Modifier and Type	Method and Description
static BufferedImage	draw(Number[] xValues, Number[] yValues, Number yMinValue, Number yMaxValue, SparklineParameters parameters) Draw a sparkline with x axis and y axis values, and pre-calculated min and max of the y axis values.
static BufferedImage	draw(Number[] xValues, Number[] yValues, SparklineParameters parameters) Draw a sparkline with x axis and y axis values.
static BufferedImage	draw(Number[] yValues, Number yMinValue, Number yMaxValue, SparklineParameters parameters) Draw a sparkline only providing y axis values, and pre-calculated min and max of the y axis values.
static BufferedImage	draw(Number[] values, SparklineParameters parameters) Draw a sparkline only providing y axis values (1 x tick per number assumed)

Method Detail

draw

public static BufferedImage draw(Number[] values,
                                 SparklineParameters parameters)

Draw a sparkline only providing y axis values (1 x tick per number assumed)

Parameters:

values - Y axis values

parameters - Rendering parameters

Returns:

Image of the sparkline

draw

public static BufferedImage draw(Number[] xValues,
                                 Number[] yValues,
                                 SparklineParameters parameters)

Draw a sparkline with x axis and y axis values. X values must be ordered and not repeated.

Parameters:

xValues - X axis values

yValues - Y axis values

parameters - Rendering parameters

Returns:

Image of the sparkline

draw

public static BufferedImage draw(Number[] yValues,
                                 Number yMinValue,
                                 Number yMaxValue,
                                 SparklineParameters parameters)

Draw a sparkline only providing y axis values, and pre-calculated min and max of the y axis values. Use this when you already have min/max values calculated and want to avoid extra calculations by SparklineGraph

Parameters:

yValues - Y axis values

yMinValue - Minimum value of the Y axis, should be correct

yMaxValue - Maximum value of the Y axis, should be correct

parameters - Rendering parameters

Returns:

Image of the sparkline

draw

public static BufferedImage draw(Number[] xValues,
                                 Number[] yValues,
                                 Number yMinValue,
                                 Number yMaxValue,
                                 SparklineParameters parameters)

Draw a sparkline with x axis and y axis values, and pre-calculated min and max of the y axis values. Use this when you already have min/max values calculated and want to avoid extra calculations by SparklineGraph X values must be ordered and not repeated.

Parameters:

xValues - X axis values

yValues - Y axis values

yMinValue - Minimum value of the Y axis, should be correct

yMaxValue - Maximum value of the Y axis, should be correct

parameters - Rendering parameters

Returns:

Image of the sparkline
