Chart

Examples for adding, accessing, removing, and updating different chart types with Aspose.Slides for .NET. The snippets below demonstrate basic chart operations.

Download and run

Download the complete project, extract it, and open Example.sln or run:

dotnet restore Example.sln
dotnet run --project Example.csproj -- --mode evaluation

The download includes every case below, its fixture helpers and inputs. Program.cs runs all cases; use --action block-001 to run one independently. Outputs and an action report are written to the printed output directory. No previous example or working-directory setup is required. Evaluation adds a watermark and can truncate read-back text; the short fixtures still have explicit structural checks. For full text and no watermark, use --mode licensed --license PATH with your own valid license. See the setup guide for supported SDKs and native prerequisites.

Each printed CaseNN.cs file is compiled verbatim with the included Program.cs and bootstrap. Checks run before saving and after reopening the result.

Add a Chart

This method adds a simple area chart to the first slide.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.Charts;

internal static partial class Program
{
    static void Case01()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        // Add a simple area chart to the first slide.
        var chart = slide.Shapes.AddChart(ChartType.Area, 50, 50, 400, 300);

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-001", p =>
        {
            Context.Require(p.Slides[0].Shapes.OfType<IChart>().Single().Type == ChartType.Area, "AddChart: semantic check 1 failed.");
        });
        Context.Pass("elements/chart/block-001", "AddChart", "save-reopen-structure");
    }
}

Access a Chart

After creating a chart, you can retrieve it through the shape collection.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.Charts;

internal static partial class Program
{
    static void Case02()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        var chart = slide.Shapes.AddChart(ChartType.Line, 50, 50, 400, 300);

        // Access the first chart on the slide.
        var firstChart = slide.Shapes.OfType<IChart>().First();

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-002", p =>
        {
            Context.Require(p.Slides[0].Shapes.OfType<IChart>().Single().Type == ChartType.Line, "AccessChart: semantic check 1 failed.");
        });
        Context.Pass("elements/chart/block-002", "AccessChart", "save-reopen-structure");
    }
}

Remove a Chart

The following code removes a chart from a slide.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.Charts;

internal static partial class Program
{
    static void Case03()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];

        var chart = slide.Shapes.AddChart(ChartType.Pie, 50, 50, 400, 300);

        // Remove the chart.
        slide.Shapes.Remove(chart);

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-003", p =>
        {
            Context.Require(!p.Slides[0].Shapes.OfType<IChart>().Any(), "RemoveChart: semantic check 1 failed.");
        });
        Context.Pass("elements/chart/block-003", "RemoveChart", "save-reopen-structure");
    }
}

Update Chart Data

You can change chart properties such as the title.

using System;
using System.IO;
using System.Linq;
using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.Charts;

internal static partial class Program
{
    static void Case04()
    {
        using var presentation = new Presentation();
        var slide = presentation.Slides[0];
        
        var chart = slide.Shapes.AddChart(ChartType.Column3D, 50, 50, 400, 300);

        chart.HasTitle = true;

        // Change the chart title.
        chart.ChartTitle.AddTextFrameForOverriding("Sales");

        // Validate the in-memory operation and its persisted result independently.
        RoundTrip(presentation, "block-004", p =>
        {
            Context.Require(p.Slides[0].Shapes.OfType<IChart>().Single().ChartTitle.TextFrameForOverriding.Text == "Sales", "UpdateChartData: semantic check 1 failed.");
        });
        Context.Pass("elements/chart/block-004", "UpdateChartData", "save-reopen-structure");
    }
}
