Buffers signals and returns the buffered signals up to a maximum count. If you use this VI with the Waterfall Graph, the display mimics the behavior of a chart.

Use the pull-down menu to select an instance of this VI.

SVX Buffer Waterfall Graph (Waterfall Data)

	reset on change to dx specifies whether the buffering VI checks for consistency in dx between the input data and the buffered data. If reset on change to dx (F) is TRUE and the dx of the input data is not equal to the dx of the buffered data, the buffer resets. The default is FALSE.
	reset? clears the buffer. The default is FALSE.
	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.
	number of spectra specifies the maximum number of spectra to buffer for display. number of spectra is similar to the chart history of a chart. The default is 40.
	waterfall graph data out returns an array of 2D waveform signals in three dimensions. You can display this information with the Waterfall Graph. z0 returns the initial value of the first plot on the z-axis. dz returns the interval between plots on the z-axis. plots returns the data on the waterfall graph. x0 returns the initial value on the x-axis. dx returns the interval between points on the waterfall graph. Y returns the values of the points on the waterfall graph.
	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.

	reset on change to dx specifies whether the buffering VI checks for consistency in dx between the input data and the buffered data. If reset on change to dx (F) is TRUE and the dx of the input data is not equal to the dx of the buffered data, the buffer resets. The default is FALSE.

	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.
	initial z0 specifies the initial value of the first plot on the z-axis. initial z0 is ignored after the first plot unless reset? (F) is TRUE.
	dz specifies the interval between plots on the z-axis.

	reset on change to dx specifies whether the buffering VI checks for consistency in dx between the input data and the buffered data. If reset on change to dx (F) is TRUE and the dx of the input data is not equal to the dx of the buffered data, the buffer resets. The default is FALSE.
