Replace a placeholder in a existing word file with a chart

Hi.
I have an existing word file called “ExamplePlaceHolder.docx” that contains a placeholder called <<chart1>> (file attached).
I need to replace this placeholder with a Aspose Chart.
Can I have a code example that does this operation?

Thanks in advance.
Best regards

@FAIVUser Placeholder in your document is a merge field, so you can use IFieldMergingCallback to insert a chart upon executing mail merge:

Document doc = new Document(@"C:\Temp\in.docx");
doc.MailMerge.FieldMergingCallback = new InsertChartCallback();
doc.MailMerge.Execute(new string[] { "chart1" }, new object[] { "some data" });
doc.Save(@"C:\Temp\out.docx");

private class InsertChartCallback : IFieldMergingCallback
{
    public void FieldMerging(FieldMergingArgs args)
    {
        if (args.FieldName.ToLower() == "chart1")
        {
            DocumentBuilder builder = new DocumentBuilder(args.Document);
            // Move to mergefield.
            builder.MoveToField(args.Field, true);
            // Insert a chrt
            builder.InsertChart(Aspose.Words.Drawing.Charts.ChartType.Bar, 300, 200);
            // Set field value to empty string.
            args.FieldValue = "";
        }
    }

    public void ImageFieldMerging(ImageFieldMergingArgs args)
    {
        // Do nothing
    }
}

I would also suggest you to consider using LINQ Reporting Engine to create charts:
