Plotting multiple arrays on same graph

I am a little confused about how I should plot arrays. I am often confused with Charts and Chart Objects. I would like to pass arrays into a function that plots the arrays. In the main code getPlots I would like to make each column an array and divide it by the first column/array (I also need the first column divided by itself). In the plotting function, I often have an invalid parameter error, but I think my confusion comes from whether I am dealing with charts or chart objects. It happens in the plotting function in the line that says with activechart...

I should add that the timeArray represents the x-values.

Your post does not comply with Rule 1 of our Forum RULES. Your post title should accurately and concisely describe your problem, not your anticipated solution.

Use terms appropriate to a Google search. Poor thread titles, like Please Help, Urgent, Need Help, Formula Problem, Code Problem, and Need Advice will be addressed according to the OP's experience in the forum: If you have less than 10 posts, expect (and respond to) a request to change your thread title. If you have 10 or more posts, expect your post to be locked, so you can start a new thread with an appropriate title.

To change a Title go to your first post, click EDIT then Go Advanced and change your title, if 2 days have passed ask a moderator to do it for you.

(This thread should receive no further responses until this moderation request is fulfilled, as per Forum Rule 7)

@NatalieEC: it is not very practical or sensible to edit your original post ... especially is you replace it with a completely different question and code, as you have done. It makes nonsense of any responses you might have had to the original question. And it leaves everyone wondering what they are supposed to be resolving.

Where did you get the answer to the question that is no longer visible to us?

No problem. I suggest that you mark this as Solved and start a new thread.

That way you'll get fresh eyes looking at your current problem.
