View 2 Repliespoints on picture box by several mouse down operation, perform either linear regression for best fit straight line for these points or best fit circular curve fitting for these points.User can use radio button to select either straight line or circular curve fitting. Plot the best fit graphic accordingly and save these graphic to a data file (result.txt).

Those files have some list of values as x and y ordered as line by line.
And my question is just I would like to read those files one by one and to plot line graphs based on those values.
ive been struggling on this portion of my code for almost 3 days with no luck. i have a database containing a list of transactions (in this case, the product name, quantity and date of sale). I want to plot a graph for each product showing the amount sold each month for the past 12 months. The functions to calculate these values are working fine. but my problem is this:
each tab page is named after the product name:
TabControl_SaleOfProducts.TabPages.Add(
"TabPage_"
& ProductName, Item)
and then to this tab page i want to add the graph. but i cannot reference the newly created tab page?
I need to be able to take an MP3 or WAV file and plot a graph of its waveform over time. Prefferably without playing it first. The representation doesn't have to be amazingly accurate as it's not for EQ purposes. I just need to pinpoint certain points in the MP3 / WAV when specific music / sounds etc occur (similar to the display in Windows Sound Recorder).
how I can go about that, or if it's even possible in VB 2005?
I'm currently trying to use ZedGraph to plot a graph based on some data I have extracted from a machine, with reference to a user entered "Frequency" range. I has to be a line graph, with Frequency on the X-axis, and extracted data on the Y-axis. There are 4 channels for the machine, but all data values extracted are close to each other, so multiple Y-axes are not needed. I'm also trying to do it within a class, and the graph should only be drawn when I click "Button3", otherwise there would be no data anyway and button2 extracts the data.
Below are my class (the graph code is at the bottom) and form1, which button3 should call the class, but I'm stuck for both the button interfacing and the class writing. I have also attached the output I get so you can have a look at what I need. Open it in Excel to see the format. The whole program is also attached as a text file if you prefer it that way.

View 2 RepliesI have been learning and developing a software using VB for my company. I seem to have some issues with Chart function. [Code] Those 2 points will plot 2 datas (xval, finvall) & (xval, finvall2). Here is the thing. When I do the plotting, the starting points are always at (0, 0). That points come from the data point collector editor in the series properties. The question is: How do I plot data using the first value that I have? I don't want to start at (0, 0) but instead using (xval, finvall) & (xval, finvall2). I can't change the data point at run time. Many thanks!

I have the DirectX SDK, but I'm not sure where to start with it and need some direction.
