Method Summary

Modifier and Type	Method and Description
void	appendData(E dataPoint, boolean scrollToEnd, int maxDataPoints, boolean silent)
void	draw(GraphView graphView, Canvas canvas, boolean isSecondScale) plots the series draws the line and the background
void	drawSelection(GraphView graphView, Canvas canvas, boolean b, DataPointInterface value)
int	getBackgroundColor()
float	getDataPointsRadius()
int	getThickness() the thickness of the line.
protected void	init() do the initialization creates internal objects
boolean	isDrawAsPath() flag whether the line should be drawn as a path or with single drawLine commands (more performance) By default we use drawLine because it has much more peformance.
boolean	isDrawBackground() flag whether the area under the line to the bottom of the viewport will be filled with a specific background color.
boolean	isDrawDataPoints() flag whether the data points are highlighted as a visible point.
void	setAnimated(boolean animated)
void	setBackgroundColor(int backgroundColor)
void	setCustomPaint(Paint customPaint) custom paint that can be used.
void	setDataPointsRadius(float dataPointsRadius)
void	setDrawAsPath(boolean mDrawAsPath) flag whether the line should be drawn as a path or with single drawLine commands (more performance) By default we use drawLine because it has much more peformance.
void	setDrawBackground(boolean drawBackground) flag whether the area under the line to the bottom of the viewport will be filled with a specific background color.
void	setDrawDataPoints(boolean drawDataPoints) flag whether the data points are highlighted as a visible point.
void	setThickness(int thickness) the thickness of the line.

Constructor Detail

LineGraphSeries

public LineGraphSeries()

creates a series without data

LineGraphSeries

public LineGraphSeries(E[] data)

creates a series with data

Parameters:

data - data points important: array has to be sorted from lowest x-value to the highest

Method Detail

init

protected void init()

do the initialization creates internal objects

draw

public void draw(GraphView graphView,
                 Canvas canvas,
                 boolean isSecondScale)

plots the series draws the line and the background

Parameters:

graphView - graphview

canvas - canvas

isSecondScale - flag if it is the second scale

getThickness

public int getThickness()

the thickness of the line. This option will be ignored if you are using a custom paint via #setCustomPaint(android.graphics.Paint)

Returns:

the thickness of the line

setThickness

public void setThickness(int thickness)

the thickness of the line. This option will be ignored if you are using a custom paint via #setCustomPaint(android.graphics.Paint)

Parameters:

thickness - thickness of the line

isDrawBackground

public boolean isDrawBackground()

flag whether the area under the line to the bottom of the viewport will be filled with a specific background color.

Returns:

whether the background will be drawn

See Also:

getBackgroundColor()

setDrawBackground

public void setDrawBackground(boolean drawBackground)

flag whether the area under the line to the bottom of the viewport will be filled with a specific background color.

Parameters:

drawBackground - whether the background will be drawn

See Also:

setBackgroundColor(int)

isDrawDataPoints

public boolean isDrawDataPoints()

flag whether the data points are highlighted as a visible point.

Returns:

flag whether the data points are highlighted

See Also:

setDataPointsRadius(float)

setDrawDataPoints

public void setDrawDataPoints(boolean drawDataPoints)

flag whether the data points are highlighted as a visible point.

Parameters:

drawDataPoints - flag whether the data points are highlighted

See Also:

setDataPointsRadius(float)

getDataPointsRadius

public float getDataPointsRadius()

Returns:

the radius for the data points.

See Also:

setDrawDataPoints(boolean)

setDataPointsRadius

public void setDataPointsRadius(float dataPointsRadius)

Parameters:

dataPointsRadius - the radius for the data points.

See Also:

setDrawDataPoints(boolean)

getBackgroundColor

public int getBackgroundColor()

Returns:

the background color for the filling under the line.

See Also:

setDrawBackground(boolean)

setBackgroundColor

public void setBackgroundColor(int backgroundColor)

Parameters:

backgroundColor - the background color for the filling under the line.

See Also:

setDrawBackground(boolean)

setCustomPaint

public void setCustomPaint(Paint customPaint)

custom paint that can be used. this will ignore the thickness and color styles.

Parameters:

customPaint - the custom paint to be used for rendering the line

setAnimated

public void setAnimated(boolean animated)

Parameters:

animated - activate the animated rendering

isDrawAsPath

public boolean isDrawAsPath()

flag whether the line should be drawn as a path or with single drawLine commands (more performance) By default we use drawLine because it has much more peformance. For some styling reasons it can make sense to draw as path.

setDrawAsPath

public void setDrawAsPath(boolean mDrawAsPath)

flag whether the line should be drawn as a path or with single drawLine commands (more performance) By default we use drawLine because it has much more peformance. For some styling reasons it can make sense to draw as path.

Parameters:

mDrawAsPath - true to draw as path

appendData

public void appendData(E dataPoint,
                       boolean scrollToEnd,
                       int maxDataPoints,
                       boolean silent)

Overrides:

appendData in class BaseSeries<E extends DataPointInterface>

Parameters:

dataPoint - values the values must be in the correct order! x-value has to be ASC. First the lowest x value and at least the highest x value.

scrollToEnd - true => graphview will scroll to the end (maxX)

maxDataPoints - if max data count is reached, the oldest data value will be lost to avoid memory leaks

silent - set true to avoid rerender the graph

drawSelection

public void drawSelection(GraphView graphView,
                          Canvas canvas,
                          boolean b,
                          DataPointInterface value)

Specified by:

drawSelection in class BaseSeries<E extends DataPointInterface>
