我已经在网上搜索了足够多的东西,但没有运气。
我创建了一个堆叠的 3d 条形图,其中我无法更改默认颜色。我尝试了提供的所有建议。
下面是我的代码的一小段。这是我的输入。
我来自 Db 的数据是:
一个 0 2 乙 15 53 0 2 0 2 0 1 F 1 0 G 0 1
不知何故,我将其转换为数据集要求,并添加了项目和模型。
CategoryDataset dataset = DatasetUtilities.createCategoryDataset(item,models, data);
chart = ChartFactory.createStackedBarChart3D(chartDescription, X-axis, Y-axis, dataset,PlotOrientation.VERTICAL, true, true, true);
CategoryPlot plot = chart.getCategoryPlot();
CategoryItemRenderer r = plot.getRenderer();
r.setSeriesPaint(0, Color.GREEN);
r.setSeriesPaint(1, Color.GRAY);
plot.setRenderer(new StackedBarRenderer3D() {
@Override
public Paint getItemPaint(int row, int col) {
System.out.println("row:"+row);
System.out.println("Col:"+col);
return Color.getHSBColor(row / 42f, 1, 1);
}
});
CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_90);
NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
StackedBarRenderer3D renderer = (StackedBarRenderer3D)plot.getRenderer();
//renderer.setBarPainter(new StandardBarPainter());
renderer.setSeriesFillPaint(0,Color.BLACK);
renderer.setSeriesFillPaint(1,Color.GREEN);
renderer.setDrawBarOutline(false);
renderer.setShadowVisible(false);
renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(ItemLabelAnchor.CENTER,TextAnchor.CENTER));
renderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
renderer.setIgnoreZeroValues(true);
renderer.setMaximumBarWidth(.05);
renderer.setBaseItemLabelsVisible(true);
renderer.setBaseToolTipGenerator(new StandardCategoryToolTipGenerator());
renderer.setPositiveItemLabelPositionFallback(new ItemLabelPosition(
ItemLabelAnchor.CENTER, TextAnchor.CENTER_RIGHT));
renderer.setNegativeItemLabelPositionFallback(new ItemLabelPosition(
ItemLabelAnchor.CENTER, TextAnchor.CENTER_RIGHT));
renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(
ItemLabelAnchor.CENTER, TextAnchor.TOP_CENTER));
renderer.setBaseNegativeItemLabelPosition(new ItemLabelPosition(
ItemLabelAnchor.CENTER, TextAnchor.TOP_CENTER));
LegendTitle legend = chart.getLegend(0);
legend.setBackgroundPaint(Color.white);
legend.setFrame(new BlockBorder(Color.green));
StandardChartTheme theme = (StandardChartTheme)org.jfree.chart.StandardChartTheme.createJFreeTheme();
theme.setTitlePaint(Color.decode("#4572a7"));
theme.setExtraLargeFont(new Font("Arial",Font.BOLD, 16) );
theme.setLargeFont(new Font("Arial",Font.BOLD, 15));
theme.setRegularFont( new Font("Arial",Font.PLAIN, 11));
theme.setRangeGridlinePaint(Color.RED);
theme.setPlotBackgroundPaint( Color.white );
theme.setChartBackgroundPaint( Color.white );
theme.setItemLabelPaint(Color.YELLOW);
theme.setShadowVisible(true);
theme.setAxisLabelPaint( Color.decode("#666666") );
theme.apply( chart );
即使我用过setSeriespaint
,但它不起作用。图表、绘图和渲染器中的创建顺序有什么关系吗?
当我打印行和列时,我得到了这个:
行:1 颜色:0 行:0 列:1 行:1 列:1 行:1 Col:2 行:1 Col:3 行:1 Col:4 行:0 彩色:5 行:1 列:6
