tcolorbox: problem with alignment of text

Question

I have created 3 tcolorbox, one left, one right and one down. The idea is for the text to be at the left of the graph, at the right and below of the graphs ( I included the graphs so it can be better explained.

The problem I can't fix is the alignment. I want the text justified in the 3 cases (keft, right and down), but all I get is flush left text.

I hope this makes sense, thanks!

Here is the code:

Answer 1

I found what the problem was, I was using

halign=left,

And that was the cause of the problem. As suggested by @David Carlisle, the justified was the default setting, so I was overriding it with this command.

Thanks for the time.

Answer 2

Adding \justify{\lipsum[1]} with \usepackage{ragged2e} works to justify
