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?

I have X and Y data columns coming from database.
I have to show scatter plot chart with Linear, Exponential, Log, power using asp.net chart control.
My requirement is to graph (scatter graph) data from 2 arrays. I can now connect the data from the array and use it on the chart. My question is, how do I set the graph's X- and Y- axes to show consistency in their intervals?

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.

I am using microsoft chart controls in VB.net. The graph data currently comes from my database, but all the series and chart formats were made before runtime. I want to know how to make charts on runtime, being able to select the x axis from my dataset and multiple y columns from my dataset.
View 1 RepliesI 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]

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.
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.
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:
I can't figure out how to plot anything on this chart...finally got it to actually display a pie chart, now I'm trying to somehow bind a data source to it and from there, select the series data..I have added the database to the project as a data source but I don't know how to bind it to the pie chart. some other info: this db has 100's of tables and the program I'm working on is going to be a "status monitor" of sorts that will contain about 6-8 different types of charts all plotting different info for me in chart form.I want to bind this one data source to all the charts and just have them display different information (based on the sql query perhaps)

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?

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?
