      • createShapes

        public Shape[] createShapes​(int count)
        Since we only have 4 shapes, the method will start with the first shape and keep cycling through the shapes in order.
        Parameters:
        count - The number of shapes to be created
        Returns:
        the first n shapes
      • nextShape

        public Shape nextShape()
        Return the next shape
        Returns:
        the next shape
      • createStrokes

        public Stroke[] createStrokes​(int count)
        Create a given number of Strokes
        Parameters:
        count - The number of strokes to be created
        Returns:
        the first count strokes
      • nextStroke

        public Stroke nextStroke()
        method always return a new BasicStroke with 1.0f weight
        Returns:
        a new BasicStroke with 1.0f weight
      • createPaint

        public Paint[] createPaint​(int count)
        return an array of Paint with different colors. The current implementation will cycle through 12 colors if a line graph has more than 12 entries
        Parameters:
        count - The number of Paints to be created
        Returns:
        an array of Paint with different colors
      • nextPaint

        public Paint nextPaint()
        The method will return the next paint color in the PAINT_ARRAY. Rather than return a random color, we want it to always go through the same sequence. This way, the same charts will always use the same color and make it easier to compare side by side.
        Returns:
        the next paint color in the PAINT_ARRAY
