Constructor Detail

MarkerImage

public MarkerImage(android.content.Context context,
                   int drawableResourceId)

Constructor. Sets up the MarkerView with a custom layout resource.

Parameters:

context -

drawableResourceId - the drawable resource to render

Method Detail

setOffset

public void setOffset(MPPointF offset)

setOffset

public void setOffset(float offsetX,
                      float offsetY)

getOffset

public MPPointF getOffset()

Specified by:

getOffset in interface IMarker

Returns:

The desired (general) offset you wish the IMarker to have on the x- and y-axis. By returning x: -(width / 2) you will center the IMarker horizontally. By returning y: -(height / 2) you will center the IMarker vertically.

setSize

public void setSize(FSize size)

getSize

public FSize getSize()

setChartView

public void setChartView(Chart chart)

getChartView

public Chart getChartView()

getOffsetForDrawingAtPoint

public MPPointF getOffsetForDrawingAtPoint(float posX,
                                           float posY)

Specified by:

getOffsetForDrawingAtPoint in interface IMarker

Parameters:

posX - This is the X position at which the marker wants to be drawn. You can adjust the offset conditionally based on this argument.

posY - This is the X position at which the marker wants to be drawn. You can adjust the offset conditionally based on this argument.

Returns:

The offset for drawing at the specific `point`. This allows conditional adjusting of the Marker position. If you have no adjustments to make, return getOffset().

refreshContent

public void refreshContent(Entry e,
                           Highlight highlight)

Description copied from interface: IMarker

This method enables a specified custom IMarker to update it's content every time the IMarker is redrawn.

Specified by:

refreshContent in interface IMarker

Parameters:

e - The Entry the IMarker belongs to. This can also be any subclass of Entry, like BarEntry or CandleEntry, simply cast it at runtime.

highlight - The highlight object contains information about the highlighted value such as it's dataset-index, the selected range or stack-index (only stacked bar entries).

draw

public void draw(android.graphics.Canvas canvas,
                 float posX,
                 float posY)

Description copied from interface: IMarker

Draws the IMarker on the given position on the screen with the given Canvas object.

Specified by:
