x axis labels are getting repeated twice for a bar-chart [duplicate]

Question

Problem 1: I am trying to generate a bar-chart with 3 bars for each chart. But as you can see from the below output, my x-axis labels are getting repeated twice. X axis labels = {3-6, 6-12, 12-24}

Problem 2: When I compile the code on overleaf, I get the picture in the center in a full and when I paste the code in another document, it occupies lot of space (as the whole pdf page is being coped to another document). Is there any way that when I compile the project, I just get a pdf download which just confined to that image?

Can anyone help me with this problem?

Thanks!

Answer 1

• Your question is not entirely clear, for example, how you insert this image in your real (final) document?
• For figure positioning on page, try to use placement position options, i.e. instead \begin{figure} write \begin{figure}[ht] or \begin{figure}[!ht].
• After cleanup your groupplot settings as is done in MWE below, and a after wee bit reorganizing your figure code, the compilation on the local MiKTeX installation as well in the Overleaf gives the same result.
• The clean-up is done in spirit of my answer on your previous question (no need to add xtick option):

Answer 2

Regarding Problem 1: Adding the xtick command with the symbolic labels (see below) did the trick for me.

Regarding Problem 2: If I understood correctly, replacing the article class from document to standalone did it for me (I had to remove the figure environment + the caption)
