QUESTION
I am trying to join some Time series CSV files on different stocks. I manage to get my data in separate CSV file and now I want to join them all together with Date as an Index and keep only their closing price. To identify which closing price corresponds to which ticker I have to rename the column "Close" to the name of the ticker that is contained in the filename. The files have all the following naming convention: "ticker.csv". This code is inspired from a website pythonprogramming.net and I tried to adapt if to my situation. (link here: https://pythonprogramming.net/sp500-company-price-data-python-programming-for-finance/)
I already looked up a lot of solution online but none answered my problems.
Why is my code telling me there is a keyerror when I try to set Date as an Index?

Answered 2018-Jun-29 at 09:39Basically you are keeping on appending more and more to the popover on every click.
Do this instead:
Create a variable
i
and initialise it as i=1
(Do this outside the onclick triggered function or it will keep on re-initialising to 1 ). Inside your function check if i==1
if it is true use your current code and increment it by 1.
else if check i
is divisible by 2 -> if it is true hide it,
else -> show it.
