Numeric Controls and Indicators

Use numeric controls and indicators on the front panel to enter and display numeric data in LabVIEW applications. The following list describes the common use cases of numeric controls and indicators available on the Modern, NXG Style, Silver, System, or Classic subpalettes:

Note��The availability of numeric controls and indicators may vary depending on the subpalette style you choose. Refer to the Modern, NXG Style, Silver, System, or Classic subpalette for numeric control and indicator availability.
Numeric Control or Indicator Description
Numerics Use to enter or display numeric data.
Time Stamps Use to send or retrieve a time and date value.
Fill Slides Use to display numeric data in a vertical or horizontal slide with a customizable scale.
Pointer Slides Use to display numeric data in a vertical or horizontal slide with a customizable scale and a pointer that helps you see the exact value.
Progress Bars Use to show progress in a vertical or horizontal bar.
Graduated Bars Use to show progress in a vertical or horizontal bar with customizable dividers to help you break up the value into equal parts. For example, you can show that a value has reached 25% of the target value.
Knobs, Dials, Meters, and Gauges Use to enter or display numeric data in a rotary action.
Tanks and Thermometers Use to display numeric data in a vertical slide that resembles a real tank or thermometer instrument.
Scrollbars Use to display numeric data in a vertical slide that scrolls through data by dragging the square scroll box, scrolling the mouse wheel, clicking the increment and decrement arrows, or clicking empty space in the scrollbar.
Color Boxes Use to display a color that corresponds to a specified value. For example, you can use color boxes to indicate different conditions, such as out-of-range values.
Color Ramps Use to display numeric data with colors. As the input value changes, the display changes to a previously chosen color for the value.
Waveforms Use to enter or display numeric data in a waveform.
Tip��Replace an existing value in a numeric control or indicator with a new value by pressing the <Enter> key, clicking outside the digital display window, or clicking the Enter button. While the VI runs, LabVIEW waits until you perform one of these actions to interpret the new values. For example, while changing a value in the digital display to 135, you do not want the VI to receive the values 1 and 13 before 135.
Note��To retain the floating-point representation, LabVIEW adds any necessary prefixes to the unit string when you format a numeric control or indicator in an engineering or System International (SI) notation and do not have a complex representation.
