Darstellung des Diagramms einstellen

In So erstellen Sie ein Diagramm haben wir eine kurze Einführung in die Arten von Diagrammen und Diagrammobjekten gegeben, die von Aspose.Cells angeboten werden, und beschrieben, wie Sie eines erstellen. In diesem Artikel wird erläutert, wie Sie das Erscheinungsbild von Diagrammen anpassen, indem Sie ihre Eigenschaften festlegen:

• Einstellen des Diagrammbereichs.
• Diagrammlinien setzen.
• Themen anwenden.
• Titel für Diagramme und Achsen festlegen.
• Arbeiten mit Gitterlinien.

Diagrammbereich einstellen

Es gibt verschiedene Arten von Bereichen in einem Diagramm und Aspose.Cells bietet die Flexibilität, das Erscheinungsbild jedes Bereichs zu ändern. Entwickler können verschiedene Formatierungseinstellungen auf einen Bereich anwenden, indem sie dessen Vordergrundfarbe, Hintergrundfarbe und Füllformat usw. ändern.

In dem unten angegebenen Beispiel haben wir verschiedene Formatierungseinstellungen auf verschiedene Arten von Bereichen eines Diagramms angewendet. Zu diesen Bereichen gehören:

• Grundstücksfläche
• Diagrammbereich
• SeriesCollection-Bereich
• Bereich eines einzelnen Punkts in einer SeriesCollection

Das folgende Code-Snippet zeigt, wie Sie den Diagrammbereich festlegen.

// 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);

// Saving the Excel file
workbook.Save(dataDir + "book1.out.xls");

Diagrammlinien festlegen

Entwickler können auch verschiedene Arten von Stilen auf die Linien oder Datenmarkierungen des anwendenSerieSammlung. Das folgende Code-Snippet zeigt, wie Sie Diagrammlinien mit Aspose.Cells API festlegen.

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);

// 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);

// Applying a dotted line style on the lines of a SeriesCollection
chart.NSeries[0].Border.Style = Aspose.Cells.Drawing.LineType.Dot;

// Applying a triangular marker style on the data markers of a SeriesCollection
chart.NSeries[0].Marker.MarkerStyle = Aspose.Cells.Charts.ChartMarkerType.Triangle;

// Setting the weight of all lines in a SeriesCollection to medium
chart.NSeries[1].Border.Weight = Aspose.Cells.Drawing.WeightType.MediumLine;


// Saving the Excel file
workbook.Save(dataDir + "book1.out.xls");

Anwenden von Microsoft Excel 2007/2010-Designs auf Diagramme

Entwickler können verschiedene Microsoft Excel-Designs/-Farben anwendenSerieSammlungoder andere Diagrammobjekte, wie unten im Beispiel gezeigt.

// 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);

// Instantiate the workbook to open the file that contains a chart
Workbook workbook = new Workbook(dataDir + "book1.xlsx");

// Get the first worksheet
Worksheet worksheet = workbook.Worksheets[1];

// Get the first chart in the sheet
Chart chart = worksheet.Charts[0];

// Specify the FilFormat's type to Solid Fill of the first series
chart.NSeries[0].Area.FillFormat.FillType = Aspose.Cells.Drawing.FillType.Solid;

// Get the CellsColor of SolidFill
CellsColor cc = chart.NSeries[0].Area.FillFormat.SolidFill.CellsColor;

// Create a theme in Accent style
cc.ThemeColor = new ThemeColor(ThemeColorType.Accent6, 0.6);

// Apply the them to the series
chart.NSeries[0].Area.FillFormat.SolidFill.CellsColor = cc;

// Save the Excel file
workbook.Save(dataDir + "output.out.xlsx");

Festlegen der Titel von Diagrammen oder Achsen

Sie können Microsoft Excel verwenden, um die Titel eines Diagramms und seine Achsen in einer WYSIWYG-Umgebung festzulegen. Aspose.Cells ermöglicht es Entwicklern auch, die Titel eines Diagramms und seiner Achsen zur Laufzeit festzulegen. Alle Diagramme und ihre Achsen enthalten aTitelEigenschaft, die verwendet werden kann, um ihre Titel festzulegen, wie unten in einem Beispiel gezeigt.

Das folgende Code-Snippet zeigt, wie Titel für Diagramme und Achsen festgelegt werden.
