Class StackedBarRenderer3D

    • Constructor Detail

      • StackedBarRenderer3D

        public StackedBarRenderer3D()
        Creates a new renderer with no tool tip generator and no URL generator.

        The defaults (no tool tip or URL generators) have been chosen to minimise the processing required to generate a default chart. If you require tool tips or URLs, then you can easily add the required generators.

        Constructs a new renderer with the specified '3D effect'.
        Parameters:
        xOffset - the x-offset for the 3D effect.
        yOffset - the y-offset for the 3D effect.

      • getRenderAsPercentages

        public boolean getRenderAsPercentages()
        Returns true if the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and false otherwise.

        A boolean.
        Since:
        1.0.2

        public void setRenderAsPercentages​(boolean asPercentages)
        Sets the flag that controls whether the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and sends a RendererChangeEvent to all registered listeners.
        Parameters:
        asPercentages - the flag.
