VS 2008 MSChart - Plotting Non-numeric Value?
Feb 3, 2012I need to be able to plot (for example) the following values on a chart:
4.5
3.1
5.3
2.1
<1.0
2.5
The value <1.0 is there as we cannot give the exact value if it is less than 1 but we need to display it.
Is there a way of just displaying the datapoint label with '<1.0' as text, or something similar?
VS 2008 MsChart - Print A Distribution Chart Using Mschart

Serial Data And Plotting In VB 2010
Dec 2, 2011I'm fairly acquainted with VB but the underlying .Net and many of the controls and whatnot I'm not all that familiar with. Hence, I have a real hard time trying to come up with ways to solve certain problems. I figure the best way to start is try to get some general guidance and go from there.
I have an external electronic device that gathers data (no need for details here) and has an internal micro-controller that interfaces from the device to a USB port. I need to build a PC based program in VB 2010 that can get the data from the device and plot it on a graph...possibly a fairly customized graph. Let's assume there is already a driver for this device that sets up a COM port (pseudo-serial I guess it's called).
Now what part of the VB toolbox of methods, controls, objects etc (what's the terminology for that again?) should I be looking at to start such an application? I don't want specific code or anything like that but what areas in this "toolbox" should I be looking at to begin?
Line Graph - Plotting Set Of Data Using Function
Feb 20, 2012I am trying to plot a set of data using a function I have defined as an array:
Private Sub calculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculate.Click
range(1) = min.Text
For i = 2 To 100
[Code] .....
Range(i) I want to be my x values and fee(i) to be the y values. When I try to select range() and fee() as the x and y values for a series, I get an error because they are not of type double.
.net - MSChart Nearest Data Point?
Oct 27, 2011I use Mschart to produce charts. What I am trying to get is the nearest data point by where I click on the chart. The problem is that I can't find any connection between the HitTest values and the data point x/y values.Say, I clicked on the following point:
Dim result As HitTestResult = Chart.HitTest(e.X, e.Y)I have now values of X and Y where I clicked. How to associate it with the data point values?
What I want to achieve is to double-click on the chart which would find the nearest data point (x,y as integer) and knowing these values I would be able to recalculate other values based upon where the user needs it and double-clicks.

VS 2008 MSChart - Chart Area Axis's Aren't Drawn When No Data Plotted
Apr 2, 2009MS released the new MSChart for .net 3.5 sp1. I'm trying to get the hang of it in VS2008. One big issue I have is that if I have no data plotted the chart area axis's aren't drawn. Does anyone know a way around that? That seems like a pretty basic/common issue.
View 6 RepliesPlotting 2d Graph In C#.net?
Jan 19, 2011I was writing a program on a web form which is reading a file and then plot the file as a 2d graph.
the file looks like
c1
number1
number2
[Code].....
where c1 c2and c3 is the header which the readfile stream should ignore and the total "number" numbers are decided by the user which can be a variable.
the graph will take the c1,c2,c3values as x-axis and the number values as y-axis.
how can I draw the graph from reading this file? can some one kind enough to show me some code?
Application - Plotting X/Y Graph ?
May 4, 2009I wanted to plot a graph for one of my application in VB.net. I want a Time (X-axis) Vs Temperature (Y-axis) graph, where:
1. X- Axis has vertical lines every 10 minutes. So there are 6 vertical lines between 1 hr. The labels on the Axis should be written at every hour even though the vertical lines are at every 10 minutes. (Eg: 10:00, 11:00, 12:00, 13:00, 14:00...)
2. Y-Axis should have horizontal lines every 10 degrees C. So there are 10 Horizontal lines between 100 degrees. The labels on the axis should be written at every 100 degrees (Eg: 0 deg C, 100, 200, 300...)
Plotting Cartesian Plots In .net?
Oct 1, 2010I am new to VB.net. I need to plot some Cartesian plots in vb.net 2010 enterprise edition. This is what I need to show in the plot:
- individual x-y points
- curve connecting the points
- coordinate axis and possibly a grid
I have no idea how to plot this. Actually I'm not even sure which control I would use. Should I draw this in a pictureBox?

Plotting An Array Of Points On Button Click
May 9, 2011I have an global array of points that i want to plot in VB. say X and Y points, and typically they have values of +/-12000. Now I've not done graphics work for a long time and when I did, I used OpenGL with C. Now I need a GUI i'm using VB 2008. Firstly, what's the best method of rendering the array of points? should I use some port of OpenGL? GDI? or what?
Secondly, can I simply print to perhaps a Panel on hit of a button? Thirdly, do I have to place any line drwing code in an "OnPaint" event handler? Finally (for now) if my array represents points in a space much larger than the painting surface, how would I scale and scroll the final image within the the proposed Panel? I look forward to your advice.
Plotting Graphics And Output To Image File?
Feb 23, 2009I am a total beginner to software development, I have purchased a copy of Visual Studio 2008 and have been working through a self teach book on Visual Basic.NET. I have some ideas for applications that I want to develop and am in need of some pointers.
I want to plot graphical objects and standard lines and rectangles based on coordinate data that I have imported into an array from a tab delimited text file. I have some bitmap symbols that I have created and I want to plot these in my programme along with some labels and save the output as a bitmap file or other suitable image file.
I am having trouble finding any help in the online documentation and want know where I need to start. Do I plot the graphics directly onto a form or do I need to add them to a picture box? When I get this far how to I create the image file?
Plotting In A PictureBox Within A Loop And Passing Variables?
Feb 24, 2010This is my first attempt at doing something in VB.net. I would like to be able to read a text file consisting of a column of data values and then pass the data as a variable to a sub that produces a line graph and updates it with each iteration through the loop. So far I have the code to read the file as well as some code that produces a line graph using hard coded values.
I am unsure how to call this sub from my loop such that I can pass that data value read from the file to the graphing sub.
How can I call the "PictureBox1_Paint" sub from my loop? How can I pass variables read from the data file to "PictureBox1_Paint" when I am calling it? Is there anything different that needs to be done if I want the graph to update with each iteration through the loop (for each data point)?

VS 2008 Plotting Real Time Graph?
Jan 13, 2010Currently, my circuit is connected to a power supply and is connected to the computer via a RS232 cable. Voltage level is extracted and the real-time voltage level is plotted (see attached image) and it will keep movingBut you will realise that there isnt any time shown on the X-axis. I would like to display time in such a way:Each long marker will represent 1 second and there are 4 long marker, which will represent up to 4 seconds.When the (5th second) voltage is sense and the real-time voltage is drawn, i would like the new time (5th second) to replace into the 1st marker postion, the (6th second) to replace the 2nd marker position, so on and so forth. The replacement will continue

Mschart On Windows 7 64 Bit
Dec 5, 2011I've spent hours searching the internet on this, and found a bunch of posts with similar problems, but none of the solutions I saw have worked for me, so bear with me. I have an application that's a couple years old that has a form with a chart on it(using mschart). Worked on my old development machine, and most users. Eventually some users started letting me know that the chart wasn't working for them. The chart was a minor feature, and I was unable to reproduce the problem, so it kept getting pushed back.

Dynamic Textbox Data Has Been Changed?
Mar 3, 2009I have a form that builds and populates dynamic text boxes from parsing a file. There is a "Last Name" text box that when populated, also labels a tab page with the name. After the form is populated, the user can change data as they desire but I was wondering how to update the tab page text when the user updates the last name text box? All the controls are built in code.

View 3 RepliesHow To Create Dynamic Storage Of Data
Jan 26, 2012I'm a junior VB programmer and looking for some advice on this subject. I'm trying to create a chunk of code that will create dynamic storage for variables for use later by dynamic custom controls.
For example:
An INI file might have an entry in it that looks something this:
....
[var1] <-- this becomes the Storage name
description=My Variable
type=System.Int32 <-- this could be any valid VB type
last_val=456 <-- Other code would save the last value
....
And I want to access the data using a standard "property set" like so after it's created:
var1_reference.value = 55
I've tried using a generic class which works ok as long as I declare the variables at design time from within the design environment. But when I try to create them from the INI file it gets messy.
Here's the simple generic class i've constructed to test this:
Public Class GenericVar(Of T)
'
' Generic Symbol Class for data storage
'
Private VarName As String
Private VarType As Type
[Code] .....
Also, as each object is created (and they could be different types) I store a reference in an array to make it easier to keep track of, but I'm having a hard time getting access to the objects and their properties, and certainly cant seem to assign an event handler to it once its in an arraylist because the design time code doesn't know what "Type" it is in the arraylist of objects.
Streaming Dynamic Data In Array?
Oct 6, 2009I am attempting to figure out the best way to place values into an array using dynamic data that is continuously streaming in from a ComPort. I want the array to hold 5 values at a time, with the newest incoming data point taking the place of the oldest data point. Each set of values in the array will be used in finding a trendline, which is then used in a later portion of the code.
View 1 RepliesVS 2008 : Add Dynamic Data To Datatable?
Oct 4, 2010I am creating a data logger that pulls data from an existing OPC server. When the data logger is launched, I look into the OPC server and get the names of the sensors that need logging (ColumnNames() as string) . From that, I am creating a data table with columns based on the items in ColumnNames(). That part is working. What I am having problems with is adding rows to the table. When I read the values from the OPC server, I get an array of strings (values() as string) which is guaranteed to be in the same order as the ColumnNames.I have been trying to use an SqlDataAdapter with a dynamically built insert command, but it is getting extremely convoluted and ugly.Is there an way to add a data row to my table using an array of string values directly?
