import com.aspose.cells.*;
Step 2: Initialize a Workbook object.
Workbook workbook = new Workbook();
Step 3: Add a worksheet to the workbook.
Worksheet worksheet = workbook.getWorksheets().get(0);
Step 4: Create a combined chart object.
int chartIndex = worksheet.getCharts().add(ChartType.LINE, 0, 0, 20, 10);
Chart chart = worksheet.getCharts().get(chartIndex);
Adding Data to the Chart
Now that we have created a combined chart, let’s add some data to it.
Step 5: Create a data series for the chart.
Cells cells = worksheet.getCells();
chart.getNSeries().add("A1:A5", true);
chart.getNSeries().add("B1:B5", true);
Step 6: Set the category data range for the chart.
chart.getNSeries().setCategoryData("C1:C5");
Customizing the Chart
You can customize the appearance and behavior of the combined chart to meet your specific requirements.
Step 7: Customize the chart title and axis labels.
chart.getTitle().setText("Combined Chart Example");
chart.getCategoryAxis().getTitle().setText("Categories");
chart.getValueAxis().getTitle().setText("Values");
- Step 8: Adjust the chart’s appearance.
chart.getLegend().setPosition(LegendPositionType.BOTTOM);
chart.getLegend().setOverlay(true);
Saving and Exporting the Chart
Once you’ve created and customized your combined chart, you can save it to an Excel file or export it to various formats.
Step 9: Save the workbook to an Excel file.
workbook.save("CombinedChart.xlsx");
Step 10: Export the chart to an image file.
chart.toImage("CombinedChart.png", ImageFormat.getPng());
