How to create redar diagram in excel using Epplus in dotnet 6

I have created report in excel sheet which Is described in image1 and this image should give redar diagram which in in Image2 in different excel sheet like given in screenshot.
there are two excel sheet in one excel as you can see in screenshot so in chart sheet there should be redar diagram and sheet named sheet there is excel report valud as you can see in screenshot
I have already done piechart and excel report as well and I get stocked while making redar diagram ,
example of that I had made piechart and excel report :
public static class TestRunTestCaseExportHelper {

Switch document renderer - Cannot draw elements on already flushed pages

According to this case's answer by Alexey, we can utilize different renderers with customized RootLayoutArea to achieve such layout behavior as below.
Here is the code:
public void ManipulatePdf(String dest)
{
PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
Document doc = new Document(pdfDoc, PageSize.A4);
doc.SetMargins(36, 36, 36, 36);
Paragraph p = new Paragraph();
p.SetBorder(new SolidBorder(0.5f));
for (int i = 1; i <= 500; i++)
{
p.Add(new Text(i + " "));
}
doc.Add(p);
RootLayoutArea endOfFullWidthContentArea = (RootLayoutArea)doc.GetRenderer().GetCurrentArea();
ExtendedDocumentRenderer renderer1 = new ExtendedDocumentRenderer(doc,
new RootLayoutArea(endOfFullWidthContentArea.GetPageNumber(), endOfFullWidthContentArea.GetBBox().Clone().SetWidth(200)));
doc.SetRightMargin(doc.GetRightMargin() + doc.GetPageEffectiveArea(PageSize.A4).GetWidth() - 200);
doc.SetRenderer(renderer1);
//The paragraph drawn in the left
Paragraph p1 = new Paragraph();
p1.SetBorder(new SolidBorder(0.5f));
for (int i = 1; i <= 500; i++)
{
p1.Add(new Text(i + " "));
}
doc.Add(p1);
ExtendedDocumentRenderer renderer2 = new ExtendedDocumentRenderer(doc,
new RootLayoutArea(endOfFullWidthContentArea.GetPageNumber(),
endOfFullWidthContentArea.GetBBox().Clone().MoveRight(200 + 20)
.SetWidth(endOfFullWidthContentArea.GetBBox().GetWidth() - 200 - 20)));
doc.SetRightMargin(36);
doc.SetLeftMargin(200 + 36 + 20);
doc.SetRenderer(renderer2);
Paragraph p2 = new Paragraph();
for (int i = 1; i <= 1000; i++)
{
p2.Add(new Text(i + " "));
}
doc.Add(p2);
//Compute which free area is lower in the document
RootLayoutArea areaColumn1 = (RootLayoutArea)renderer1.GetCurrentArea();
RootLayoutArea areaColumn2 = (RootLayoutArea)renderer2.GetCurrentArea();
RootLayoutArea downArea =
areaColumn1.GetPageNumber() > areaColumn2.GetPageNumber() ? areaColumn1 :
(areaColumn1.GetPageNumber() < areaColumn2.GetPageNumber() ? areaColumn2 :
(areaColumn1.GetBBox().GetTop() < areaColumn2.GetBBox().GetTop() ? areaColumn1 : areaColumn2));
doc.SetMargins(36, 36, 36, 36);
DocumentRenderer renderer3 = new ExtendedDocumentRenderer(doc,
new RootLayoutArea(downArea.GetPageNumber(), downArea.GetBBox().Clone().SetX(36).SetWidth(doc.GetPageEffectiveArea(PageSize.A4).GetWidth())));
doc.SetRenderer(renderer3);
Paragraph p3 = new Paragraph();
for (int i = 1; i <= 1000; i++)
{
p3.Add(new Text(i + " "));
}
doc.Add(p3);
doc.Close();
}
private class ExtendedDocumentRenderer : DocumentRenderer
{
public ExtendedDocumentRenderer(Document document, RootLayoutArea currentArea) : base(document)
{
this.currentArea = new RootLayoutArea(currentArea.GetPageNumber(), currentArea.GetBBox().Clone());
this.currentPageNumber = this.currentArea.GetPageNumber();
}
}
We can see that the Paragraph 1 in the left column spans two pages, and the Paragraph 2 spans three pages, under this scenario the code runs well.
But if we add more contents to Paragraph 1 and make it span 3 pages as following:
//The paragraph drawn in the left has more contents
Paragraph p1 = new Paragraph();
p1.SetBorder(new SolidBorder(0.5f));
for (int i = 1; i <= 800; i++)
{
p1.Add(new Text(i + " "));
}
doc.Add(p1);
When the Paragraph 2 is rendering, it throws the exception of "Cannot draw elements on already flushed pages". How to solve this problem? Thank you!

If you elements can span multiple pages then you need to apply immediateFlush=false setting of the DocumentRenderer which goes to its constructor.
You will need to modify your ExtendedDocumentRenderer custom implementation in the following way:
private class ExtendedDocumentRenderer : DocumentRenderer
{
public ExtendedDocumentRenderer(Document document, RootLayoutArea currentArea) : base(document, false)
{
this.currentArea = new RootLayoutArea(currentArea.GetPageNumber(), currentArea.GetBBox().Clone());
this.currentPageNumber = this.currentArea.GetPageNumber();
}
}
And then you will need to call Document#Flush whenever you are done with another document renderer. Essentially in your code sample that call needs to be done after adding each new element. Here is the full code:
Document doc = new Document(pdfDocument, PageSize.A4);
doc.SetMargins(36, 36, 36, 36);
Paragraph p = new Paragraph();
p.SetBorder(new SolidBorder(0.5f));
for (int i = 1; i <= 500; i++)
{
p.Add(new Text(i + " "));
}
doc.Add(p);
RootLayoutArea endOfFullWidthContentArea = (RootLayoutArea)doc.GetRenderer().GetCurrentArea();
ExtendedDocumentRenderer renderer1 = new ExtendedDocumentRenderer(doc,
new RootLayoutArea(endOfFullWidthContentArea.GetPageNumber(), endOfFullWidthContentArea.GetBBox().Clone().SetWidth(200)));
doc.SetRightMargin(doc.GetRightMargin() + doc.GetPageEffectiveArea(PageSize.A4).GetWidth() - 200);
doc.SetRenderer(renderer1);
//The paragraph drawn in the left
Paragraph p1 = new Paragraph();
p1.SetBorder(new SolidBorder(0.5f));
for (int i = 1; i <= 800; i++)
{
p1.Add(new Text(i + " "));
}
doc.Add(p1);
doc.Flush();
ExtendedDocumentRenderer renderer2 = new ExtendedDocumentRenderer(doc,
new RootLayoutArea(endOfFullWidthContentArea.GetPageNumber(),
endOfFullWidthContentArea.GetBBox().Clone().MoveRight(200 + 20)
.SetWidth(endOfFullWidthContentArea.GetBBox().GetWidth() - 200 - 20)));
doc.SetRightMargin(36);
doc.SetLeftMargin(200 + 36 + 20);
doc.SetRenderer(renderer2);
Paragraph p2 = new Paragraph();
for (int i = 1; i <= 1000; i++)
{
p2.Add(new Text(i + " "));
}
doc.Add(p2);
doc.Flush();
//Compute which free area is lower in the document
RootLayoutArea areaColumn1 = (RootLayoutArea)renderer1.GetCurrentArea();
RootLayoutArea areaColumn2 = (RootLayoutArea)renderer2.GetCurrentArea();
RootLayoutArea downArea =
areaColumn1.GetPageNumber() > areaColumn2.GetPageNumber() ? areaColumn1 :
(areaColumn1.GetPageNumber() < areaColumn2.GetPageNumber() ? areaColumn2 :
(areaColumn1.GetBBox().GetTop() < areaColumn2.GetBBox().GetTop() ? areaColumn1 : areaColumn2));
doc.SetMargins(36, 36, 36, 36);
DocumentRenderer renderer3 = new ExtendedDocumentRenderer(doc,
new RootLayoutArea(downArea.GetPageNumber(), downArea.GetBBox().Clone().SetX(36).SetWidth(doc.GetPageEffectiveArea(PageSize.A4).GetWidth())));
doc.SetRenderer(renderer3);
Paragraph p3 = new Paragraph();
for (int i = 1; i <= 1000; i++)
{
p3.Add(new Text(i + " "));
}
doc.Add(p3);
doc.Flush();
doc.Close();

After stepping on the pit before, you can try calling three parameter constructors and setting immediateflush to false.
PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
// setting immediateflush to false
Document doc = new Document(pdfDoc, PageSize.A4, false);

iTextSharp Pdftable Issue

I am facing issue while generating pdf from Windows form using iTextSharp dll. I am populating more than 70 records at a time in a dataset and I am binding same to new table(pdfptable) by looping. But it says Object reference not set to instance of object. when I reduced number of rows to 68 it works fine. After analysis I found that table is not able to split along the multiple pages.
I am using following piece of code. Please help
float[] widths1 = new float[] { 1f, 2f,1f,1f,1f,1f,1f};
PdfPTable grd = new PdfPTable(GrdAnoSecList.Columns.Count);

how to set large table on next pages if contain is large with iTextSharp

I've added an header and a footer on my document by PdfPageEventHelper.
The document has several "large" tables populated at runtime.
I've tried to add those tables simply by "documen.Add(table)", but my header and my footer results overwritten.
I've already tried both methods to add the tables (WriteSelectedRows and document.Add(myPdfPtable).
Here is the code of the PageEventHelper for Head:
public override void OnEndPage(PdfWriter writer, Document doc)
{
Phrase phrase = null;
PdfPCell cell = null;
PdfPTable maintable = new PdfPTable(2);
maintable.TotalWidth = 500f;
maintable.LockedWidth = true;
maintable.SetWidths(new float[] { 50f, 400f });
#region checklogo
if (IsLogo!=0)
{
// code for display head like logo, etc
}
#endregion CheckSchoolNameandAddress
maintable.WriteSelectedRows(0, -1, 50, 835, writer.DirectContent);
Color color = new Color(System.Drawing.ColorTranslator.FromHtml("#A9A9A9"));
DrawLine(writer, 25f, 780f, doc.PageSize.Width - 25f, 780f,color);
DrawLine(writer, 25f, 780f, doc.PageSize.Width - 25f, 780f, color);
}
Here is the code of the PageEventHelper for footer:
public override void OnEndPage(PdfWriter writer, Document doc)
{
Phrase phrase = null;
PdfPCell cell = null;
PdfPCell cell1 = null;
PdfPCell cell2 = null;
int pageN = writer.PageNumber;
String text = "Page " + pageN;
PdfPTable foootertable = new PdfPTable(3);
