Hello all,
I have given up on trying to change vb6 code to .net and instead am going to try to rebuild in .net. What would be the best basis of code for the user to select an excel file, process the file to populate a graph from the data in specified columns, and then draw in lines of best fit to the data. I have attached an example of what the data format is consistently. As you click on the forward button it goes to the next row of data and redraws the corresponding graph. Things I am trying to figure out how to do:
1) Open two csv's and read the data (x-axis by columns and y-axis by rows)
2) Take the csv with increasing values on column E and plot on the right side of the y-axis
3) Take the csv with decreasing values and plot on the left (in line with the matching value from column E)
4) Have the title of each graph be the value in column E.
What do you think would be the best form components to achieve this basic initial step and how do you use .NET to create a graphic of your data plotted with additional fit lines? Thank you in advance for your time.

This is an example of some code I wrote in excel VBA that was part of another procedure which might help clarify the layout.
