I have no ready to use example. To add progress bar control an a scheme you should create a set of images, for example, for 0%, 10%, … 100% of value. Use these images in Dynamic Picture element. Color can be set according to status of input channel. Currently you can’t set the fill color of a bar, but you can change a border color. Set border color property to Status.
The new scheme engine is under development. We are planning to implement the feature you need.
