VS 2010 Display Excel Chart On A Form?

Oct 30, 2010

I have an excel file that analizes the info on a SQL database. we have generated a few charts and now I want to be able to display them on a form in VB 2010I searched the web for info but the solutions I've found do not work and my guess is because they are for earlier versions of VB.I have been able to read or even write to the worksheet using this but on the graphvb.net

Dim oExcel As Object = CreateObject("Excel.Application")
Dim oBook As Object = oExcel.Workbooks.Open("C: est.xlsx")
Dim oSheet As Object = oBook.Worksheets(1)

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?

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 X Axis Labels - Label Display Is Inconsistent - VS 2010

Aug 2, 2011

I'm seeing a strange problem with the labels on the X axis of my charts. I've setup two chart areas and aligned them (which displays fine) and the user can manipulate the chart by selecting different date resolutions (Year, Month, Day, Week, Hour) and different time periods.

The issue I'm seeing is that if a user selects say Months as the date resolution the X axis label display is inconsistent. If a fairly broad range for the dates is selected the X axis displays absolutely fine but as the date range narrows the X axis starts to duplicate labels ( please see the attached images). The second Image had a date range of 1st of May to 1st of August and as you can see the labels are duplicated. This is my first go with the chart control so I could be missing something basic.

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]

I would like to copy a chart to another form. I have a MainForm which displays several charts.

I am unsure on how to do the actual copying part.

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.

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?

Display Results In A Chart Control?

Jun 6, 2011

I'm trying to present results on an aspx web page where a store procedure parameter is defined by a dropdown list control on the page. I have followed this guide from Microsoft and have my resultset presented in a DataGrid view. But I cannot seem to adapt it to present the resultset in a chart.

As you can see from my VB code below, I thought it would simply be a case of adapting the GridView databind to a Chart. I have tried various other options, and have successfully generated my data in a chart using a hard-coded parameter in an SQL statement on the ASP page. But when it comes to using the control, I get an empty chart.

Below is what I have so far.

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]

Primary X Axis In MS Chart Control Won't Display Max Value?

Jul 21, 2011

I am using MS chart control .net 4 framework in Visual studio 2010 using Windows forms. I am having an issue with the scale of the primary x axis on a user input from a text box on a button click. I am also using both the primary and secondary y axes which work on a user input.

I have checked the settings for each axis and they all have the same settings. I don't see why both y axes work on the user input and the x does not.

The following is the code I am using:

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Chart1.ChartAreas("Area1").AxisX.Minimum = Val(XPrimeMin.Text)
