The outer two markers on slide and rotary controls or indicators are the scale limits. Scale limits do not have to match range limits. Scale limits can be a subset of the range of the control or indicator. For example, the default range of a 16-bit signed integer control or indicator is –32,768 to 32,767. However, you can set the data range to –1,000 to 1,000 and then set the scale limits to 0 and 500.

Complete the following steps to change scale limits and increments.

  1. Use the Operating tool or the Labeling tool to click the upper or lower limit on the scale of the slide or rotary object.
  2. Highlight the digits you want to change and type the new number.
  3. Press the <Enter> key, click the Enter button on the toolbar, or click outside the scale to enter the new value. The other limit stays the same and LabVIEW recalculates the increment automatically.
  4. Repeat steps 1 through 3 to change the value of an intermediate marker on the scale. LabVIEW adjusts the increments of the scale automatically.

    If the increments of the scale do not adjust automatically, the intermediate marker is too close to another marker, so you need to increase the size of the slide or rotary object before you change the value of the intermediate marker.

You also can use the Range properties to change scale limits and increments programmatically.
