I have a 70x16 array of values ("DATA22K") imported from a .xls spreadsheet, with the x-values (time) being column 1, and the fluorescence intensities of 15 samples (over time) being columns 2 thru 16.

I wanted to create lists in an iterative fashion to easily plot and analyze the samples. I have written two approaches, assigning variables such that each list variable corresponded to the trial number for each sample. The approaches are:

1) Do[Evaluate[Symbol["Tr22K" <> ToString[i]]] == Transpose[{Time22K, FRAP22K[[All, i]]}], {i, 1, 15}];

in which I've used simple variable assignment and span to separate the time column ("Time22K") from the sample data ("FRAP22K"), and:

2) Table[Evaluate[Symbol["Fr22K" <> ToString[i]]] == Transpose[{DATA22K[[All, 1]], DATA22K[[All, i]]}], {i, 2, 15, 1}];

Both approaches create the lists (though approach #2 returns a list of "false" values when clicking ""show output"), but when I run ListLinePlot[Tr22Ki], neither approach produces a graph-- I have to plot each list created individually.

How can I perform functions and commands on all the lists produced (not just plot)?

Thanks for your time.

    $\begingroup$ This make your lists lists=Table[Transpose[{DATA22K[[All, 1]], DATA22K[[All, i]]}], {i, 2, 15, 1}]; and after to apply a function say, ListPlot, you can do Map[ListPlot,lists] $\endgroup$ – user48983 Jun 29 '17 at 2:23
  • $\begingroup$ This works, but I would like to store the values for each plot with a variable name, such that I can reference the lists individually later. Is there a way I can do so with this format? Ultimately, I will be analytically extracting certain parameters from the datasets via curve-fitting. $\endgroup$ – JMart Jun 30 '17 at 1:01
