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.
You can change scale limits interactively or programmatically.
Complete the following steps to change scale limits and increments.
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.
