I am using EPPlus library to generate pivot chart in excel.
I created the chart but don't know how I can add "Series Lines" to it.
The arrow in the below image indicates series lines.
Chart - Series Lines
Here is the sample code.
var wsBar = pck.Workbook.Worksheets.Add("Bar");
--dataRange = Data from "Data" worksheet.
var pivotTable1 = wsBar.PivotTables.Add(wsBar.Cells["Z100"], dataRange, "pivotTable1");
var dataFieldBar1 = pivotTable1.DataFields.Add(pivotTable1.Fields[22]);
dataFieldBar1.Format = "$ #,###.00";
pivotTable1.DataOnRows = true;
pivotTable1.RowFields.Add(pivotTable1.Fields[15]);
pivotTable1.ColumnFields.Add(pivotTable1.Fields[12]);
pivotTable1.PageFields.Add(pivotTable1.Fields[7]);
var columnchart = wsBar.Drawings.AddChart("ColumnChart", eChartType.ColumnStacked, pivotTable1);
columnchart.SetPosition(0, 0, 0, 0);
columnchart.SetSize(600, 300);
Any help is highly appreciated.
Dont think EPPlus has that as an option so it would be some kind of XML manipulation without another library:
var chartXml = columnchart.ChartXml;
var nsm = new XmlNamespaceManager(chartXml.NameTable);
var nsuri = chartXml.DocumentElement.NamespaceURI;
nsm.AddNamespace("c", nsuri);
var serNode = chartXml.SelectSingleNode("c:chartSpace/c:chart/c:plotArea/c:barChart", nsm);
var serLinesNode = chartXml.CreateNode(XmlNodeType.Element, "serLines", nsuri);
serNode.AppendChild(serLinesNode);

I've been trying to set the column width for my table, but it won't budge. I'm using NPOI from this git https://github.com/nissl-lab/npoi.
Currently, my code is:
FileStream stream = new FileStream(reportPath, FileMode.Open);
XWPFDocument doc = new XWPFDocument(stream);
XWPFTable table;
table = doc.CreateTable(1, 3);
table.SetColumnWidth(0, (ulong)1000);
table.SetColumnWidth(1, (ulong)2000);
table.SetColumnWidth(2, (ulong)3000);
using (var f = File.Create(reportPath)) doc.Write(f);
And the generated columns are in the same size having the smallest column size possible. Also, I'm trying to generate a DOCX file.
You have to set the table width type to make it work.
XWPFTable table1 = doc.CreateTable(1, 3);
var tblLayout1 = table1.GetCTTbl().tblPr.AddNewTblLayout();
tblLayout1.type = ST_TblLayoutType.#fixed;
table1.SetColumnWidth(0, 1000);
table1.SetColumnWidth(1, 2000);
table1.SetColumnWidth(2, 3000);
The above code works in NPOI 2.5.4
I generate an Excel sheet which contains data formatted like so:
IOW, the "Total Packages", "Total Purchases", "Average Price", and "% of Total" values are located in a column of their own (Data) for each overarching (or sidearching) description.
When I PivotTablize this data, it places these values beneath each description:
This makes sense, but those accustomed to the previous appearance want it to be replicated in the PivotTable. How can I shift the Description "subitems" in the PivotTable to their own column?
This is the code I use to generate the PivotTable:
private void PopulatePivotTableSheet()
{
string NORTHWEST_CORNER_OF_PIVOT_TABLE = "A6";
AddPrePivotTableDataToPivotTableSheet();
var dataRange = rawDataWorksheet.Cells[rawDataWorksheet.Dimension.Address];
dataRange.AutoFitColumns();
var pivotTable = pivotTableWorksheet.PivotTables.Add(
pivotTableWorksheet.Cells[NORTHWEST_CORNER_OF_PIVOT_TABLE],
dataRange,
"PivotTable");
pivotTable.MultipleFieldFilters = true;
pivotTable.GridDropZones = false;
pivotTable.Outline = false;
pivotTable.OutlineData = false;
pivotTable.ShowError = true;
pivotTable.ErrorCaption = "[error]";
pivotTable.ShowHeaders = true;
pivotTable.UseAutoFormatting = true;
pivotTable.ApplyWidthHeightFormats = true;
pivotTable.ShowDrill = true;
// Row field[s]
var descRowField = pivotTable.Fields["Description"];
pivotTable.RowFields.Add(descRowField);
// Column field[s]
var monthYrColField = pivotTable.Fields["MonthYr"];
pivotTable.ColumnFields.Add(monthYrColField);
// Data field[s]
var totQtyField = pivotTable.Fields["TotalQty"];
pivotTable.DataFields.Add(totQtyField);
var totPriceField = pivotTable.Fields["TotalPrice"];
pivotTable.DataFields.Add(totPriceField);
// Don't know how to calc these vals here, so have to grab them from the source data sheet
var avgPriceField = pivotTable.Fields["AvgPrice"];
pivotTable.DataFields.Add(avgPriceField);
var prcntgOfTotalField = pivotTable.Fields["PrcntgOfTotal"];
pivotTable.DataFields.Add(prcntgOfTotalField);
}
So there is one RowField ("MonthYr") with values such as "201509" and "201510", one ColumnField ("Description") and four DataFields, which align themseles under the Description column field. I want to shift those four fields to the right, to their own column, and the Description label to be vertically centered between those four values to their left. [How] is this possible?
Try changing the layout of your table with
pivotTable.RowAxisLayout xlTabularRow
pivotTable.MergeLabels = True
this is the result:
A little script in C# with Interop.Excel. Included the using ;)
using Microsoft.Office.Interop.Excel;
using System.Runtime.InteropServices;
using Excel = Microsoft.Office.Interop.Excel;
var excelApp = new Excel.Application();
Excel.Workbook wb = excelApp.Workbooks.Open(#"e:\42\TestSO.xlsx");
Worksheet ws = wb.Worksheets["SheetName"];
PivotTable pt = ws.PivotTables("DynamicTableName");
pt.RowAxisLayout(XlLayoutRowType.xlTabularRow);
pt.MergeLabels = true;
wb.Save();
wb.Close();
Marshal.ReleaseComObject(ws);
It's all about PivotTable layout / design... here's the manual way - Salvador has the VBA way :)...
Is there a way in MigraDoc to make an entire table cell a link? I have a tabular table of contents, and the page number is difficult to click. I would prefer if the entire cell was clickable to navigate to a specified page. Here is an example of my code:
// Create the table within the document
var document = new Document();
var section = document.AddSection();
var table = section.AddTable();
// Create a column in the table
var column = table.AddColumn();
column.Width = "2cm";
// Create a row in the table
var row = table.AddRow();
row.Height = "1cm";
// Add a hyperlink to the appropriate page
var paragraph = row.Cells[0].AddParagraph();
var hyperlink = paragraph.AddHyperlink("MyBookmarkName");
hyperlink.AddPageRefField("MyBookmarkName");
...
// Create the bookmark later in the document
I'm afraid there is no easy way to make the whole cell clickable. I haven't tried it myself, but you can add images (visible or transparent) or text to the hyperlink.
This will make the clickable area bigger - and if you use e.g. blue underlined text there will be a visual hint that the text is clickable.
I was inspired by the answer from the PDFsharp Team to try and fill the cell with a blank hyperlink image, with text over the hyperlink. Since my ultimate goal was to actually make an entire row a hyperlink, I came up with the following solution.
First, add an additional zero-width column prior to the first column in the table that you want to be a hyperlink. Next, add a paragraph, hyperlink, and transparent 1-pixel image to each zero-width cell. Specify the image height and width to fill however many table cells you want to be a link. Also, be sure to set the font size of the paragraph containing the link to nearly zero (zero throws an exception, but images are aligned on the font baseline, so you need a very small number to prevent the paragraph from being larger than the image).
Note that a zero-width column, even with borders, does not change the apparent border width when viewing the resulting PDF. The following code illustrates my approach:
// Declare some constants
var _rowHeight = new Unit(.75, UnitType.Centimeter);
// Create the document, section, and table
var document = new Document();
var section = document.AddSection();
var table = section.AddTable();
// Format the table
table.Rows.Height = _rowHeight;
table.Rows.VerticalAlignment = VerticalAlignment.Center;
// Define the column titles and widths
var columnInfos = new[] {
new { Title = "Non-Link Column", Width = new Unit(8, UnitType.Centimeter) },
new { Title = "" , Width = new Unit(0 ) },
new { Title = "Link Column 1" , Width = new Unit(8, UnitType.Centimeter) },
new { Title = "Link Column 2" , Width = new Unit(8, UnitType.Centimeter) },
};
// Define the column indices
const int colNonLink = 0;
const int colHyperlink = 1;
const int colLink1 = 2;
const int colLink2 = 3;
// Create all of the table columns
Unit tableWidth = 0;
foreach (var columnInfo in columnInfos)
{
table.AddColumn(columnInfo.Width);
tableWidth += columnInfo.Width;
}
// Remove the padding on the link column
var linkColumn = table.Columns[colHyperlink];
linkColumn.LeftPadding = 0;
linkColumn.RightPadding = 0;
// Compute the width of the summary links
var linkWidth = tableWidth -
columnInfos.Take(colHyperlink).Sum(ci => ci.Width);
// Create a row to store the column headers
var headerRow = table.AddRow();
headerRow.Height = ".6cm";
headerRow.HeadingFormat = true;
headerRow.Format.Font.Bold = true;
// Populate the header row
for (var colIdx = 0; colIdx < columnInfos.Length; ++colIdx)
{
var columnTitle = columnInfos[colIdx].Title;
if (!string.IsNullOrWhiteSpace(columnTitle))
{
headerRow.Cells[colIdx].AddParagraph(columnTitle);
}
}
// In the real code, the following is done in a loop to dynamically add rows
var row = table.AddRow();
// Populate the row header
row.Cells[colNonLink].AddParagraph("Not part of link");
// Change the alignment of the link cell
var linkCell = row.Cells[colHyperlink];
linkCell.VerticalAlignment = VerticalAlignment.Top;
// Add a hyperlink that fills the remaining cells in the row
var linkParagraph = linkCell.AddParagraph();
linkParagraph.Format.Font.Size = new Unit(.001, UnitType.Point);
var hyperlink = linkParagraph.AddHyperlink("MyBookmarkName");
var linkImage = hyperlink.AddImage("Transparent.gif");
linkImage.Height = _rowHeight;
linkImage.Width = linkWidth;
// Populate the remaining two cells
row.Cells[colLink1].AddParagraph("Part of link 1");
row.Cells[colLink2].AddParagraph("Part of link 2");
// Add a border around the cells
table.SetEdge(0, 0, columnInfos.Length, table.Rows.Count,
Edge.Box | Edge.Interior, BorderStyle.Single, .75, Colors.Black);
The result of the above code is a document containing a table with 2 rows, 3 visible columns, where the entirety of the last two cells in the final row are a hyperlink to "MyBookmarkName". Just for reference, I did modify the PDFSharp source code according to the advice here to remove borders around hyperlinks, which looked wonky at certain zoom levels in Adobe Acrobat Reader.
I am working with Aspose slides to generate PPT in my application, I ran into a situation where I need to insert HTML text into Table Cell, I verified all blogs no one given answer to me. If any body know here please let me know. Thanks In advance.
You can use the TextFrame's paragraph associated with each cell to insert HTML using Aspose.Slides for .NET. Check the following code:
//Instantiate Presentation class that represents PPTX file
using (Presentation pres = new Presentation())
{
//Access first slide
ISlide sld = pres.Slides[0];
//Define columns with widths and rows with heights
double[] dblCols = { 250, 250};
double[] dblRows = { 150, 130, 130 };
//Add table shape to slide
ITable tbl = sld.Shapes.AddTable(100, 50, dblCols, dblRows);
//Set border format for each cell
foreach (IRow row in tbl.Rows)
foreach (ICell cell in row)
{
cell.BorderTop.FillFormat.FillType = FillType.Solid;
cell.BorderTop.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderTop.Width = 5;
cell.BorderBottom.FillFormat.FillType = FillType.Solid;
cell.BorderBottom.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderBottom.Width = 5;
cell.BorderLeft.FillFormat.FillType = FillType.Solid;
cell.BorderLeft.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderLeft.Width = 5;
cell.BorderRight.FillFormat.FillType = FillType.Solid;
cell.BorderRight.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderRight.Width = 5;
}
//Adding html text in text frame
tbl[0, 0].TextFrame.Paragraphs.AddFromHtml(#"<html><body><p><b>This text is bold</b></p>
<p><i>This text is italic</i></p><p>This is<sub> subscript</sub> and <sup>superscript</sup></p>
</body></html>");
//Write PPTX to Disk
pres.Save("d:\\data\\table_html.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}
P.S. I am working as social media developer at Aspose.
How do I create a graph as a separate worksheet rather than as a drawing in an existing worksheet using EPPLus?
In version 4.0.4.0 (download the code from codeplex, for correct a bug in saving file), you can use:
workbook.Worksheets.AddChart(name, type);
this will create a sheet with only the chart.
You should do what you want. That is the chart you want to plot, plot it in the sheet you want.
ExcelPackage pck = new ExcelPackage();
ExcelRange r1, r2;
var sheet1 = pck.Workbook.Worksheets.Add("data_sheet");
var sheet2 = pck.Workbook.Worksheets.Add("chart_sheet");
var chart = (OfficeOpenXml.Drawing.Chart.ExcelBarChart)sheet2.Drawings.AddChart("some_name", OfficeOpenXml.Drawing.Chart.eChartType.ColumnClustered);
chart.Legend.Position = OfficeOpenXml.Drawing.Chart.eLegendPosition.Right;
chart.Legend.Add();
chart.SetPosition(1, 0, 1, 0);
chart.SetSize(600, 400);
chart.DataLabel.ShowValue = true;
r1 = sheet1.Cells["A3:A10"];
r2 = sheet1.Cells["B3:B10"];
chart.Series.Add(r2, r1);
chart.Style = OfficeOpenXml.Drawing.Chart.eChartStyle.Style21;
chart.Title.Text = "Some title";
chart.XAxis.Title.Text = "X axis name";
chart.YAxis.Title.Text = "Y axis name";
In this example, chart is plotted in sheet2 but data is in sheet1.
Hope this is helpful.
