View 20 RepliesThe picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.

View 2 RepliesI have a large set of latitude and longitude coordinates from a GPS which, when plotted, creates a 'jerky' line over time. I would like to 'smooth' this line into another set of coordinates which I can then plot to make the track more 'smooth'.
I may need to add more intermediate coordinates to do this. I just wondered if there are any code snippets out there or even MS Excel functions
I am trying to write a function in VB.NET that takes a value and returns it's y-position on a Bell Curve.
View 4 RepliesI'm working in .net 2005. I have a collection of points and I'm creating a polyline with them; however, I need to curve fit them so that they appear to be some what straighter.
If you look at my picture, you can see the blue dots represent the points and the red line is a represenation of how I'd like the final results to be. (Basically, I need to line to appear straighter and less jaggedy looking than it is now).
I didn't know if I should try to see if there's some plug-in for doing this or if vb.net has anything I could use to do this myself.
I am looking for a way to be able to export a beizer-curve (a curve like in the example below)from my app to a DXF-file.What I need is a way to calculate the control-points and parameters that DXF-format requires (format as in link below)
View 11 RepliesWrite a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
View 1 RepliesHow hard would it be to graph a curve of a function in a VB form.
Attached is a graph from excel which is exactly what I need to do.
I have the function of some fluid properties and I'd like to choose a min and max temp then have the function graphed, with temp as the x and the fluid property as the y which would auto scale to fit the curve.
Actually now the program i have to return the properties at one temp is just a GUI front end to call a fortran program to return the properties so actually if I just use that it'd be graphing points and not directly from the function. I can always make it completely VB based if graphing from a function is easier than points. It'd be a slight pain to rewrite all the code for the functions though.

View 14 RepliesMy problem is centering the 0,0 points of my graph to the center of my picturebox
Dim picBoxWidth As Integer = picGraf.Size.Width
Dim picBoxHeight As Integer = picGraf.Size.Height
Dim halfWidth As Integer = picGraf.Size.Width / 2
[code]....
So how to I tell it to start at the center of my picturebox names (picgraf) btw.
This question may be off-topic. If it should be posted in another place (even on another board) For some given curves (see sample below) I have to quantify whether the red dots in some regions of the curve are more dense at the upper or lower edge of the curve. Which algorithm might be adequate to perform this task? The curves are constructed from measurements. (No mathematical formula behind it.) Every data point has two dimensions: A value in the range 4000-7000 and a second value 0-255.

View 1 RepliesIs there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?
Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.
I got one reply early of:
If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then
'There is no RadioButton checked in myGroupBox.
End If
Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.
