From Review-beta I edited a low quality question where it looked like the question was in the title and only completely understood by viewing the tags too. I did notice it was an old question.
On looking later I saw there was an accepted answer that referred to the OP's code.
So looking at the edits the OP came and deleted all but the last line of their question about a month after the accepted answer was provided.
I think we should revert their (and hence my) edit, otherwise the answers don't make much sense, but I'll let someone else decide to do that.
This also suggests older answered questions may not be relevant for low quality questions.
The question: trying to show the two graphs on same page
