To display some parameter value as a linear or circle graph indicator you can use either series of individual LEDs arranged in the shape you need (circle or line) or ready-made LED bar graphs.
When assigning the LEDs you need to choose the "LED Bar Indicator" option in the plugin configuration window, select only the output number to which the first LED will be connected and insert the number of LEDs (sectors) your indicator includes.
The number of LEDs (sectors) in your indicator is limited only by the number of registers or drivers in the chain.In the first diagram, a 10-sector LED bar is connected to HC595 register chain outputs #2–11, and the remaining outputs are used for individual LEDs. The second diagram shows a 6-sector LED bar connected to LED driver outputs #10–15, and driver output #8 is used as a digital control signal for some other electronic circuits:
Note: The LED bar display modules with built-in voltage-controlled driver (like LM3914N) can not be used with digital outputs - you need to use PWM-controlled output for such displays instead.
