View 1 RepliesI 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?
View 1 RepliesBasically 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.

View 1 RepliesI 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?
I have a project that has a need to display a Excel file in second window, but because other controls are needed, simply launching excel is not sufficient.

How do I link data in an Excel spreadsheet to a chart object in Visual Basic 2010? Really basic here, I just want to draw a single simple line chart from a single column of data. Is it easier just to read the data into an array (which I can do) and somehow get it into the chart?
View 1 RepliesSo 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]
View 11 RepliesI 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?
