[y4233640]

chart.fitScreen();
This func can reset zoom.
/**
* Resets all zooming and dragging and makes the chart fit exactly it's
* bounds.
*/
public void fitScreen() {
Matrix save = mFitScreenMatrixBuffer;
mViewPortHandler.fitScreen(save);
mViewPortHandler.refresh(save, this, false);

    calculateOffsets();
    postInvalidate();
}
