Chart Control - Bind Data To Different Series From Tables In DataSet?
Nov 30, 2011
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.
InitializeComponent()
[Code] .....
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 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.

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 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 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?
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 Visual Basic 2008 Pro. I am trying to figure out how to bind a set of column headings in a DataSet (or DataGridView) to a ListBox. I want to show the column headers in the listbox control (not the data), and allow users to select one or more items
How do you plot data from a dataset or datatable. I have loaded a dataset with data from the database and now cannot do the plotting. When I tried: myChart.dataContext=ds("myTable").defaultView, no chart shows. If I replace: dataContext with: dataSource, I get an error. I am using WPF not Windows Forms.
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
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click Static Dim counter As Integer = 0
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 have a VB.Net dataset that contains data from multiple tables. how to query data out of the dataset. I want to run SQL-like queries on a dataset to extract data that fits a certain "where" statement.
The situation: I have a small application where i store customers and orders.. In my database i have a tabel called Customers and a tabel called Orders. These 2 dabases are joined on Customer ID - every Order record contain a row with the customer Id.
I have an office project which shoudl basically do the following:
1) take different TEXT files of fixed-length fields and put them in separate tables.
2) use the data from the different tables and compile them to a master table in a mdb.
3) display data in compiled mdb in datagrid 4) allow editing in datagrid 5) save the data in datagrid into the mdb 6) save the data in datagrid in a csv file i did some googling and came up with the following code:
I need to fill a datatable(in data set) row by row by providing the the data by variables in VB.Net. The variables assigns its value by loop.. so the datatable row should be filled row by row until the loop ends. There are three columns in the table. so the table should fill with different kind of datatype variables.
There is a "how do I video" on how to properly control updates, inserts and deletes in multi-user applications on forms that edit master-detail related data. [URL] Massi worked through the process using Order (OrderID is PK) as the master table and Order Detail (OrderDetaiID is PK) as a related table in dataGridView. The dataGridView automatically generate orderDetailID whenever the mouse enters in a new row. I am doing a similar form, but placing order form and orderDetail form in two separate tabs in a tabcontrol, and also using Details view for both tables. When I click "new" button in BindingNavigator, the orderID is automatically generated. If I use dataGridView for my orderDetail tab, then the orderDetailID is automatically generated when the mouse enters. This allow me to insert/update tables correctly. However I need the Details View for my orderDetail form too. How do I get a orderDetailID automatically generated when user insert a new order and have the mouse click on OrderDtail tab?
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 am getting error when i connect to oracle DB. am using the connection string statement using ODBC DRIVER. i want to get some data from orcle db and bind it into some control. oracle client is installed in my machine.my db name is PINDB it's in another server.

I need to create a new tree view, that is linked to a particular table.
Each row in the table has a parent id that links back to the table's primary key, and that defines the node hierarchy. So that relationship needs to be indicated in the databinding.
Am I able to use the standard treeview control in Visual Studio 2008, or do I need something extra to make this work?
