Is there is a way to remove the white box around the series label in a chart. I am using the built in chart from the toolbox in Visual Studio 2010. This is the last part I need to finish the appearance of the chart to make it look the way I want.

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 have a set of charts in a form. These are "canned" charts and will only be updated when new data comes in (typically on a monthly basis). I have created each chart by binding (bounding?) a data source to it in VS2010 using the Properties slide out window. I set the DataSource to a data source table that I set up in the .XSD file. In the Series property GUI I have set up the XValueMember and YValueMembers from the available columns in the data table I set in the previous step. I have 6 tables in my DataSet. One table relates to one Chart (Chart1, Chart2, Chart3, etc) in my form.
What I would like to do is programmatically get the data table name from the Chart properties. I have tried doing something like:
ch1Table = Chart1.DataSource.DataMember.ToString
However this fails due to Option Strict disallowing late binding. I am probably missing something obvious here but I cannot see it.
So, how do I get the bound data table name from the set properties of the chart? I am using MSChart Control 4 and VS2010 and building a VB.NET WinForms app.
For each of the 6 charts there is an associated System.Windows.Forms.BindingSource. What I need to do is programmatically get that BindingSource, then get the DataMember (which is the table name I need) for each chart.
Apply a generic template to chart series.[code]Note that the bars are unstyled while the chart seems to style just fine.The documentation regarding built-in .NET charting is woefully thin.Can anyone help me get my generic templates to work?
View 1 RepliesIm starting to learn how to use the chart control in VB .how you create a "new" column because atm all the time i add series it puts them side by side.Ive looked at the documentation for the control and the examples but they dont seem to cover this , or i could find it .Now how would i assign each series to a new point?So item 1 would go above column 1 and item 2 above column 2 etc.The code i have at the moment is a test code .

Im trying to plot the reading of 20 or more thermocouples in a single chart area.But it seems that the build in charting in vb.net can't handle that. My program just crashes when adding a series somwhere between the 14th or 18th series.Anyone know of any setting i can change or a better charting plugin?
View 2 Repliesimagine an array of data containing a gray scale image and you want the bar chart (say 20x20) to display a section of that image as both the magnitude of the data and its shade of gray. if you were to look vertically down on the 3D barGraph you should see the section of the image. Is this at all possible? The projetc relates to clutter intensity in a radar image if this interests you.
View 2 RepliesI am importing data from an excel file, and it is stored in a dataset. The data is then filtered with a binding source, and that data is outputted into a datagridview. The filtered data in the datagridview contains data for 2 identification numbers. I want to graph each ID number in a chart on their own bar, in either a stacked bar graph, or a double bar graph.
I am having trouble assigning each series to an ID number: I have tried using multiple binding sources, but each seems to override the previous giving too much/too little data. I have tried using multiple datagridviews, however I cannot assign more than one datagridview as the datasource for the chart. The code I have pasted below outputs a double bar graph, however both bars graph the same ID number.
Private Sub dataButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dataButton.Click

Dim cnRange As String = "provider=Microsoft.Jet.OLEDB.4.0; " & _

I am trying to build a function that returns a chart. I want to have a parameter to account for times where i may need more than one series. How does one loop through to create multiple series? I would think you would need a variable for each series. The function is below. I would think that if there were 5 series that each of the "Dataseries" variables should have their own name. Do I then refer to them by index only?

I have an array of type Double() (1 x n) that I am trying to quickly plot on a graph I've already set up. The only thing I want/need to do is take my array and store it as data points (y-axis values) in the series I already have. What's the best way to do this? Also, will the data points that are plotted change as my array changes, and if not, how would I replot those new points and get rid of the old points?

I'm working in VS2010 on a visual basic application. It takes in serial port data, writes it to an access database, and then graphs the data.The data only comes in once every minute, so it's not like I'm building an oscilloscope. Right now, the chart is reading from the database using a table adapter and graphing just fine, so long as I keep the number of records in the database low.If I add too many records to the database, the chart shows a red "X" through it. I've played with changing the axes, but it is still a problem.I don't really need to graph the whole database.The twenty most recent records would suffice.How can I make a chart series with only a small subset of the database in it.Perhaps it cold be populated with a query?

I am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.
Example Data:
[CODE]...........
Case Select (with commented out lines for variations attempted):
[CODE]..........
1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):
[CODE]..........
Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):
[CODE]..........
So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?
2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?
Example code for the StoredProcedure and creating the new form:
If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart

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.

View 8 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.

View 1 RepliesI'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]
