Chart Control - Creating Graphs Using Crunched Data Stored In Array List
May 7, 2010
Recently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?

I'm trying to plot a graph in VB.Net, using MS Chart Control. I'm receiving streaming data, distance vs X data (Sine wave) and Z data (Cosine wave) every 1 msec. maximum data points varies from 2000 to 5000. I would like to plot this streaming data on a graph, distance on x-axis and two series X data and Z data on Y axix.

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?

I am working on an inventory managment project for a lumber mill. I am currently writing a piece of software to be used on the sorting section of the mill. The problem I am having is when a stick of lumber needs to be cut down in lengt. My current setup has a combo box that is populated with lengths of lumber that we might have (2' - 60'), a "Add" button and a data control (homemade solution with lots of labels, and panels).
The user will scan a tag into the system, and the system pulls up the info from the db. If the piece need to be cut, the user will select the length of the cut, and click the add button. The system will then populate the first line of the data control with the info from the cut (previous piece info, and new length). It also populates a pieceObject struct. This happens for any additional cut that might happen.
The problem I am having is that everytime I press the "Add" button, the length variable will update every length in the piece array.
Here is a section of the code I am dealing with.
piece is a lumberPiece, and pieceAry is a array of 15 lumberPieces
Each time the add button is pressed, the current data is stored into the array, and then the pieceNum is incremented.

I have this rather stupid litle excel issue which somehow just doesn't go away by itself;I'm creating a excel chart from three rows of information data. Each row has a header, so far so good. The first row exixt of calender data and I planned it to use them as my x-axis labeling. But somehow excel uses them as variables and changes them in to a third bar. Which is not what I had in mind when copied this litle piece of code.[code]

So I have a 2D array of data, specifically, one "Cv" value for every 10% increment. I have been able to get the Cv's plotted vs % open with the following method:
Private Sub btnPlot_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlot.Click
Dim tempString As String
[Code]....
I haven't yet looked into this, but if there's any way to also export this graph as an image into an excel spreadsheet, We will be creating several spec sheets as excel workbooks and we will need to be outputting standardized sheets, which is why I'm trying to make this an application instead of directly implementing the code in Excel with VBA.

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 a macro run program I have created using excel 2007.The excel version makes use of VBA designed userforms and macro code to run and it stores data within a worksheet.It populates some of the fields in the userforms from drop down boxes whose pre-populated values are stored within another worksheet in the workbook.If I was to create this within vb.net how would the drop down box values be stored? and also: would it be easy to have the userform on-close click event send the data to be stored in an excel workbook ?

I'm trying to create a small program where someone would select one of five items from a list box (Hot, Medium, Mild, Sweet, Zesty). When they select this, they then enter in a qtyTextBox the quantity they want, ie.e, 1, 2, 3, 5,... Then they the Calculate Button, which then the total would go into the preDiscountLabel box, where it would calculate the amount they want * the sale price. Here is the Price Listing:
Hot - 3.19
Medium - 3.09
Mild - 2.98

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.

I'm having trouble creating a global array that i can use in other functions.
I have this code right under "Public Class myClass":
Dim LoadedPlugins As Array
Then in a function I have this:
Dim PluginList As String() = Directory.GetFiles(appDir, "*.dll")
For Each Plugin As String In PluginList
Dim Asm As Assembly
[Code]....
Now obviously that doesn't work, how can I add the tmpPlugin to an array or list so I can use it in other functions?
The main thing I need to be able to do is loop through all the loaded plugins and execute the CustomFunction in a separate function than the one that loads the plugins listed above.

I need to dynamically create some sort of 'table' on my form. It should look like:
PIC1 INTEGER1 TIME1
PIC2 INTEGER2 TIME2
PIC3 INTEGER3 TIME3
On top of that it should look like a table and have gridlines between the 'cells' containing the picture/data, which makes it even more difficult for me. Before, control arrays were quite simple in VB6, but I've been searching for 1,5 hours now and I can't figure out how to do this in VB.NET 2010. Any idea how to tackle this the most efficiently?

I have an array of picture boxes as so:
Dim pieces(500) As PictureBox
pieces(1) = New PictureBox
With pieces(1)
[Code].....
The program does not crash or anything, but the picturebox is no where to be seen on the form. How to I make this work correctly?
And is 'Control Array' the correct term for this? or something else?

I have a stored procedure that takes in 2 parameters and returns an integer value. I would like this value to be the value for a gauge chart on the page. The 2 parameters will change depending on the attributes of the selected item. Is there a simple way to pass the one value from the stored procedure to the chart to display? This will be embedded in an asp.net application (vb) - so depending on the previously selected item, the values for the parameters and result will change.
