====Bar Charts====

This display in the [[user|Face Display application]] shows a //bar chart// highlighting a particular value across each of the Roof Supports on our demo system.

You can choose which property you'd like to view using the drop-box at the top-left corner.

This chart is **live** - it will animate as new data arrives.

The green box at the top of the chart shows the position of the //shearer//. You'll notice that several variables change as it passes.

===Items of Interest===

The //Relay Bar// value will drop radically behind the shearer as it moves across the face.

Looking at //Pressure// will highlight a faulty support and a //cavity// (an area where the roof is unstable and unsupported).
