      Returns:
      A boolean.

    • setUseFillPaintForShapeOutline

      public void setUseFillPaintForShapeOutline​(boolean use)
      Sets the flag that controls whether the fill paint is used for shape outlines.
      Parameters:
      use - the flag.

    • isDrawShapes

      public boolean isDrawShapes()
      Returns true if a shape should be drawn to represent each data point, and false otherwise.
      Returns:
      A boolean flag.

    • setDrawShapes

      public void setDrawShapes​(boolean draw)
      Sets the flag that controls whether or not a shape should be drawn to represent each data point.
      Parameters:
      draw - the new value of the flag.

    • isDrawLines

      public boolean isDrawLines()
      Returns true if a line should be drawn from the previous to the current data point, and false otherwise.
      Returns:
      A boolean flag.

    • setDrawLines

      public void setDrawLines​(boolean draw)
      Sets the flag that controls whether or not lines are drawn between consecutive data points.
      Parameters:
      draw - the new value of the flag.

    • getItemShapeFilled

      public boolean getItemShapeFilled​(int series, int item)
      Returns the flag used to control whether or not the shape for an item is filled.

      Parameters:
      series - the series index (zero-based).
      Returns:
      A boolean.

    • getShapesFilled
