    • getFontHeight

      int getFontHeight()
      Returns:
      The height of the font that the renderer is going to use when painting the ordinate-label.

      Parameters:
      aMinOrdinateAlt - the value indicated by the lowest grid line
      aMaxOrdinateAlt - the value indicated by the highest grid line
      aGraphics - the Graphics the grid will be paint on
      Returns:
      The width in pixels that will be preserved for the ordinate label.
