niHWS_SetWfmF64Attribute
C Function Prototype
tHWS_Status niHWS_SetWfmF64Attribute (tHWS_WfmRef wfmReference, tHWS_WfmF64Attributes attributeID, double attributeVal);
Purpose
Sets floating point attributes that apply to the waveform specified by wfmReference.
Parameters
| Name | Type | Description |
|---|---|---|
| wfmReference | tHWS_WfmRef | A reference to the waveform. Waveforms are identified by reference for purposes of setting and getting waveform attributes and reading and writing data. |
| attributeID | tHWS_WfmF64Attributes | The waveform attribute to set.
Defined Values niHWS_Attr_XAxisStart—The X value for the first point in the waveform. The Scope Soft Front Panel stores relativeInitialX in this attribute for example. niHWS_Attr_XAxisIncrement—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. niHWS_Attr_WfmYAxisMin—The minimum value of the y-axis after applying the scaling coefficients. niHWS_Attr_WfmYAxisMax—The maximum value of the y-axis after applying the scaling coefficients. |
| attributeVal | double | The new setting of the attribute specified by attributeID. |
