I have a large data set. I am trying to use a for lop, to be able to select which coloumn i want to keep and which ones i want to discard, all depending on the user input.
I managed to do that part, i believe.
Now I am trying to get an average value for each coloumn and plot the results in a scatter graph. I tried to do this using a for loop.
But there is only one data set that appears on my scatter graph, so I assume it cancels the ones that were before that last point. I used hol all, hold on and draw now, but could not get it to work. Also I would like add a line of best fit for the scatter graph for each data set and save slope and intercept numbers in a table.
I managed to do do the line of best fit and slope, intercept before, but not since I am trying to use for loops, so I put my old code segments in a comented out section.
In the first version of the code, i just determined the coloumns ( channels ) i want to use in the code, not depending on user input.
I cannot upload the excel file that I use, because it is too big. i tried to compress, but did not work
