How to use a mathematical expression as xticklabel












2















I have prepared a code including some data resulting in a bar plot. I want to use a mathematical expression as xticklabels but my code does not work. How can I figure this point out?



Here is my code:

          There were two issues:




          1. in the last plot you had coordinates twice.

          2. for some reason, pgfplots does not like a to. The deeper reason can be presumably found in pgfplots.code.tex, where to is used in many macros.


          I acknowledge that John Kormylo beat me by seconds (while I was typing the explanation).

          • Dear @marmot, as it can be seen, for each xtick there are three bars, but all of them are next to each other. How can I make a space between each xtick?

          • @HadiSobhani You might want to increase the width of the plot, e.g. pgfplotsset{compat=1.16,width=17.5cm} and decrease the padding, e.g. enlarge x limits=0.04, instead of 0.1.

          Tikz redefines to. Use rightarrow instead. Also, it seems that symbolic x coordinates and xticklables are incompatible.

            with use of pgfplotstable you will not have problem with use of to math symbol. beside this code is simpler, a bit shorter and to my opinion more clear. based on my answer on your previous question, i rewrite your mwe to:

              There were two issues:




              1. in the last plot you had coordinates twice.

              2. for some reason, pgfplots does not like a to. The deeper reason can be presumably found in pgfplots.code.tex, where to is used in many macros.

              • Dear @marmot, as it can be seen, for each xtick there are three bars, but all of them are next to each other. How can I make a space between each xtick?

              • @HadiSobhani You might want to increase the width of the plot, e.g. pgfplotsset{compat=1.16,width=17.5cm} and decrease the padding, e.g. enlarge x limits=0.04, instead of 0.1.

              • Dear @marmot, as it can be seen, for each xtick there are three bars, but all of them are next to each other. How can I make a space between each xtick?

              • @HadiSobhani You might want to increase the width of the plot, e.g. pgfplotsset{compat=1.16,width=17.5cm} and decrease the padding, e.g. enlarge x limits=0.04, instead of 0.1.

              There were two issues:




              1. in the last plot you had coordinates twice.

              2. for some reason, pgfplots does not like a to. The deeper reason can be presumably found in pgfplots.code.tex, where to is used in many macros.

                  Tikz redefines to. Use rightarrow instead. Also, it seems that symbolic x coordinates and xticklables are incompatible.

                          with use of pgfplotstable you will not have problem with use of to math symbol. beside this code is simpler, a bit shorter and to my opinion more clear. based on my answer on your previous question, i rewrite your mwe to:
