A
thermometer gauge is a dashboard indicator that compares an actual value to a target value and compares
them in intervals. The actual value of the primary measure is indicated
by a vertical bar. The target value is indicated by a small black line.
The thermometer gauge requires a primary measure value and a range-based display rule.
A target measure value is optional. The entire vertical bar is colored conditionally
based
on one color from the display rule.
The base of a thermometer
bar should always start at zero. You can set this by defining your
first range display rule to begin at zero. The designer always shows
the base of the bar at the bottom of the thermometer.
