Setting the Titles of Charts or Axes

You can use Microsoft Excel to set the titles of a chart and its axes in a WYSIWYG environment. Aspose.Cells also allows developers to set the titles of a chart and its axes at runtime. All charts and their axes contain a Title object that can be used to set their titles as shown below in an example.

The following code snippet demonstrates how to set titles to charts and axes.

// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Adding a new worksheet to the Workbook object
int sheetIndex = workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.getWorksheets().get(sheetIndex);
// Adding sample values to cells
worksheet.getCells().get("A1").putValue("Series1");
worksheet.getCells().get("A2").putValue(50);
worksheet.getCells().get("A3").putValue(100);
worksheet.getCells().get("A4").putValue(150);
worksheet.getCells().get("B1").putValue("Series2");
worksheet.getCells().get("B2").putValue(60);
worksheet.getCells().get("B3").putValue(32);
worksheet.getCells().get("B4").putValue(50);
// Adding a chart to the worksheet
int chartIndex = worksheet.getCharts().add(ChartType.COLUMN, 5, 0, 15, 5);
// Accessing the instance of the newly added chart
Chart chart = worksheet.getCharts().get(chartIndex);
// Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
chart.getNSeries().add("A1:B3", true);
// Setting the title of a chart
chart.getTitle().setText("Title");
// Setting the font color of the chart title to blue
chart.getTitle().getFont().setColor( Color.getBlue());
// Setting the title of category axis of the chart
chart.getCategoryAxis().getTitle().setText ("Category");
// Setting the title of value axis of the chart
chart.getValueAxis().getTitle().setText ( "Value");
// Save the file
workbook.save("chart_datalabels.xlsx");
