Computes a histogram for Signal.

Dialog Box Options

Option Description
Configuration Contains the following options:
  • Number of bins—

    Specifies the number of bins in the histogram. The default is 10.

  • Maximum value—

    Specifies the maximum value to include in the histogram. The default is 3. This is best used with floating-point inputs. The maximum value is not included, so values that match it exactly are not included in the histogram.

  • Minimum value—

    Specifies the minimum value to include in the histogram. The default is –3.

  • Auto Configure—

    Automatically configures the histogram settings based on the input data.

    The Auto Configure button is enabled only after you wire valid data to Signal.
Amplitude Representation Contains the following options:
  • Percent of total—

    Represents the value of each bin as a percentage of the total.

  • Sample count—

    Represents the value of each bin as the number of samples in that bin.
Input Signal

Displays the input signal.

If you wire data to the Express VI and run it, Input Signal displays real data. If you close and reopen the Express VI, Input Signal displays sample data until you run the Express VI again.
Result Preview

Displays a preview of the measurement. The Result Preview plot indicates the value of the selected measurement with a dotted line.

If you wire data to the Express VI and run the VI, Result Preview displays real data. If you close and reopen the Express VI, Result Preview displays sample data until you run the VI again. If the cutoff frequency values are invalid, Result Preview does not display valid data.

Inputs/Outputs

  • cbool.png Reset —

    Controls the initialization of the internal state of the VI. The default is FALSE.

  • cexpdynwdt.png Signal —

    Specifies the input signal. The signal can be a waveform, a real array, or a complex array.

  • cerrcodeclst.png error in (no error) —

    Describes error conditions that occur before this node runs.

  • cbool.png Enable —

    Enables or disables the Express VI. The default is ON or TRUE.

  • iexpdynwdt.png Histogram —

    Returns the resulting histogram.

  • ierrcodeclst.png error out —

    Contains error information. This output provides standard error out functionality.
