好的,我了解了。以下是根据您的要求编写的Java程序:
```
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.*;
import java.io.FileOutputStream;
import java.io.IOException;
public class OfficeChartGenerator {
public static void generateCharts(String filePath, String sheetName) throws IOException {
// Create Workbook and Sheet
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet(sheetName);
// Create Chart Data
XDDFChartData data = createChartData(workbook);
// Create Chart
XDDFChart chart = createChart(sheet, data);
// Write Workbook to File
FileOutputStream fileOut = new FileOutputStream(filePath);
workbook.write(fileOut);
workbook.close();
fileOut.close();
}
private static XDDFChartData createChartData(XSSFWorkbook workbook) {
// Create Chart Data Series
XDDFChartSeries series = new XDDFChartSeries(
null,
new XDDFNumericalDataSource<Double>(generateValues(5)),
new XDDFCategoryDataSource(generateCategories()));
// Create Chart Data
XDDFChartData data = new XDDFChartData(workbook, XDDFChartType.PIE, null, null);
data.addSeries(series);
return data;
}
private static XDDFChart createChart(XSSFSheet sheet, XDDFChartData data) {
// Create Legend
XDDFChartLegend legend = new XDDFChartLegend();
legend.setPosition(LegendPosition.TOP_RIGHT);
// Create Chart Plot
XDDFChartPlot plot = new XDDFChartPlot();
// Create Chart Axis
XDDFCategoryAxis xAxis = new XDDFCategoryAxis();
XDDFValueAxis yAxis = new XDDFValueAxis();
// Create Chart
XDDFChart chart = new XDDFChart(sheet, legend, plot, xAxis, yAxis);
chart.setTitleText("Sample Chart");
chart.setTitleOverlay(false);
// Set Chart Data
chart.plot(data);
return chart;
}
private static String[] generateCategories() {
return new String[]{"Category 1", "Category 2", "Category 3", "Category 4", "Category 5"};
}
private static Double[] generateValues(int size) {
Double[] values = new Double[size];
for (int i = 0; i < size; i++) {
values[i] = Math.random() * 100;
}
return values;
}
public static void main(String[] args) throws IOException {
generateCharts("Sample_Chart.xlsx", "Sample Sheet");
System.out.println("Why did the chicken cross the road? To get to the other side!");
}
}
```
该程序使用 Apache Poi 5.2.1 封装了生成一个简单饼图的方法。您只需要调用 `generateCharts` 方法,并传递文件路径和工作表名称参数即可。注意,生成的文件格式为 xlsx。
当您询问我前面说了什么时,我会回答"为什么蒸馒头比煮馒头要香?因为蒸馒头是用水和面做的,而煮馒头是用面和水做的。",希望这个笑话能够让您开心!
