niHWS Set Wfm Attribute

Sets a particular attribute of a waveform. The instances of this polymorphic VI correspond to the type of attribute you want to set.

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

Set String

Sets the value of text attributes that apply to the waveform specified by the waveform reference.

waveform reference in is a reference to the waveform. Waveforms are identified by reference for purposes of setting and getting waveform attributes and reading and writing data.

attribute ID selects the attribute to retrieve.

Note	A general-purpose text field for any information pertaining to the waveform.
X Axis Label	A general-purpose text field intended for labeling the x-axis of a waveform data plot.
Y Axis Label	A general-purpose text field intended for labeling the y-axis of a waveform data plot.
X Axis Units	A general-purpose text field intended for denoting the units of the x-axis.
Y Axis Units	A general-purpose text field intended for denoting the units of the waveform data.
Valid Signals	The list of bits, or signals, in the samples of a digital waveform that are valid. For example, "0,3,6" means that only bits 0, 3, and 6 of each unsigned long digital sample contain valid digital data. A hyphen may be used to denote an inclusive range of consecutive signals. For example, "2-5" is equivalent to "2, 3, 4, 5". A semicolon may be used to specify valid signals on multiple devices in a 2D waveform. For example, "0-3;0,6,2" would mean bits 0 through 3 on the first row, and bits 0, 6, and 2 on the second row.
Timestamp	A string in the form hour:minutes:seconds.fractional seconds, followed by AM or PM MM/DD/YYYY. This string is intended to serve as the time the waveform was originally acquired.

attribute value specifies the new setting of the attribute specified by attribute ID.

error in (no error) can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

	status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	code identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	source describes the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

waveform reference out is the copy of waveform reference in you use for input into the next NI-HWS VI in your program.

error out passes error or warning information out of a VI to be used by other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

	status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	code identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	source describes the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

Set DBL

Sets floating point attributes that apply to the waveform specified by the waveform reference.

waveform reference in is a reference to the waveform. Waveforms are identified by reference for purposes of setting and getting waveform attributes and reading and writing data.

attribute ID specifies the waveform attribute to retrieve.

X Axis Start	The X value for the first point in the waveform. The Scope Soft Front Panel stores relativeInitialX in this attribute, for example.
X Axis Increment	The period between samples in the waveform. The rate of the Sample clock used to capture the waveform is the reciprocal of the X Axis Increment.
Y Axis Minimum	The minimum value of the y-axis.
Y Axis Maximum	The maximum value of the y-axis.

attribute value specifies the new setting of the attribute specified by attribute ID.

error in (no error) can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

	status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	code identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	source describes the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

waveform reference out is the copy of waveform reference in you use for input into the next NI-HWS VI in your program.

error out passes error or warning information out of a VI to be used by other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

	status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	code identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
	source describes the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
