getCircleHoleRadius

public float getCircleHoleRadius()

Description copied from interface: ILineDataSet

Returns the hole radius of the drawn circles.

Specified by:

getCircleHoleRadius in interface ILineDataSet

setCircleSize

@Deprecated
public void setCircleSize(float size)

Deprecated.

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

This method is deprecated because of unclarity. Use setCircleRadius instead.

Parameters:

size -

getCircleSize

@Deprecated
public float getCircleSize()

Deprecated.

This function is deprecated because of unclarity. Use getCircleRadius instead.

enableDashedLine

public void enableDashedLine(float lineLength,

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

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.
