View 2 RepliesSmoothing A Line To Become A Curve?
Jan 3, 2012I 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

View 4 RepliesCurve Fitting Through A Collection Of Points?
Jun 23, 2011I'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.

Dec 19, 2011Write 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 RepliesGraph A Curve Of A Function In A VB Form?
Jul 9, 2009How 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 1 RepliesVS 2008 How To Calc Curve Points
Jul 26, 2010The 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 3 RepliesDots More Dense At Upper Or Lower Edge Of Curve (searching Algorithm)?
Mar 2, 2011This 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 6 Replies.net - Best Control To Draw In?
Aug 16, 2011I have a VB app which draws primitive shapes (lines, filled rectangles etc.) into a picturebox control (from its paint event). I've since found out that a picturebox is probably the worst control to use for this. I've also found out that it's better to draw directly onto the form but I don't really want to do this as a control gives clipping for 'free'.
What would be the best control for this? The panel control looks like a good candidate but the experiment I tried actually performed worse
