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 property 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.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
System.IO.Directory.CreateDirectory(dataDir);
// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Adding a new worksheet to the Workbook object
int sheetIndex = workbook.Worksheets.Add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[sheetIndex];
// Adding sample values to cells
worksheet.Cells["A1"].PutValue(50);
worksheet.Cells["A2"].PutValue(100);
worksheet.Cells["A3"].PutValue(150);
worksheet.Cells["B1"].PutValue(60);
worksheet.Cells["B2"].PutValue(32);
worksheet.Cells["B3"].PutValue(50);
// Adding a chart to the worksheet
int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 5, 0, 15, 5);
// Accessing the instance of the newly added chart
Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];
// Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
chart.NSeries.Add("A1:B3", true);
// Setting the foreground color of the plot area
chart.PlotArea.Area.ForegroundColor = Color.Blue;
// Setting the foreground color of the chart area
chart.ChartArea.Area.ForegroundColor = Color.Yellow;
// Setting the foreground color of the 1st SeriesCollection area
chart.NSeries[0].Area.ForegroundColor = Color.Red;
// Setting the foreground color of the area of the 1st SeriesCollection point
chart.NSeries[0].Points[0].Area.ForegroundColor = Color.Cyan;
// Filling the area of the 2nd SeriesCollection with a gradient
chart.NSeries[1].Area.FillFormat.SetOneColorGradient(Color.Lime, 1, Aspose.Cells.Drawing.GradientStyleType.Horizontal, 1);
// Setting the title of a chart
chart.Title.Text = "Title";
// Setting the font color of the chart title to blue
chart.Title.Font.Color = Color.Blue;
// Setting the title of category axis of the chart
chart.CategoryAxis.Title.Text = "Category";
// Setting the title of value axis of the chart
chart.ValueAxis.Title.Text = "Value";
// Saving the Excel file
workbook.Save(dataDir + "book1.out.xls");
