Member Function Documentation

dDefine()

void Gauge::dDefine	(	uint16_t	x0,
		uint16_t	y0,
		uint16_t	dx,
		uint16_t	dy,
		int32_t	valueMin,
		int32_t	valueMax,
		int32_t	unit = 1,
		uint16_t	grid = 8,
		uint16_t	valueColour = myColours.black )

Define the graphic, vector coordinates.

Parameters

screen	&screen to which the graphic belongs
x0	point coordinate, x-axis
y0	point coordinate, y-axis
dx	length, x-axis
dy	height, y-axis
valueMin	minimum value for measures, already multiplied by unit
valueMax	maximum value for measures, already multiplied by unit
unit	multiplier for all values, default = 1, 10 or 100
grid	number of areas for measures, default = 8, 0 = no grid
valueColour	16-bit colour for measures, default = black, optional

More: Coordinates, Colours, Value

define()

void Gauge::define	(	uint16_t	x0,
		uint16_t	y0,
		uint16_t	radius,
		int32_t	valueMin,
		int32_t	valueMax,
		int32_t	unit = 1,
		uint16_t	grid = 8,
		uint16_t	valueColour = myColours.black )

Define the graphic, rectangle coordinates.

Parameters

screen	&screen to which the graphic belongs
x0	center, point coordinate, x-axis
y0	center, point coordinate, y-axis
radius	radius
valueMin	minimum value for measures
valueMax	maximum value for measures, already multiplied by unit
unit	multiplier for all values, default = 1, 10 or 100
grid	number of areas for measures, default = 8, 0 = no grid
valueColour	16-bit colour for measures, default = black, optional

More: Coordinates, Colours, Value

draw()

void Gauge::draw	(	int32_t	value,
		STRING_CONST_TYPE	text = "" )

Update the graphic.

Parameters

value	new measure, already multiplied by unit
stringValue	label, default = "", optional

Note

If value=1234 with unit=100, actual value is 1234/100=12.34

More: Value
