Essentially I have to show rows of bars on a stacked bar chart. There will be one for each question. Optionally there will be an extra bar or two for each question if there's a National score or a Competitor score is available.
My issue is one of presentation. I wish to place the bars central relative to the label for the question or remove gaps if one of the national or competitor scores isn't present.
Perhaps a picture will help:
I put together an example quickly (that generated the above picture) into an MVC project. These are the files:

That's a long example, but shows two different attempts at building multiple bars on a stacked chart. One using 30 columns, but splitting every 10 for each group. The second (more sensible) naming the stacks after the Value, National or Competitor they're supposed to represent.
So, in short, can I collapse the space occupied but the missing series/bars? Is it the way I'm feeding the data in perhaps?
Thanks.

I trying to merge the excel column when there is same value in the first 2 row. The value is coming from my database query. Currently what I had generated is like this:
I want to merge the column like this:
Here is my function code:
public static async Task<MemoryStream> getNewListingExcelWithContentColumnMerge<T>(List<T> list, List<string> header, string name, string headerTitle)
{
try
{
int row = 3;
int col = 1;
MemoryStream output = new MemoryStream();
using (ExcelPackage package = new ExcelPackage())
{
ExcelWorksheet ws = package.Workbook.Worksheets.Add(name);
ws.PrinterSettings.PaperSize = ePaperSize.A4;
ws.PrinterSettings.FitToPage = true;
ws.Cells["A1:D1"].Merge = true;
ws.Cells["A1:D1"].Value = headerTitle;
for (int i = 0; i < header.Count(); i++)
{
ws.Cells[row, col].Value = header[i];
col++;
}
ws.Cells[1, 1, 1, col].Style.Font.Bold = true;
col = 1;
row++;
for (int i = 0; i < list.Count(); i++)

catch (Exception ex)
{
return null;
}
}
What can I try next?
You can do it this way:
ws.Range[ws.Cells[1, 1], ws.Cells[4, 1]].Merge();
It will merge rows from 1 to 4 in column 1.
int tempRow = startRowForMerge;
int firstSameRowIndex = 0;
int lastSameRowIndex = 0;
int maxCount = tempRow + list.Count() - 1; // -1 because array start from 0
bool needToMerge = false;
foreach(int tempColumn in mergeColumnList)
{
tempRow = startRowForMerge;
for (int i = 0; i < list.Count(); i++)
{
if (tempRow < maxCount)
{
if (row > 4 && ws.Cells[tempRow, tempColumn].Value.ToString() == ws.Cells[tempRow - 1, tempColumn].Value.ToString())
{
needToMerge = true;
if (firstSameRowIndex == 0)
{
firstSameRowIndex = tempRow - 1;
}
lastSameRowIndex = tempRow;
}
else
{
if (needToMerge == true) // to merge data in between the list
{
ws.Cells[firstSameRowIndex, tempColumn, lastSameRowIndex, tempColumn].Merge = true;
ws.Cells[firstSameRowIndex, tempColumn, lastSameRowIndex, tempColumn].Style.VerticalAlignment = ExcelVerticalAlignment.Center;
needToMerge = false;
firstSameRowIndex = 0;
lastSameRowIndex = 0;
}
}
}
else
{
if (needToMerge == true) // to merge data in last row
{
ws.Cells[firstSameRowIndex, tempColumn, lastSameRowIndex, tempColumn].Merge = true;
ws.Cells[firstSameRowIndex, tempColumn, lastSameRowIndex, tempColumn].Style.VerticalAlignment = ExcelVerticalAlignment.Center;
needToMerge = false;
firstSameRowIndex = 0;
lastSameRowIndex = 0;
}
}
tempRow++;
}

I have DataGridView which consist of these data
From these data i would like to make the first column, airport name to group the third column and sum to their corresponding ActLoadQuantityTo which is in the fifth column, the cargo type which landed on the airport. right now my chart is messed up as it look like this
for (int j = 0; j < dgv_3.Rows.Count; j++)
{
double Load_qty = 0;
double new_load_qty = 0;
DiscPort = dgv_3.Rows[j].Cells["ActDiscDischargingPort"].Value.ToString();
DestType = dgv_3.Rows[j].Cells["SchLoadDestination"].Value.ToString();
CargoType = dgv_3.Rows[j].Cells["SchLoadCargoType"].Value.ToString();
string CargoType2 = "Series-" + CargoType;
Load_qty = Convert.ToDouble(dgv_3.Rows[j].Cells["ActLoadQuantityTon"].Value);
if (chart3.Series.IndexOf(DiscPort) != -1)
{
chart3.Series["000 - Port"].Points.AddY(Load_qty);
}
else
{
chart3.Series["000 - Port"].Points.AddXY(DiscPort, Load_qty);
}
}
no grouping of series,etc. i've tried adding more series but it just doesn't make sense toward the DataGridView. and my expectation is that i would like the chart to look like this as I've described before
Any idea what set of code should it be?
I found my desired result by using this code
public void isichartdomestic(System.Data.DataTable initialDataSource)
{
chart3.Titles.Add("Your title");
chart3.Legends.Add("Your Legend");
for (int i = 1; i < initialDataSource.Columns.Count; i++)
{
System.Windows.Forms.DataVisualization.Charting.Series series = new System.Windows.Forms.DataVisualization.Charting.Series();
foreach (DataRow dr in initialDataSource.Rows)
{
double y = (double)dr[i];
series.Points.AddXY(dr["DiscPort"].ToString(), y);
TotalDomestic += y;
}
chart3.Series.Add(series);
string NamaSeries = series.ToString();
NamaSeries = NamaSeries.Replace("Series-","");
chart3.Series[NamaSeries].IsValueShownAsLabel = true;
chart3.Series[NamaSeries].IsVisibleInLegend = true;
if (NamaSeries == "Series1")
{
chart3.Series[NamaSeries].LegendText = "Bag";
}
else if (NamaSeries == "Series2")
{
chart3.Series[NamaSeries].LegendText = "Bulk";
}
else if (NamaSeries == "Series3")
{
chart3.Series[NamaSeries].LegendText = "Clinker";
}
else if (NamaSeries == "Series4")
{
chart3.Series[NamaSeries].LegendText = "Container";

lb_TotalDomestic.Text = Convert.ToString("Total Domestic: " + TotalDomestic);

I have a question regarding creating controls in runtime in ASP.NET 4.0. I'm building a application and in admin.aspx page I have multiple controls (DropDownLists) which are dynamically created with values from a Sql database.
I know that for having events fired for dynamically created controls, I have to create this controls in Page_Load() or in Page_Init().
My project has a Master Page, in which I have a 1 second timer which updates a clock. This timer event calls my admin.aspx Page_Load() function, so my method which creates dynamic controls it's called every 1 second - connection to database is made every one second, please look below to my code.
It's a good practice to do that? Can you please propose some ideas?
protected void Page_Load(object sender, EventArgs e)
{
_SinopticBackgroundColor = ConfigurationManager.AppSettings["SinopticBackgroundColor"];
panelContent.Style.Add("background-color", _SinopticBackgroundColor);
Control c = GetControlThatCausedPostBack(this);
if (c != null)
{
if (c.ID.Equals("btnManageCategory"))
hfPageManage.Value = "category";
else if (c.ID.Equals("btnManageDevices"))
hfPageManage.Value = "device";
}
if (hfPageManage.Value.Equals("category"))
{
cbTreeViewGroup.Visible = false;
UpdateSinopticCategoryManager(TreeView1.SelectedNode); //this is the functions which loads controls from database..
}
else if (hfPageManage.Value.Equals("device"))
{
cbTreeViewGroup.Visible = true;
}
else
{
cbTreeViewGroup.Visible = false;
}
if (!Page.IsPostBack)
{
LoadFunctions(); // loads some values from database into datatables

I'm using the EPPlus library to read/write Excel files: http://epplus.codeplex.com/
I'm trying to simply merge some cells when writing a document:
using (ExcelPackage pck = new ExcelPackage())
{
//Create the worksheet
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo");
//Format the header for column 1-3
using (ExcelRange rng = ws.Cells["A1:C1"])
{
bool merge = rng.Merge;
}
}
There's a property named Merge that simply returns true or false. I thought maybe that would Merge the cells, but it doesn't.
Anyone know how to do this?
You have to use it like this:
ws.Cells["A1:C1"].Merge = true;
instead of:
using (ExcelRange rng = ws.Cells["A1:C1"])
{
bool merge = rng.Merge;

If you want to merge cells dynamically, you can also use:
worksheet.Cells[FromRow, FromColumn, ToRow, ToColumn].Merge = true;
All these variables are integers.
You can create a extension method:
public static void Merge(this ExcelRangeBase range)
{
ExcelCellAddress start = range.Start;
ExcelCellAddress end = range.End;
range.Worksheet.Cells[start.Row, start.Column, end.Row, end.Column].Merge = true;
}
You can use this as you would via interop:
range.Merge();
int inicio = CELDA_CUERPO;
bool values = true;
int COLUMNA_A = 0;
int finx_a = 0;
int finy_a = 0;
int COLUMNA_B = 1;
int finx_b = 0;
int finy_b = 0;
//Pintar cabecera:
for (int i = 0; i < ListaCabecera.Length; i++)
{
celda = $"{letras[i]}{CELDA_CABECERA}";
if (i == 0)
{
inicioRango = celda;
}
Sheet.Cells[celda].Value = ListaCabecera[i];
//System.Drawing.Color colFromHex = System.Drawing.ColorTranslator.FromHtml("#B7DEE8");
Sheet.Cells[celda].Style.Font.Color.SetColor(Color.FromArgb(0, 124, 183));
Sheet.Cells[celda].Style.Fill.PatternType = ExcelFillStyle.Solid;
Sheet.Cells[celda].Style.Fill.BackgroundColor.SetColor(Color.FromArgb(232, 235, 249));
Sheet.Cells[celda].Style.Font.Bold = true;
Sheet.Cells[celda].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
}
//Pintar detalle:
for (int i = 0; i < Datos.GetLength(0); i++)
{
for (int j = 0; j < Datos.GetLength(1); j++)
{
celda = $"{letras[j]}{CELDA_CUERPO + i}";
finalizaRango = celda;
if (j < 3) if (Datos[i, j].valor != null && Datos[i, j + 1].valor == null)
{
Sheet.Cells[celda].Style.Font.Color.SetColor(Color.FromArgb(156, 0, 6));
Sheet.Cells[celda].Style.Fill.PatternType = ExcelFillStyle.Solid;
Sheet.Cells[celda].Style.Fill.BackgroundColor.SetColor(Color.FromArgb(255, 199,206));
