output provides standard error out functionality.
Z axis unit label returns the unit label of the z-axis.
