Method Summary

Modifier and Type	Method and Description
void	draw(android.graphics.Canvas canvas, float posX, float posY) Draws the IMarker on the given position on the screen with the given Canvas object.
MPPointF	getOffset()
MPPointF	getOffsetForDrawingAtPoint(float posX, float posY)
void	refreshContent(Entry e, Highlight highlight) This method enables a specified custom IMarker to update it's content every time the IMarker is redrawn.

Method Detail

getOffset

MPPointF getOffset()

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.

getOffsetForDrawingAtPoint

MPPointF getOffsetForDrawingAtPoint(float posX,
                                    float posY)

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

void refreshContent(Entry e,
                    Highlight highlight)

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

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).

          float posX,
          float posY)
