Converts Waterfall Graph data to Colormap data.

plot type specifies the type of colormap to display.

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 VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Refer to Controlling Error Notification to treat what is normally an error as no error or to treat a warning as an error. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
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. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
Z axis unit label returns the unit label of the z-axis.
