Interface CategoryItemRenderer

    • Method Detail

      • getPassCount

        int getPassCount()
        Returns the number of passes through the dataset required by the renderer. Usually this will be one, but some renderers may use a second or third pass to overlay items on top of things that were drawn in an earlier pass.
        Returns:
        The pass count.
      • getPlot

        CategoryPlot getPlot()
        Returns the plot that the renderer has been assigned to (where null indicates that the renderer is not currently assigned to a plot).
        Returns:
        The plot (possibly null).
        See Also:
        setPlot(CategoryPlot)
      • setPlot

        void setPlot​(CategoryPlot plot)
        Sets the plot that the renderer has been assigned to. This method is usually called by the CategoryPlot, in normal usage you shouldn't need to call this method directly.
        Parameters:
        plot - the plot (null not permitted).
        See Also:
        getPlot()
      • findRangeBounds

        Range findRangeBounds​(CategoryDataset dataset)
        Returns the range of values the renderer requires to display all the items from the specified dataset.
        Parameters:
        dataset - the dataset (null permitted).
        Returns:
        The range (or null if the dataset is null or empty).
      • initialise

        CategoryItemRendererState initialise​(Graphics2D g2,
                                             Rectangle2D dataArea,
                                             CategoryPlot plot,
                                             int rendererIndex,
                                             PlotRenderingInfo info)
        Initialises the renderer. This method will be called before the first item is rendered, giving the renderer an opportunity to initialise any state information it wants to maintain. The renderer can do nothing if it chooses.
        Parameters:
        g2 - the graphics device.
        dataArea - the area inside the axes.
        plot - the plot.
        rendererIndex - the renderer index.
        info - collects chart rendering information for return to caller.
        Returns:
        A state object (maintains state information relevant to one chart drawing).
      • getItemVisible

        boolean getItemVisible​(int series,
                               int item)
        Returns a boolean that indicates whether or not the specified item should be drawn (this is typically used to hide an entire series).
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        A boolean.

        series - the series index.
        Returns:
        A boolean.
      • getSeriesVisible

        Boolean getSeriesVisible()
        Deprecated.
        This method should no longer be used (as of version 1.0.6). It is sufficient to rely on getSeriesVisible(int) and getBaseSeriesVisible().
