示例1: createCategoryDomainAxis
import org.jfree.chart.axis.CategoryAxis; //導入方法依賴的package包/類
public static CategoryAxis createCategoryDomainAxis(PlotConfiguration plotConfiguration) {
CategoryAxis domainAxis = new CategoryAxis(null);
String label = plotConfiguration.getDomainConfigManager().getLabel();
if (label == null) {
label = I18N.getGUILabel("plotter.unnamed_value_label");
}
domainAxis.setLabel(label);
Font axesFont = plotConfiguration.getAxesFont();
if (axesFont != null) {
domainAxis.setLabelFont(axesFont);
domainAxis.setTickLabelFont(axesFont);
}
// rotate labels
if (plotConfiguration.getOrientation() != PlotOrientation.HORIZONTAL) {
domainAxis.setCategoryLabelPositions(CategoryLabelPositions.createUpRotationLabelPositions(Math.PI / 2.0d));
}
formatAxis(plotConfiguration, domainAxis);

示例2: BarChart
import org.jfree.chart.axis.CategoryAxis; //導入方法依賴的package包/類
public BarChart() {
CategoryDataset dataset = getDataSet();
JFreeChart chart = ChartFactory.createBarChart3D(
"水果", // 圖表標題
"水果種類", // 目錄軸的顯示標簽
"數量", // 數值軸的顯示標簽
dataset, // 數據集
PlotOrientation.VERTICAL, // 圖表方向：水平、垂直
true, // 是否顯示圖例(對於簡單的柱狀圖必須是false)
false, // 是否生成工具
false // 是否生成URL鏈接
);
//從這裏開始
CategoryPlot plot = chart.getCategoryPlot();//獲取圖表區域對象
CategoryAxis domainAxis = plot.getDomainAxis(); //水平底部列表
domainAxis.setLabelFont(new Font("黑體", Font.BOLD, 14)); //水平底部標題
domainAxis.setTickLabelFont(new Font("宋體", Font.BOLD, 12)); //垂直標題
ValueAxis rangeAxis = plot.getRangeAxis();//獲取柱狀
rangeAxis.setLabelFont(new Font("黑體", Font.BOLD, 15));
chart.getLegend().setItemFont(new Font("黑體", Font.BOLD, 15));
chart.getTitle().setFont(new Font("宋體", Font.BOLD, 20));//設置標題字體
//到這裏結束，雖然代碼有點多，但隻為一個目的，解決漢字亂碼問題
frame1 = new ChartPanel(chart, true); //這裏也可以用chartFrame,可以直接生成一個獨立的Frame
