com.positive.charts.renderer.category.CategoryItemRenderer.initialise()

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. @param g2 the graphics device. @param dataArea the area inside the axes. @param plot the plot. @param rendererIndex the renderer index. @param info collects chart rendering information for return to caller. @return A state object (maintains state information relevant to one chartdrawing).

    final ValueAxis rangeAxis = this.getRangeAxisForDataset(index);
    final boolean hasData = !DatasetUtilities.isEmptyOrNull(currentDataset);
    if (hasData && (renderer != null)) {


      foundData = true;
      final CategoryItemRendererState state = renderer.initialise(g2,
          dataArea, this, index, info);
      final int columnCount = currentDataset.getColumnCount();
      final int rowCount = currentDataset.getRowCount();
      final int passCount = renderer.getPassCount();
      for (int pass = 0; pass < passCount; pass++) {
