## BarGraph **Kind**: global class * [BarGraph](#BarGraph) * [new BarGraph(displayOTron)](#new_BarGraph_new) * [.turnOff()](#BarGraph+turnOff) * [.setByPercentage(percentage)](#BarGraph+setByPercentage) * [.setBrightnessOfLed(ledIndex, brightness)](#BarGraph+setBrightnessOfLed) ### new BarGraph(displayOTron) Creates a new `BarGraph` object. Note: you should not instantiate this class directly. Instead, use the `barGraph` property of an initialized `DOT3k` object. | Param | Type | Description | | --- | --- | --- | | displayOTron | DisplayOTron | The `DisplayOTron` instance. | ### barGraph.turnOff() Turns off the bar graph. **Kind**: instance method of [BarGraph](#BarGraph) ### barGraph.setByPercentage(percentage) Sets the bar graph by a percentage. **Kind**: instance method of [BarGraph](#BarGraph) | Param | Type | Description | | --- | --- | --- | | percentage | Number | The percentage (should be between 0 and 100). | ### barGraph.setBrightnessOfLed(ledIndex, brightness) Sets the brightness of a specific LED. **Kind**: instance method of [BarGraph](#BarGraph) | Param | Type | Description | | --- | --- | --- | | ledIndex | Number | The index of the LED (should be between 0 and 8). | | brightness | Number | The brightness value (should be between 0 and 255). |
