Define XY Axis Properties In A Chart
This tutorial explains how to use Aspose.Words for .NET to define properties for the X and Y axes in a chart. The provided source code demonstrates how to create a chart, add series data, and customize the axis properties.
Step 1: Set up the project
Ensure that you have the following prerequisites:
- Aspose.Words for .NET library installed. You can download it by using NuGet package manager to install it.
- A document directory path where the output document will be saved.
Step 2: Create a new document and insert a chart
Create a new Document
object and a DocumentBuilder
to build the document.
// Path to your document directory
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Next, insert a chart into the document using the InsertChart
method of the DocumentBuilder
. In this example, we’ll insert an area chart.
Shape shape = builder.InsertChart(ChartType.Area, 432, 252);
Chart chart = shape.Chart;
Step 3: Add series data to the chart
Add series data to the chart. In this example, we’ll add five data points with corresponding dates and values.
chart.Series.Clear();
chart.Series.Add("Aspose Series 1",
new DateTime[]
{
new DateTime(2002, 01, 01), new DateTime(2002, 06, 01), new DateTime(2002, 07, 01),
new DateTime(2002, 08, 01), new DateTime(2002, 09, 01)
},
new double[] { 640, 320, 280, 120, 150 });
Step 4: Customize X and Y axis properties
To customize the properties of the X and Y axes, access the ChartAxis
objects associated with the chart.
ChartAxis xAxis = chart.AxisX;
ChartAxis yAxis = chart.AxisY;
Modify the properties of the xAxis
and yAxis
objects to set the desired options for the X and Y axes. In this example, we’ll demonstrate some common properties that can be customized.
xAxis.CategoryType = AxisCategoryType.Category;
xAxis.Crosses = AxisCrosses.Custom;
xAxis.CrossesAt = 3;
xAxis.ReverseOrder = true;
xAxis.MajorTickMark = AxisTickMark.Cross;
xAxis.MinorTickMark = AxisTickMark.Outside;
xAxis.TickLabelOffset = 200;
yAxis.TickLabelPosition = AxisTickLabelPosition.High;
yAxis.MajorUnit = 100;
yAxis.MinorUnit = 50;
yAxis.DisplayUnit.Unit = AxisBuiltInUnit.Hundreds;
yAxis.Scaling.Minimum = new AxisBound(100);
yAxis.Scaling.Maximum = new AxisBound(700);
Step 5: Save the document
Finally, save the document to the specified directory using the Save
method of the Document
object.
doc.Save(dataDir + "WorkingWithCharts.DefineXYAxisProperties.docx");
This completes the implementation of defining XY axis properties in a chart using Aspose.Words for .NET.
Example source code for Define XYAxis Properties using Aspose.Words for .NET
// Path to your document directory
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert chart
Shape shape = builder.InsertChart(ChartType.Area, 432, 252);
Chart chart = shape.Chart;
chart.Series.Clear();
chart.Series.Add("Aspose Series 1",
new DateTime[]
{
new DateTime(2002, 01, 01), new DateTime(2002, 06, 01), new DateTime(2002, 07, 01),
new DateTime(2002, 08, 01), new DateTime(2002, 09, 01)
},
new double[] { 640, 320, 280, 120, 150 });
ChartAxis xAxis = chart.AxisX;
ChartAxis yAxis = chart.AxisY;
// Change the X axis to be category instead of date, so all the points will be put with equal interval on the X axis.
xAxis.CategoryType = AxisCategoryType.Category;
xAxis.Crosses = AxisCrosses.Custom;
xAxis.CrossesAt = 3; // Measured in display units of the Y axis (hundreds).
xAxis.ReverseOrder = true;
xAxis.MajorTickMark = AxisTickMark.Cross;
xAxis.MinorTickMark = AxisTickMark.Outside;
xAxis.TickLabelOffset = 200;
yAxis.TickLabelPosition = AxisTickLabelPosition.High;
yAxis.MajorUnit = 100;
yAxis.MinorUnit = 50;
yAxis.DisplayUnit.Unit = AxisBuiltInUnit.Hundreds;
yAxis.Scaling.Minimum = new AxisBound(100);
yAxis.Scaling.Maximum = new AxisBound(700);
doc.Save(dataDir + "WorkingWithCharts.DefineXYAxisProperties.docx");
Conclusion
In this tutorial, you have learned how to define properties for the X and Y axes in a chart using Aspose.Words for .NET. By following the step-by-step guide, you can create a chart, add series data, and customize the axis properties to meet your specific requirements. Aspose.Words for .NET provides a comprehensive API for Words Processing with charts in Word documents, allowing you to manipulate various aspects of the chart, including the axes.
By accessing the ChartAxis
objects associated with the chart, you can modify properties such as the category type, axis crosses, tick marks, label positions, scaling, and more. This flexibility enables you to tailor the appearance and behavior of the chart’s axes to effectively present your data.
By using Aspose.Words for .NET, you can seamlessly integrate chart creation and customization capabilities into your .NET applications and automate the generation of professional-looking documents with rich visualizations.
