Chart Control - Assign Each Series To A New Point?
Jul 18, 2011
Im 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 .
Chart1.Dock = DockStyle.Fill
For i As Integer = 0 To 10
Dim newSeries1 As New Series[code]..........

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 think my subject sums up what I am interested in knowing. I am looking to create a chart where Series1 is from Table1, Series2 is from Table2 in the given Dataset. My code below doesn't throw any errors, but it appears to be grabbing the data for each series from the first table.
Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Public Sub New(ByVal ChartData As DataSet)
' This call is required by the designer.

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 able to place a single series of chart data with my code but I cannot for the life of me figure out how to add a second series. I can add the Series ... I can Select the series but cannot with out errors figure out how to put data the the series' that I am creating ...

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?

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.

I am using a button on a form which creates a chart at runtime when the user clicks the button. it works ok for the first time but when I select the button the second time I get a square diagonal box or indexoutofrange Exception.Note: I have another button that clears the series from the chart before reselecting the button that creates the chart.
Below is the code segment

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?

imagine 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.

I 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
Try
Dim cnRange As String = "provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source='" & strFileName & "';" & _
"Extended Properties=""Excel 8.0; IMEX=1; HDR=No;"""

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
[CODE]..................

I am working on simple handover process from one mobile station to other. I got three proposed results service disruption time, network entry time, connection set up time. I also have the result of these three as by using some conventional way and got improved these three delay results by proposed way.
Results are store in textboxes. Now i want to show graphically. E.g. I want to show conventional service disruption time on x axis and proposed service disruption time on y axis or vice versa. Let suppose I want to have a scale on axes from 1 to 3000 milliseconds. Then I want to show how purposed scheme is better. I am using VB.Net 2008

How to get values on the axes and how to generate graph? [code]
A chart element with the name '0' could not be found in the 'ChartAreaCollection'.i also tried using ChartAreas(Default") but i am getting same idea.I don't get what for this chartAreas value in parenthesis is used.

Kind of stuck with an Excel automation thing. The problem is how to change xaxis start point. The end point can be changed, with tis
CODE:
Now the xrange should be 10-100, and the plotted line is started at 10 but the xaxis is still at 0. Normally from excel it's just to format the xaxis and select for ex 10, but how to do it from VB?

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 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)

I am having trouble with .net again. I have a series of 10 text boxes. I want to be able to populate them from an array and read there values into another array. In vb6 I would create a text box array with 10 text boxes / indices. I could then populate them by txtbox(i).text = arrVal(i) and to reference them arrVal(i) = txtbox(i). I am stumped I can create 10 text boxes on a form if I have to, but I want them somehow tied to each other as they were in vb6.
