public LineDataSet(java.util.List<Entry> yVals,
                   java.lang.String label)

Method Detail

copy

public DataSet<Entry> copy()

Description copied from class: DataSet

Provides an exact copy of the DataSet this method is used on.

Specified by:

copy in class DataSet<Entry>

Returns:

setCubicIntensity

public void setCubicIntensity(float intensity)

Sets the intensity for cubic lines (if enabled). Max = 1f = very cubic, Min = 0.05f = low cubic effect, Default: 0.2f

Parameters:

intensity -

getCubicIntensity

public float getCubicIntensity()

Returns the intensity of the cubic lines (the effect intensity).

Returns:

setCircleSize

public void setCircleSize(float size)

sets the size (radius) of the circle shpaed value indicators, default size = 4f

Parameters:

size -

getCircleSize

public float getCircleSize()

returns the circlesize

enableDashedLine

public void enableDashedLine(float lineLength,
                             float spaceLength,
                             float phase)

Enables the line to be drawn in dashed mode, e.g. like this "- - - - - -". THIS ONLY WORKS IF HARDWARE-ACCELERATION IS TURNED OFF. Keep in mind that hardware acceleration boosts performance.

Parameters:

lineLength - the length of the line pieces

spaceLength - the length of space in between the pieces

phase - offset, in degrees (normally, use 0)

disableDashedLine

public void disableDashedLine()

Disables the line to be drawn in dashed mode.

isDashedLineEnabled

public boolean isDashedLineEnabled()

Returns true if the dashed-line effect is enabled, false if not.

Returns:

getDashPathEffect

public android.graphics.DashPathEffect getDashPathEffect()

returns the DashPathEffect that is set for this DataSet

Returns:

setDrawCircles

public void setDrawCircles(boolean enabled)

set this to true to enable the drawing of circle indicators for this DataSet, default true

Parameters:

enabled -

isDrawCirclesEnabled

public boolean isDrawCirclesEnabled()

returns true if drawing circles for this DataSet is enabled, false if not

Returns:

setDrawCubic

public void setDrawCubic(boolean enabled)

If set to true, the linechart lines are drawn in cubic-style instead of linear. This affects performance! Default: false

Parameters:

enabled -

isDrawCubicEnabled

public boolean isDrawCubicEnabled()

returns true if drawing cubic lines is enabled, false if not.

Returns:

getCircleColors

public java.util.List<java.lang.Integer> getCircleColors()

returns all colors specified for the circles

Returns:

getCircleColor

public int getCircleColor(int index)

Returns the color at the given index of the DataSet's circle-color array. Performs a IndexOutOfBounds check by modulus.

Parameters:

index -

Returns:

setCircleColors

public void setCircleColors(java.util.List<java.lang.Integer> colors)

Sets the colors that should be used for the circles of this DataSet. Colors are reused as soon as the number of Entries the DataSet represents is higher than the size of the colors array. Make sure that the colors are already prepared (by calling getResources().getColor(...)) before adding them to the DataSet.

Parameters:

colors -

setCircleColors

public void setCircleColors(int[] colors)

Sets the colors that should be used for the circles of this DataSet. Colors are reused as soon as the number of Entries the DataSet represents is higher than the size of the colors array. Make sure that the colors are already prepared (by calling getResources().getColor(...)) before adding them to the DataSet.

Parameters:

colors -

setCircleColors

public void setCircleColors(int[] colors,
                            android.content.Context c)

ets the colors that should be used for the circles of this DataSet. Colors are reused as soon as the number of Entries the DataSet represents is higher than the size of the colors array. You can use "new String[] { R.color.red, R.color.green, ... }" to provide colors for this method. Internally, the colors are resolved using getResources().getColor(...)

Parameters:

colors -

setCircleColor

public void setCircleColor(int color)

Sets the one and ONLY color that should be used for this DataSet. Internally, this recreates the colors array and adds the specified color.

Parameters:

color -

resetCircleColors

public void resetCircleColors()

resets the circle-colors array and creates a new one

setCircleColorHole

public void setCircleColorHole(int color)

Sets the color of the inner circle of the line-circles.

Parameters:

color -

getCircleHoleColor

public int getCircleHoleColor()

Returns the color of the inner circle.

Returns:

setDrawCircleHole

public void setDrawCircleHole(boolean enabled)

Set this to true to allow drawing a hole in each data circle.

Parameters:

enabled -

isDrawCircleHoleEnabled

public boolean isDrawCircleHoleEnabled()

setFillFormatter

public void setFillFormatter(FillFormatter formatter)

Sets a custom FillFormatter to the chart that handles the position of the filled-line for each DataSet. Set this to null to use the default logic.

Parameters:

formatter -

getFillFormatter

public FillFormatter getFillFormatter()

Returns the FillFormatter that is set for this DataSet.

Returns:
