The Level Meter display shows a graphic representation of how a current value falls between a minimum and a maximum.
To create a Level Meter display, simply drag it onto a page. Once in place, a single double or integer input can be dragged onto it for display.
The top configuration option allows the specification of the display mode for the meter. There are three options:
Below the type of display, the color for the display can be chosen. This affects the fill color for the Bars and Solid types, and the line color for the Line type. To change the background for the meter, set the background color on the display's Properties panel instead.
The next two options allow specification of the minimum and maximum values for the meter. If the input's current value is outside of this range, the displayed value will be clamped to this range.
The Bar Count option specifies the number of discrete bars to be displayed when the meter is in Bars mode. This option has no effect on Solid or Line modes.
The "Based at 0.0" causes the filled section of the meter to extend from the location of 0.0 to the location of the current value, rather than from the minimum of the meter's range to the current value. This option has no effect when in Line mode.
The "Vertical" option changes how the level meter displays itself. When checked, the minimum value is at the bottom of the display; the maximum value is at the top. When unchecked, the minimum value is at the left of the display; the maximum value is at the right.
There are no run-time usage options for the display. It accepts a single input, which must be a double or an integer.
