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 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 an ASP Chart (v4) which displays the data I need perfectly. I want it to show labels at the top of the data points and I am having some difficulty with it. Here is my code that works for both series but does not display the labels:

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. [Code]

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 deveolping a charting program and have a need to have dynamic draggable labels on the chart for notation purposes. Everything works fine until I try to drag a label past the 32767 (16 bit limit).
Here is the code that I drag the label with:
If ISDRAGGING = True Then 'DRAGGING LABEL
If CURRENTLABEL.Tag = 2 Then
CURRENTLABEL.Left = 0
[Code] .....
I have tried to create a new label and override the Top value with a Long Value, but it still does not do the trick. Hhere is my attempt to overload the top value to an integer.
Public Overloads Property Top() As Long
Get
Return _Top
End Get
Set(ByVal value As Long)
[Code] .....
The charts are dynamically generated from a database and represent depths. Usually at least 10000 feet are plotted at 5 pixels per foot. So some labels will be created or dragged below this 32767 line regularly. Any way to be able to drag the labels past this limit, or possible another option to be able to view these long 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'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.

I"m having a bit of trouble getting my pie graph to work. I'm not too sure if I should be posting here, but it's about vb so I thought it would sort of fit. I've used the chart control from the toolbox, and dragged one of those across to use. I can't get more than one item to display in the chart.

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)

I currently have a chart that plots lines of a changing value every time it is called via a timer.
Everything is running as I expected and I am happy, but now I want to be able to press a [STOP] button which will stop the timer and stop the graph from updating, (which I have coded and is now working OK), BUT I then want the code under this [STOP] button to clear everything from the graph, so when I re-start the timer, the graph is cleared and starts plotting fresh points on a clean graph.
The problem I currently have is that when I press the [STOP] button and then press the [START] button, the new lines that get plotted are "added" to the existing lines that are already on the chart, instead of having a new "blank" chart, with no data on it.
So what I am really asking is does anyone know if it is possible to reset a chart clearing everything off it so it is ready to start displaying fresh data?
I was hoping it was something like: "Chart1.Clear" or something simple like that, but I can't seem to find anything that will do it.

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)

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.
