		+
		+	The flashlight tag defines the phone's flashlight (usually part of the camera group) as an output. If frequency and dutycycle are not set, you can simply control the brightness of the flashlight (including turning it off) via the '''intensity''' input. If '''frequency''' is set to a value above 0, the flashlight acts as a stroboscope with the given frequency. You can also change the duty cycle through the '''dutycycle''' input.
		+
		+	Note, that most phones cannot switch the flash state faster than 25ms. High frequencies or duty cycles far from 0.5 will require faster changes and may not be reproduced correctly by the phone. Phyphox cannot measure how fast the flashlight reacts and the reaction time may even vary from switch event to switch event. So be careful to verify if it is working correctly if fast switches are required.
		+
		+	'''input (intensity)'''
		+	The '''intensity''' input controls the brightness of the flashlight. It can be set from 0 (off) to 1 (max brightness). The number of supported brightness levels varies from phone to phone and older models might only support an on and off state. (Default: 1 / max brightness)
		+
		+	'''input (frequency)'''
		+	The frequency of the strobe output. If this is set to zero, the flashlight will be on constantly. (Default: 0)
		+
		+	'''input (dutycycle)'''
		+	The duty cycle of the strobe output. This is given in the range from 0 (always off) to 1 (always on). The default is 0.5 (equal on/off durations). (Default: 0.5)

 : '''Deprecation warning''': This feature has been marked as depricated and will be removed soon. Please implement it in phyphox analysis logic by using additional data-containers and copying the shown graph into these on each update. This has several advantages like being able to export the history data and better control over its style. Original description: The number of graphs to be shown. 1 means, that the current data is shown. n means, that n graphs are shown, with n-1 graphs containing the data from the previous update. This attribute only makes sense, when the whole graph is replaced on each analysis cycle and can be used to compare the previous n results within a single graph. '''Deprecated since phyphox file format 1.15 (phyphox 1.1.12))'''
