Excel Scatterplot Chart From List (Of Decimal) Values - .NET?

May 17, 2012

Is it possible to create a plot from List(Of Decimal) values in Excel with VB? I would like to avoid dumping data directly into a table, then creating the chart from that. Here is what I have so far, but I am getting a data type mismatch when I try to assign .XValues and .Values to the list. Is there some sort of conversion that needs to happen to turn a list into a series?

Dim Series As Excel.Series
Dim xVals As New List(Of Decimal)(New Decimal() {1, 3, 4, 5})
Dim yVals As New List(Of Decimal)(New Decimal() {2, 2, 2, 2})

[code].....

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?

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.

Displaying A Chart For Values?

Dec 24, 2011

i have a dice program that will find the random numbers according to user input as regards dice and throws required. My problem is when i have to display all the values in a listbox but in a horizontal type, were if a value came out more than once it displays the number and a bar for each time it come out and also at the end show the count of the times the number came out, to have a better idea the final chart needs to be displayed in the following format in a listbox as in the long run the program needs to run in a web application, but i am writing and testing in a window form application, then i will transfer to web application and use session variables and timers to control the output and the graph.

3 ||||||||| - 9
5 ||| - 3
6 ||||||- 6
10 ||||||||| - 9
2 | - 1

My code till now is that i have a class were a roll dice method and a similar values method are kept and from the form in the roll button these two methods are called and the results are shown in two listboxes one for how the roll dice random numbers with duplicates is shown and the other listbox displays only the numbers without duplicates.Also another method for the graph is in the class clsNDie but it seems that i have something wrong it this area?

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?

Chart Setup - Dynamically Changing Values Via Dropdown

Mar 7, 2011

How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically.
