Use the following code to create the document: 

            Workbook workbook = new Workbook();
            Worksheet graphWorksheet = workbook.Worksheets.Add();
            FloatingChartShape chartShape = new FloatingChartShape(graphWorksheet,
                                         new CellIndex(0, 0),
                                         new CellRange(0, 0, 0, 0), ChartType.Column)
            {
                Width = 500,
                Height = 500,
            };

            graphWorksheet.Charts.Add(chartShape);
            DocumentChart chart = new DocumentChart();
            BarSeriesGroup barSeriesGroup = new BarSeriesGroup();
            barSeriesGroup.BarDirection = BarDirection.Column;
            StringChartData barCategoryData = new StringChartData(new List<string>() { "1.1", "1.2", "1.3", "1.4", "2.1", "3.1", "4.1", "4.2", "4.3" });
            IEnumerable<double> percentEvidentList = new List<double>() { Math.Round((double)0.9914 * 100, 4) , Math.Round((double)0.7719 * 100, 4), Math.Round((double)1 * 100, 4)   };
            NumericChartData barValues = new NumericChartData(percentEvidentList);
            BarSeries series = new BarSeries();
            series.Categories = barCategoryData;
            series.Values = barValues;
            ThemableColor themableColor = ThemableColor.FromArgb(255, 125, 0, 125);

            series.Fill = new SolidFill(themableColor);
            series.Title = new TextTitle("FY 20");
            barSeriesGroup.Series.Add(series);
            chart.SeriesGroups.Add(barSeriesGroup);
            ValueAxis valueAxis = new ValueAxis();
            valueAxis.Min = 0;
            valueAxis.Max = 100;
            valueAxis.NumberFormat = "0%";
            CategoryAxis categoryAxis = new CategoryAxis(); 
            chart.PrimaryAxes = new AxisGroup(categoryAxis, valueAxis);

            chart.Legend = new Legend();
            chart.Legend.Position = LegendPosition.Left;

            chartShape.Chart = chart;
            valueAxis.NumberFormat = "0%";
            string outputFilePath = "SampleFile.xlsx";
            File.Delete(outputFilePath);
            IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();

            using (Stream output = new FileStream(outputFilePath, FileMode.Create))
            {
                formatProvider.Export(workbook, output, TimeSpan.FromSeconds(10));
            }
            Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });

Getting an exception message when trying to view a document as a PDF using the PdfFormatProvider which started happening only after upgrading Telerik to the latest version, 7.1.0 in Telerik UI for Blazor.

Exception Message:

width should be greater or equal than 0. (Parameter 'width')

I have copied the stack trace and source of the exception below:

Implement repeating header row for tables when exporting with PdfFormatProvider.

A similar functionality can be achieved using the editing API of RadPdfProcessing. There is attached a project showing a sample implementation. More details are available in the forum post at http://www.telerik.com/forums/repeat-table-heading-after-page-break#kH616fyAKUiDl6WAknUILg

When you have indented and justified text, it is wrongly exported to PDF:

			<w:pPr>
				<w:spacing w:after="0" w:line="360" w:lineRule="auto"/>
				<w:ind w:left="567" w:right="567" w:firstLine="708"/>
				<w:jc w:val="both"/>
				<w:rPr>
					<w:rFonts w:ascii="Calibri Light" w:hAnsi="Calibri Light"/>
				</w:rPr>
			</w:pPr>

Add support for actions with invalid Subtype casing.

Example: The action Subtype being "Javascript" instead of the expected "JavaScript".

Add support for Arrange Options (level placement):

• Bring to Front
• Send to Back
• Bring Forward
• Send Backward

Some fonts are not measured correctly by RadTextMeasurer.
