VSTO - Excel Chart, Subtitle For Chart - Access Chart Text Box From Code?

Oct 14, 2011

I have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?

Dynamically Add And/or Remove Chart Series From WinForm Chart?

Mar 23, 2012

How do I dynamically add or remove a chart series on a WinForm.  To date all my MS Charting experience has been dealing with ASP.Net charts with static sql select statment to a SQL Database.  In the new project that I have been assigned I have different cities with different amounts of points that they want monitored.  One city might have 3 an another might have 5 or 7 so I can't hard code the amount of series that I need.  It needs to be set up so the amount of series can be flexible depending on the city selected and then display those points on the chart.

MS Chart AxMSChart1 - Getting Chart To Display Labels

Jul 4, 2009

I can not figure out how to get the chart to display the labels. When I try and add labels, the lines get messed up. Also, if I try and do multiple lines it does not always work out very well. I tried different ColumnLabels and they behave very strange as well. What I want is to be able to have several lines. Each with their own label. And also, I want to specify text for each point at the very bottom of the graph. Let me know what suggestions you have. [Code]

Turn A Microsoft.Office.Interop.Excel.Chart Object Into A Microsoft.Office.Tools.Excel.Chart Object?

Aug 5, 2010

Basically I've coded an Excel 2007 project in VB.NET 2010 that allows you to create charts with a fair amount of interactivity. I want the user to be able to save and reopen this workbook and still have that interactivity in any already-created charts, so they don't have to re-create them.

When I create the charts, I use Sheet1.Controls.AddChart(...), which returns a Microsoft.Office.Tools.Excel.Chart with which I can handle events and such. However, when I reopen the file and look through the Sheet1.Controls collection, there are no Chart objects. Accessing the charts through Sheet1.ChartObjects.Chart gives me Interop Charts, when I need the Tools Charts.

.net - MS Chart With ASP.NET Chart Type "column" Not Showing Axis X Label?

Mar 12, 2010

I'm having problem with MS Chart chart type column. If there are only 9 bar in the chart like the following picture, then the axis-x label show up properly.

However, there are more than 9 bars bar the chart, the axis-x label wont show up properly, some of them just dissappear.

Here's my mark-up for the chart:

<asp:Chart ID="chtNBAChampionships" runat="server">
<Series>
<asp:Series Name="Championships" YValueType="Int32" Palette="Berry"

[Code]....

I don't know it works with only 9 bars? Is there any way to make the chart work properly? Also, if possible, how to make each bar have different color.

RDLC Chart - Produce A Chart Showing The Month Along The Y-axis And The Value Up The X-axis

Jan 8, 2009

I have the smallest dataset in the world that simply consists of a month (text) and and amount. I want to produce a chart showing the month along the y-axis and the value up the x-axis. How do I do it? I have dragged the chart control onto the report page and populated the dataset. The chart shows but nothing like what I would expect. Just to make it simple I populated the dataset with an amount equivalent to the month number so it should show as 1 in January, 2 in Feb etc...However no matter where I drag the dataset's column names I don't get what I want. Where am I going wrong?

I use this simple loop to populate the dataset:

dsSales.Tables("Sales").Clear()

For i As Integer = 1 To 12
dsSales.Tables("Sales").Rows.Add(MonthName(i), i)
Next

ReportViewer1.RefreshReport()

I get this as a result:

Retrieve An Excel Chart (created Out Of .net)?

Dec 7, 2005

I am trying to retrieve an excel chart (created out of .net), which i have earlier copied to the clipboard.As long as I work with type bitmap I can copy/retrieve it as follows:

Code:' copy to clipboard (in .net)charts.CopyPicture(Office.XlPictureAppearance.xlScreen, Office.XlCopyPictureFormat.xlBitmap)
' retrieve it againimgImage=Clipboard.GetDataObject.GetData(DataFormats.Bitmap)

Unfortunately, the quality of the bitmap is rather bad, thus I would like to copy it as a Metafile. The copying works, but the retrieving will only return Nothing.

Code:' copy to clipboard (in .net)charts.CopyPicture(Office.XlPictureAppearance.xlScreen, Office.XlCopyPictureFormat.xlPicture)

' retrieve it againimgImage=Clipboard.GetDataObject.GetData(DataFormats.MetaFilePict) ' returns Nothing!

I have checked if the object is available in the clipboard using GetDataPresent and it shows that there is a metafile available. Still, it returns nothing.On a side note: Is there a way to avoid using the clipboard? After all I am creating the charts in .NET and I need them there as well. Could I access the image of the chartobject directly?

Variable For A Range In An Excel Chart Output

Sep 29, 2011

So I created a loop that collects data from the user that runs for a time dictated by the user. It then stores all the data in excel and outputs a graph.The problem I am having is that I cant seem to figure out a way to set the range of the graph for the points taken.since it runs on a loop i have i = i + 1.where the the output into the excel file sequentially writes to the next cell [code]which doesnt seem to work like I would have hoped.Also, there is one other thing that my program keeps doing that I cant seem to figure out.One of the outputs to the excel file is decimal number, it shows perfectly in the textbox, but when I export it to excel it rounds it to the nearest whole number.[code]

VS 2010 .NET Excel Chart Cell Formatting?

Dec 1, 2011

I have a program that creates a excel spreadsheet and a chart on each tab from extracted data in various .txt files. Before the chart is created, two of the excel columns will end up with data like this: on column 9 and 10. I also use data (time, looks like 09:15) in column 11 that shows the time at the bottom of the chart. There are just too many digits in the output and the readability looks bad so I can also convert.

Input Output
800400047320000
825400047120000

[code]....

The chart will display those values just fine but, normally the conversion in code that I do during the placement of that data (so it reads a bit better) looks like this:

'Convert bit to Kbit
If InRate.Length < 7 Then
InRate = CDbl(InRate) / 1000 & " Kbit"

[code]....

how to make the chart work with just numbers and ignore the MB or Kbit at the end?
