title: Axes of GraphicalView of AchartEngine
body: <p>I have a graphicalview element which updates in realtime.
  I know from the beginning the interval in which my values will stay.
  Therefore I would like my Y axes to be set in a way that shows that entire interval from the beginning.
  At the momente the Y axes changes on the basis of the values that arrives. For example if my values' interval  is (0, 10) but I have received only points whos Y is equal to 3, the maximum values of the Y axes will be 3, instead I want it to be 10.</p>
  
  <p>Any suggestion?
  I know that I have to set some parameters of the XYMultipleSeriesRender but which one?</p>
