com.positive.charts.renderer.xy.XYItemRenderer.initialise()
Initialises the renderer then returns the number of 'passes' through the data that the renderer will require (usually just one). 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. @param g2 the graphics device. @param dataArea the area inside the axes. @param plot the plot. @param dataset the dataset. @param info an optional info collection object to return data back to the caller. @return The number of passes the renderer requires.

      renderer = this.getRenderer();
    }


    // assert renderer != null : "Renderer is null";


    final XYItemRendererState state = renderer.initialise(gc, dataArea,
        this, dataset, info);
    final int passCount = renderer.getPassCount();


    final SeriesRenderingOrder seriesOrder = this.getSeriesRenderingOrder();
    if (seriesOrder == SeriesRenderingOrder.REVERSE) {
